#wrapper class in java

[triviallytrue]

also i hate to shit on a guy who made a really cool open source tool but like. java really fucking sucks to read. trying to figure out where the actual logic is happening in the infinite cruft of classes and boilerplate methods and wrappers and factories is exhausting

How to Convert Character to String in Java

In Java, converting a character (char) to a string (String) is a common operation. Java provides multiple ways to achieve this, each suitable for different use cases. This article how to convert character to string in java a character into a string efficiently.

Using Character.toString(char c)

Java provides a built-in method Character.toString(char c) that converts a character into a string.

Example: char ch = 'A'; String str = Character.toString(ch); System.out.println(str); // Output: A This method is simple and recommended for converting a single character to a string.

Using String Concatenation

You can concatenate an empty string ("") with a character to convert it into a string.

Example: char ch = 'B'; String str = "" + ch; System.out.println(str); // Output: B This approach is widely used because of its simplicity and readability.

Using String.valueOf(char c)

The String.valueOf() method is another way to convert a character to a string in Java.

Example: This approach is widely used because of its simplicity and readability.

Using String.valueOf(char c)

The String.valueOf() method is another way to convert a character to a string in Java.

Example: This approach is widely used because of its simplicity and readability.

Using String.valueOf(char c)

The String.valueOf() method is another way to convert a character to a string in Java.

Example:

Using Character Wrapper Class and toString() Method

Java allows using the Character wrapper class with the toString() method to convert a character to a string.

Example:

Character ch = 'D'; String str = ch.toString(); System.out.println(str); // Output: D This method is useful when dealing with Character objects instead of primitive char values.

Using StringBuilder or StringBuffer

If you are dealing with multiple character conversions, using StringBuilder or StringBuffer can be efficient.

Example: char ch = 'E'; StringBuilder sb = new StringBuilder(); sb.append(ch); String str = sb.toString(); System.out.println(str); // Output: E This approach is useful when working with dynamic strings that require multiple modifications.

Conclusion

Converting a character to a string in Java is straightforward and can be achieved using various methods, including:

Character.toString(char c)

String concatenation ("" + char)

String.valueOf(char c)

Character.toString()

StringBuilder or StringBuffer

I was trying to do some Index writing speed improvement and thought of creating a asynchronous Lucene index writer. This writer provides a addDocument() method which can be called asynchronously by multiple threads. Here are the few scenario where you can utilize this implementation - Reading the data is slower then writing to the index. (Typical scenario where you read over network, or from database.) - Reading can be divided in multiple logical parts which can be processed in separate threads. - You are looking for asynchronous behavior to decouple reading and writing processes. This implementation is a wrapper which utilizes core methods of IndexWriter class, and does not do any change to it except making it asynchronous. It utilizes Java's java.util.concurrent.BlockingQueue for storing the documents. It can be supplied with any implementation of this class using its constructor. Below is the Java source of this implementation class This class provides multiple constructors to have better control. Few terms which are used here are as follows Sleep Milliseconds On Empty: This is the sleep duration when writer finds nothing in queue and wants to wait for some data to come in queue. () Queue Size: This is the size of the queue which can be configured as a constructor parameter input. AsynchronousIndexWriter.java package swiki.lucene.asynchronous; import java.io.IOException; import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.BlockingQueue; import org.apache.lucene.document.Document; import org.apache.lucene.index.CorruptIndexException; import org.apache.lucene.index.IndexWriter; /** * @author swiki swiki * */ public class AsynchronousIndexWriter implements Runnable /* * A blocking queue of document to facilitate asynchronous writing. */ private BlockingQueue documents; /* * Instance of core index writer which does the actual writing task. */ private IndexWriter writer; /* * Thread which makes writing asynchronous */ private Thread writerThread; /* * We need to set this to false if the document addition is completed. This * will not immediately stop the writing as there could be some documents in * the queue. It completes once all documents are written and the queue is * empty. */ private boolean keepRunning = true; /* * This flag is set to false once writer is done with the queue data * writing. */ private boolean isRunning = true; /* * Duration in miliseconds for which the writer should sleep when it finds * the queue empty and job is still not completed */ private long sleepMilisecondOnEmpty = 100; /** * This method should be used to add documents to index queue. If the queue * is full it will wait for the queue to be available. * * @param doc * @throws InterruptedException */ public void addDocument(Document doc) throws InterruptedException documents.put(doc); public void startWriting() writerThread = new Thread(this, "AsynchronousIndexWriter"); writerThread.start(); /** * Constructor with indexwriter as input. It Uses ArrayBlockingQueue with * size 100 and sleepMilisecondOnEmpty is 100ms * * @param w */ public AsynchronousIndexWriter(IndexWriter w) this(w, 100, 100); /** * Constructor with indexwriter and queue size as input. It Uses * ArrayBlockingQueue with size queueSize and sleepMilisecondOnEmpty is * 100ms * * @param w * @param queueSize */ public AsynchronousIndexWriter(IndexWriter w, int queueSize) this(w, queueSize, 100); /** * Constructor with indexwriter, queueSize as input.

