#arrays and collections in java

[frog707]

Those wise, old Javanese

Yesterday I discovered "Arrays of Wisdom of the Ancients", Aleksey Shipilёv's 2016 quest for the most efficient way to convert Java collections into arrays. It's a fascinating story. Aleksey explains why the conversion API is the way it is, then presents some counter-intuitive measurements.

Next he makes an important point about performance analysis:

At this point, most people make the major mistake: they run with these numbers as if they are the truth. But these numbers are just data, they don’t mean anything unless we extract the insights out of them. To do that, we need to see why the numbers are like that.

To gain such insight, Aleksey uses various profiling tools. After pursuing some related questions (which lure him back into the spiderweb-encrusted days of Java 1.6), he concludes by making another point I adore:

most of the time, the straight-forward code is fast enough, so stop philosophizing about angels on the head of a pin, and get back to work. 99.9% of applications do not need a dedicated team of performance engineers; they need instead for their developers to focus on writing clear, maintainable code, and a little bit of measurement and tuning to file off the rough edges when the code fails to meet the performance requirements.

Getting Started with C Programming

1. Setting Up Your Development Environment

To start programming in C, you need to set up a development environment. Here’s how:

Choose a Compiler: Popular C compilers include GCC (GNU Compiler Collection) for Linux and MinGW for Windows. You can also use IDEs like Code::Blocks, Dev-C++, or Visual Studio.

Install the Compiler: Follow the installation instructions for your chosen compiler. Ensure that the compiler is added to your system’s PATH for easy access.

Choose a Text Editor or IDE: You can write C code in any text editor (like Notepad++ or Sublime Text) or use an Integrated Development Environment (IDE) for a more user-friendly experience.

2. Writing Your First C Program

Let’s start with a simple "Hello, World!" program to familiarize you with the syntax:#include <stdio.h> int main() { printf("Hello, World!\n"); return 0; }

Explanation:

#include <stdio.h>: This line includes the standard input-output library, allowing you to use functions like printf.

int main(): This is the main function where the program execution begins.

printf("Hello, World!\n");: This line prints "Hello, World!" to the console.

return 0;: This indicates that the program has executed successfully.

3. Understanding C Syntax and Structure

C has a specific syntax that you need to understand:

Variables and Data Types: C supports various data types, including int, float, char, and double. You must declare variables before using them.

int age = 25; float salary = 50000.50; char grade = 'A';

Operators: C provides arithmetic, relational, logical, and bitwise operators for performing operations on variables.

Control Structures: Learn about conditional statements (if, else, switch) and loops (for, while, do-while) to control the flow of your program.

4. Functions in C

Functions are essential for organizing code and promoting reusability. Here’s how to define and call a function:#include <stdio.h> void greet() { printf("Welcome to C Programming!\n"); } int main() { greet(); // Calling the function return 0; }

5. Arrays and Strings

Arrays are used to store multiple values of the same type, while strings are arrays of characters. Here’s an example:#include <stdio.h> int main() { int numbers[5] = {1, 2, 3, 4, 5}; char name[20] = "John Doe"; printf("First number: %d\n", numbers[0]); printf("Name: %s\n", name); return 0; }

6. Pointers

Pointers are a powerful feature in C that allows you to directly manipulate memory. Understanding pointers is crucial for dynamic memory allocation and data structures.#include <stdio.h> int main() { int num = 10; int *ptr = &num; // Pointer to num printf("Value of num: %d\n", *ptr); // Dereferencing the pointer return 0; }

7. Structures and Unions

Structures allow you to group different data types under a single name, while unions enable you to store different data types in the same memory location.#include <stdio.h> struct Student { char name[50]; int age; }; int main() { struct Student student1 = {"Alice", 20}; printf("Student Name: %s, Age: %d\n", student1.name, student1.age); return 0; }