Here are few things to note, asynchronous thread is started as soon as you instantiate using new AsynchronousIndexWriter(...) TestAsyncWriter.java package swiki.lucene.asynchronous; import org.apache.lucene.analysis.standard.StandardAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.document.Field; import org.apache.lucene.index.IndexWriter; import org.apache.lucene.store.Directory; import org.apache.lucene.store.FSDirectory; /** * @author swiki swiki * */ public class TestAsyncWriter public static void main(String[] args) try Directory fsdir = FSDirectory.getDirectory("index"); IndexWriter w = new IndexWriter(fsdir, new StandardAnalyzer(), true); AsynchronousIndexWriter writer = new AsynchronousIndexWriter(w); /* * This call can be replaced by the logic of reading * data using multiple threads */ addDocumentsInMultipleThreads(writer); writer.optimize(); writer.close(); catch (Exception e) e.printStackTrace(); private static void addDocumentsInMultipleThreads( AsynchronousIndexWriter writer) throws InterruptedException //add here the code for adding document from multiple threads.

Writeup: The Great(?) OpenGL Wrapper Race

Somehow, I always find myself gravitating back to the S3 ViRGE/DX.

This time around, rather than placing total focus on the ViRGE itself, we'll be taking a look at some OpenGL wrappers!

This writeup will be updated along the way as more videos release.

The setup is as follows:

Matsonic MS7102C

Windows 98SE RTM with the following patches/update: KernelEX 4.5.2, NUSB v3.3e, Windows Installer 2.0, DirectX 9.0c

Intel Pentium III (Coppermine) @ 750MHz

S3 ViRGE/DX @50MHz w/4MB EDO DRAM (using the S3 Virge "SuperUni" drivers)

256MB PC-133 SDRAM (Kingston KVR133X64C3/512) (System can only handle 256MB per DIMM)

Sound Blaster AWE32 CT2760

Some random 5GB Hitachi 2.5" HDD that I "borrowed" from a very dead laptop

Java 6 (1.6.0) build 105/Java 6u0

Wrappers to be tested:

S3Mesa - a wrapper based on the Mesa project. It's a full OpenGL implementation sitting on top of S3D and Direct3D, but from the available source code appears to be missing some functionality and is quite unstable.

AltOGL - also a wrapper based on the Mesa project, but relies solely on Direct3D. It is similarly missing some functionality, but is much more widely compatible with cards beyond the Virge thanks to its lack of reliance on S3's proprietary API.

Techland S3D - one of the many wrappers made by Techland for their Quake II engine-based "Crime Cities" game. Although it like S3's own GLQuake wrappers only implements as much of the API as is needed by the engine, it still implements far more features than S3's DX5 and DX6-based wrappers, of which are not tested in this wrapper race.

Techland D3D - like AltOGL, Techland's D3D counterpart to their S3D wrapper implements a subset of the OpenGL spec, but still enough to be compatible with a number of titles beyond Quake II engine games.

GLDirect 1.x - A very early version of GLDirect. There exists a license code for this version floating around on the internet that appears to have been used for internal testing by Shuttle, a PC manufacturer that's largely fallen out of relevance and mainly does industrial PCs nowadays.

GLDirect 3.0.0 - One of the last versions of GLDirect to support hardware acceleration on DX6-class graphics cards.

Things tested

WGLGears

ClassiCube 1.3.5 and 1.3.6

Minecraft: Indev in-20091223-1459, Alpha 1.0.4, Beta 1.7.3 (with and without Optifine), Release 1.5.2

Tux Racer

GL Excess benchmark

Half Life 1 v1.1.1.1 KingSoft NoSteam edition

Findings

GLDirect 1.01

OpenGL Version String

Vendor: SciTech Software, Inc. Renderer: GLDirect S3 Inc. ViRGE/DX/GX Version: 1.2 Mesa 3.1

Textures do not work at all in every test case besides Half Life.

ClassiCube 1.3.5 and 1.3.6 both fail to render any terrain beyond a greyish horizon and the outlines of blocks. All blocks, items, and text that are able to be rendered are pure white in color and have no textures applied.

Minecraft Indev in-20091223-1459 and Beta 1.7.3 with Optifine crash upon world-load

Minecraft Alpha 1.0.4, Beta 1.7.3, and Release 1.5.2 all crash upon launch.

Tux Racer is able to render 2D textures such as text and graphics, but flickers INTENSELY and is a seizure risk. Beyond this, however, the game will only render a solid white screen.

Half Life launches and runs, but at a terrible 4 FPS. The game lags hard enough that the tram in the opening area of the game is frozen where it is, preventing the player from accessing anything beyond the intro cutscene.

GL Excess crashes instantly.

Performance

GLGears: ~76 FPS

ClassiCube 1.3.5/1.3.6: Unknown; game fails to render

Minecraft in-20091223-1459: Unknown; world crash

Minecraft Alpha 1.0.4: Unknown; crash on game launch

Minecraft Beta 1.7.3: Unknown; crash on game launch

Minecraft Beta 1.7.3 w/Optifine: Unknown; world crash

Minecraft Release 1.5.2: Unknown; crash on game launch

Tux Racer: Unknown; game fails to render in a VERY seizure-inducing way

Half Life: ~4 FPS; gameplay outside of training room is broken

GL Excess: Unknown; instant crash

GLDirect 2.00

From here on, GLDirect is split between "Game" and "CAD" wrappers, denoted by either a "G" or a "C" after the version number where written in this writeup.

OpenGL Version String (2.00C)

Vendor: SciTech Software, Inc. Renderer: GLDirect S3 Inc. ViRGE/DX/GX Version: 1.2 Mesa 3.1

OpenGL Version String (2.00G)

Vendor: SciTech Software, Inc. Renderer: GLDirect Version: 1.1

GLDirect 2.00C likes to complain about insufficient color precision.

Changing the color precision from 24-bit up to the maximum 32-bit color does absolutely nothing.

The CAD wrapper very clearly is intended for non-gaming workloads given how easily it crashes things. However, it is strange that it is labeled as a "maximum compatibility" wrapper/driver.

I am not using the SciTech GLDirect 3.0 driver beta seen in the video because it requires a card capable of higher DirectX versions than 6, which is what the S3 ViRGE supports. I may revisit this video idea with a later graphics card in a future video for more thorough testing.

Using the 2.00G wrapper, Minecraft Alpha and Beta have many visual bugs. Text is not rendered at all, for example, and the world selection screen is eerily dim compared to what it should be. Beta in particular extends this darkness to the title screen as well.

Under 2.00G, Minecraft Beta 1.7.3 with Optifine no longer has this darkness.

Under 2.00G, Minecraft Release 1.5.2... inverts the colors of the Mojang logo?

Did you know that if you fall out of the Half Life intro tram in just the right place, you get to see the multiverse?

The framerate starts to rise when this happens, as it appears that the tram after becoming unstuck will trigger the next loading screen. Unfortunately, this loading screen appears to be what seals your fate. Once the tram stops though you at least get to meet biblically-accurate Half Life rendering in a smooth double-digit framerate!

Performance (2.00C)

GLGears: 63 FPS

ClassiCube 1.3.5/1.3.6: Unknown; game fails to render

Minecraft in-20091223-1459: Unknown; crash on game launch

Minecraft Alpha 1.0.4: Unknown; crash on game launch

Minecraft Beta 1.7.3: Unknown; crash on game launch

Minecraft Beta 1.7.3 w/Optifine: Unknown; crash on game launch

Minecraft Release 1.5.2: Unknown; assumed crash on game launch based on previous versions' behavior

Tux Racer: Unknown; game fails to render (no longer seizure inducing at least)

Half Life: Unknown; crash on game launch

GL Excess: Unknown; instant crash

Performance (2.00G)

GLGears: 390 FPS; only a black screen was rendered.

ClassiCube 1.3.5/1.3.6: 10-30 FPS range, ~12-15 FPS on average; most of the game still does not render, but text, the hotbar, hand items, and very occasional flickers of geometry do render. Seizure warning.

Minecraft in-20091223-1459: Unknown; crash on world load

Minecraft Alpha 1.0.4: Unknown; crash on world load

Minecraft Beta 1.7.3: Unknown; crash on world load

Minecraft Beta 1.7.3 w/Optifine: Unknown; crash on world load

Minecraft Release 1.5.2: Unknown; crash on game launch

Tux Racer: Unknown; crash on game launch

Half Life: 4-5 FPS; game physics are almost entirely broken down and I'm pretty sure you end up phasing into a higher plane of existence along the way. Trying to enter the training room crashed the entire PC afterwards.

GL Excess: Unknown; instant crash

GLDirect 3.00

OpenGL Version String (3.00G)

Vendor: SciTech Software, Inc. Renderer: GLDirect Version: 1.1

OpenGL Version String (3.00C)

Vendor: SciTech Software, Inc. Renderer: GLDirect S3 Inc. ViRGE/DX/GX Version: 1.2 Mesa 3.1

GLDirect 3.00, both the CAD and Game versions, appears to behave identically to GLDirect 2.00 in almost all cases unless stated otherwise.

Performance (3.00G)

GLGears: 249 FPS; gears are rendered completely incorrectly

ClassiCube 1.3.5: 15-20 FPS on average; most of the game fails to render and the system hard-crashes after a few seconds.

ClassiCube 1.3.6: Insta-crash.

Minecraft: Crash on world load across all versions. Didn't bother testing Release 1.5.2.

Tux Racer: Unknown; crash on game launch

Half Life: ~4 FPS; extremely choppy audio in tutorial level.

GL Excess: Unknown; instant crash

Performance (3.00C)

GLGears: 80 FPS; Perfectly rendered

ClassiCube 1.3.5/1.3.6: Unknown; renders a white screen

Minecraft: Crashes on game launch. The game may also complain about color depth here.

Tux Racer: Unknown; renders a white screen

Half Life: Unknown; renders a white screen and then crashes on game launch

GL Excess: Unknown; instant crash

Techland S3D

We've now moved on from GLDirect! From here on out, each wrapper is instead a discrete opengl32.dll file that must be dropped into the folder of whatever program you'd like to run it with.

OpenGL Version String

Vendor: Techland Renderer: S3 Virge 3093KB texmem KNI Version: 1.1 beta 6

Right off the bat, things appear to be taking a turn for the interesting as GLGears fails to render anything.

Performance

GLGears: 60 FPS, but only because a black screen is rendered.

ClassiCube 1.3.5/1.3.6: Crashes on game launch but renders a solid blue screen.

Minecraft in-20091223-1459: We load into a world! Have fun trying to play it though. Rendering is very flickery and broken. It may be possible that there's an issue of some kind with z-buffering. 12-15 fps if that matters at all in this case.

Minecraft Alpha 1.0.4: Crashes on game launch.

Minecraft Beta 1.7.3: Renders an inverted vignette that slowly grows darker.

Minecraft Beta 1.7.3 w/Optifine: Crashes on world load.

Minecraft Release 1.5.2: Rendered the title screen with many errors for a brief moment before turning to a black screen and crashing.

Tux Racer: Unknown; renders mostly a white screen. The game does respond to user inputs, and the rendered scene changes based on those inputs, but no textures or complex objects are ever rendered. Instead, you only get the white "floor" plane, a solid blue skybox, and translucent boxes where text, objects, and particles should've been.

Half Life: Crash on game launch; absolutely RAVAGES the title screen in ways I thought only the Alliance AT3D could.

GL Excess: Actually loads! But renders only solid black or white screens after the initial loading screen.

Techland D3D

Two more wrappers left after this one! This wrapper and the Techland S3D wrapper that came before it were both created by Techland originally for their "Crime Cities" game, which, being an OpenGL title during an era where support was spotty at best across the dozens of vendors that existed at the time, necessitated the creation of a set of OpenGL wrappers that could translate calls to other APIs.

Anyway, I originally thought that there wasn't going to be much that'd be interesting about this wrapper based on how Minecraft (didn't) work, but I was quickly proven wrong in the things I tested afterwards!

Vendor: Techland Renderer: Direct3D (display, Primary Display Driver) KNI Version: 1.1 beta 6

Performance

GLGears: ~290 FPS, but only because a black screen is rendered.

ClassiCube 1.3.5/1.3.6: 2-5 FPS. Runs with z-buffering issues. Faster than software rendering, but not by much (SW rendering was roughly 1-3 FPS)

Minecraft: Renders only a black screen and (usually) crashes.

Tux Racer: Unknown; renders a mostly-white screen. However, shading works well enough that you can just barely distinguish what is what.

Half Life: Crash on game loading after the title screen; absolutely RAVAGES the title screen in ways I thought only the Alliance AT3D could.

GL Excess: Actually runs! Performance is alright in some parts but generally remains low. Also, it erroneously uses the exact same texture for every single rendered object.

S3Mesa/AltOGL

So, it turns out that there may or may not be some level of bugginess involved with S3Mesa and AltOGL on my current testing setup. Whereas both wrappers were (somewhat) stable and able to load into both Minecraft and Half Life with relatively little trouble in previous experiments with AltOGL/S3Mesa and the Virge, this time around it doesn't appear to be working as expected. There may be something that got screwed up thanks to having installed and used multiple different versions of GLDirect prior to using S3Mesa and AltOGL.

The best-case scenario would have been to start off with a fresh install of Windows 98 with every test run with a different wrapper, but in this case I didn't do that. As a result, the findings for S3Mesa and AltOGL here should be considered with a grain of salt.

Vendor: Brian Paul Renderer: Mesa S3GL V0.1 Version: 1.1 Mesa 2.6

Vendor: Brian Paul Renderer: altD3D Version: 1.2 Mesa 3.0

Performance - AltOGL

GLGears: 125 fps

ClassiCube 1.3.5/1.3.6: crash + system lockup

Minecraft in-20091223-1459: crashes on world load (normally it's much more stable according to previous videos. See here for reference: Indev on S3 ViRGE using AltOGL

Minecraft: Aside from Beta 1.7.3 with Optifine which crashes on world load, all versions of the game crash instantly.

Tux Racer: Freezes on main menu

Half Life: Instacrash

GL Excess: Instacrash

Performance - S3Mesa

GLGears: i forgor to run it 💀

ClassiCube 1.3.5/1.3.6: no crash but everything is rendered in solid white rather than with textures. performance is likely in the single digits.

Minecraft in-20091223-1459: crashes on world load (normally it's much more stable according to previous videos. See here for reference: Indev on S3 ViRGE using S3Mesa

Minecraft: Aside from Beta 1.7.3 with Optifine which crashes on world load, all versions of the game crash instantly.

Tux Racer: Renders just about everything except for the game terrain and player character. Performance seems to just barely reach double-digits.

Half Life: Instacrash; textures missing on main menu (similarly to Minecraft indev, this is an unexpected result as the game normally is able to play.)

GL Excess: Instacrash

Misc Notes

Running HWinfo32 crashes the system regardless of if KernelEX is enabled or not.

GLDirect 5 refuses to do anything other than software rendering due to the lack of higher DirectX support by the Virge.

GLDirect 3 can "run", but crashes the entire system after a few seconds in Classicube using the "game" wrapper.

GLDirect 3, unlike 5, has no license code available for free use.

I didn't have the opportunity to record during the time GLDirect 3's trial was active, and it expired already so to avoid having to reinstall everything to get a new trial (I've already tried to roll back the system calendar), I will instead be using GLDirect 2, which I have in fact found a license code for.

GLDirect 2 has a fourth option for OpenGL acceleration beyond the CAD/Game DirectX hardware acceleration and the CPU software acceleration, which is a DX8-based wrapper that appears to have later debuted fully in GLDirect 3.x and up. I think it's safe to assume that the CAD/Game DX6-based wrappers were then deprecated and received no further development after GLDirect 2.x given the pivot to a newer DirectX API.

There are a number of other wrappers available for the S3 ViRGE, and even an OpenGL MCD for Windows 2000. However, I'm sticking with the five that were listed here as they implement enough of the OpenGL spec to be (more) widely compatible with a number of games. The S3Quake wrapper, for example, implements only enough of the spec to run GLQuake, and I have never gotten it to even launch any other titles.

I really, sincerely didn't expect MC Beta 1.7.3 to launch at all even with Optifine, given how from prior testing I found that the game would instantly crash on anything higher than Classi--nevermind, it just crashed on world-load. (S3Mesa, AltOGL, TechlandD3D, TechlandS3D, GLDirect 1.x)

Non-Optifine Beta 1.7.3 crashes before even hitting the Mojang splash screen. (S3Mesa, AltOGL, TechlandD3D, GLDirect 1.x)

Non-Optifine Beta 1.7.3 gets into a world! All text is missing though as are the blocks. Performance is expectedly horrendous. (TechlandS3D)

Making batch files to handle version-switching instead of doing it by hand is nice.

Alongside the system setup for testing apparently no longer being ideal for using S3Mesa and AltOGL, comparison against some test runs done on an Athlon XP 1.1GHz system also reveal that the Virge performs far better with a faster CPU like the aforementioned Athlon XP than the 750MHz Pentium that this series of experiments is built upon. This experiment as a result may be eventually redone in the future using that faster CPU.

Switcharoo! The Java Switch Statement

In Java, a switch statement can examine possible values for a single variable and either make assignments or perform actions based upon that variable's value. #java #syntax #switch

💚 TIP: References Quick List Java Switch Statement Java Switch Expressions In Java, another way that conditions can be checked is with a switch statement. This time, we want to check equality against one variable and the cases we want to test are possible values for that one variable. This works for primitive data types, wrapper classes for primitive data types, and Strings (Java 7+) and…
