My First Java Program: A Journey into Coding

Starting with Java programming can be an exciting journey, filled with discovery, challenges, and a sense of accomplishment. My experience of writing my first Java program was a significant milestone that opened up a world of possibilities in software development. In this blog, I’ll share my journey through writing my first Java program, along with the concepts I learned and the obstacles I overcame.

The Excitement of Starting

When I first decided to learn Java, I was motivated by its versatility and widespread use in developing applications, from mobile apps to enterprise software. I had heard about the power of Java and how it is a foundational language for many developers. After setting up my Java development environment, which included installing the Java Development Kit (JDK) and choosing an Integrated Development Environment (IDE) like Eclipse, I was ready to dive in.

The anticipation of writing my first program filled me with excitement. I had heard many experienced programmers talk about how exhilarating it felt to see their code come to life, and I was eager to experience that feeling myself.

Setting Up the Development Environment

Before I could write my first program, I needed to ensure my development environment was properly configured. Here’s a brief overview of how I set it up:

1. Installing the JDK: I downloaded the latest version of the Java Development Kit from the Oracle website. This included everything I needed to compile and run Java applications.

2. Choosing an IDE: I chose Eclipse as my IDE because of its robust features and user-friendly interface. After downloading and installing it, I was ready to start coding.

3. Verifying the Installation: I opened the command prompt (or terminal) and typed java -version to confirm that Java was installed correctly. Seeing the version number displayed confirmed that I was on the right track.

Writing My First Java Program

With my development environment set up, I was finally ready to write my first Java program. Following the traditional approach, I decided to create a simple “Hello, World!” program. This classic exercise is often the first step for beginners learning any programming language.

Step 1: Creating a New Java Project

In Eclipse, I created a new Java project:

1. File > New > Java Project.

2. I named the project “HelloWorld” and clicked Finish.

Step 2: Creating a New Java Class

Next, I created a new Java class within the project:

1. Right-click on the src folder in the HelloWorld project.

2. Selected New > Class.

3. I named the class HelloWorld and checked the box to include the public static void main(String[] args) method. This method is the entry point of any Java application.

Step 3: Writing the Code

With the class created, I wrote the code that would print “Hello, World!” to the console:

public class HelloWorld {     public static void main(String[] args) {         System.out.println(“Hello, World!”);     } }

Code Explanation

public class HelloWorld: This line defines a public class named HelloWorld. In Java, every application must have at least one class.

public static void main(String[] args): This line declares the main method, which is the starting point of any Java program. The JVM (Java Virtual Machine) looks for this method when executing the program.

System.out.println(“Hello, World!”);: This line prints the string “Hello, World!” to the console. The System.out object is used to output data to the console, and println is a method that prints the text followed by a newline.

Step 4: Running the Program

After writing the code, it was time to run my program and see the result:

1. I right-clicked on the HelloWorld.java file in the Project Explorer.

2. Selected Run As > Java Application.

To my delight, the console displayed the message “Hello, World!” It was a simple program, but seeing the output felt like a monumental achievement. I had successfully written and executed my first Java program!

Learning from the Experience

The process of writing my first Java program taught me several important lessons:

Understanding Java Syntax

Java has a specific syntax that must be followed. This includes rules about naming conventions, the use of semicolons to end statements, and the structure of classes and methods. Understanding these rules is essential for writing valid Java code.

The Importance of the Main Method

The main method is crucial in Java applications. It serves as the entry point, and every program must have it to be executed. Learning this concept helped me appreciate how Java applications are structured.

The Power of Output Statements

Using System.out.println() was my first experience with output statements. It highlighted the importance of feedback in programming. Being able to print messages to the console is invaluable for debugging and understanding program flow.

Overcoming Challenges

While writing my first Java program was largely straightforward, I faced some challenges along the way:

Syntax Errors

Initially, I encountered syntax errors due to missing semicolons or misnamed classes. Each error message provided insight into what I needed to correct. This experience emphasized the importance of careful coding and attention to detail.

Understanding the IDE

Familiarizing myself with Eclipse took some time. I had to learn how to navigate the interface, manage projects, and use features like code suggestions and debugging tools. As I continued coding, I became more comfortable with the IDE.

Next Steps in My Java Journey

Completing my first Java program was just the beginning. With a foundational understanding of Java syntax and structure, I was excited to explore more advanced concepts. Here are the next steps I took in my learning journey:

Exploring Java Basics

I delved deeper into Java basics, including:

Data Types: Understanding primitive and reference data types.

Variables: Learning how to declare and use variables effectively.

Operators: Exploring arithmetic, relational, and logical operators.

Control Flow Statements: Mastering if-else, switch, and loop constructs.

Learning Object-Oriented Programming (OOP)

Java is an object-oriented programming language, and I knew I had to understand OOP principles. I focused on concepts such as:

Classes and Objects: Learning how to create and manipulate objects.

Inheritance: Understanding how classes can inherit properties from other classes.

Encapsulation: Learning how to hide data within classes.

Polymorphism: Exploring method overloading and overriding.

Building Projects

I started working on small projects to apply my knowledge. Simple applications, like a calculator or a text-based game, helped solidify my understanding of Java concepts.

Conclusion

Writing my first Java program was a thrilling experience that marked the beginning of my journey as a programmer. The excitement of seeing my code come to life, coupled with the knowledge I gained, fueled my desire to continue learning and growing in the field of software development.

Java has proven to be a powerful language with endless possibilities, and I am eager to explore its depths further. With each program I write, I feel more confident in my coding abilities and more inspired to tackle new challenges.

It's the one year birthday of my Single Player world!

It's all the first java world I've had and the one year of me having java edition so I'm very happy today. Due to still being in school, and other personal issues, I was only able to play for 425 in-game days but I still got a lot done I think. Incoming Minecraft screenshot pile and ramblings under the cut :].

My first picture and (around) my world spawn. I literally didn't have a minecraft skin at this point due to having bought and downloaded the game at 3 am the night before:

Then theres a picute of the mountain from one of the first sunsets that may or may not be my current computer background. fun fact: this mountain is currently being hollowed out for an unknow project. literally started as me needing coal and now im like a third of the way down this thing):

Next is a bunch of current pictures of the world and builds :D

My house and storage building:

A few different different pictures of the village that i've been building for like 6 months (most of this time I was inactive on the world though):

and a picture of some of my starter farms from the top of my house:

And Finally, an overview-ish shot of a lot of the base :] I'm so happy with my little area no matter how unfinished it is!

Now there are a few different areas that I didn't feel right adding to this post (like more farms, the cave systems that look really cool, and my techno memorial for a few examples) so this isn't everything that exists on the world but here is most of it. I'm so attached to this world and enjoy what i've created on it. I'll stop rambling now, if not I could go on forever :].

Overview of My Experience With my Java Project

I have done my course on Java this semester, and at the end we turn in a project we make that is of our choosing. I made a shopping helper application that tracks spending habits and how your recent shopping trips went. It's useful for keeping track of inflation too hehe.

I used an API to fetch the local area tax rate based on US ZIP codes (sorry to everyone outside the US). I also used GSON to write JSON files to save progress, because sometimes we all have to step away right? It also saves the receipt as a .txt or .csv file.

It's in total 3282 lines of code and the sale types was the worst part giving so many errors due to my dumb ass not knowing how to do math, but other than that I honestly just hate UI with a passion, so that wasn't fun.

Overall despite my initial hatred of Java, I think I can safely say while it is annoying, I will probably be okay working with it again. I don't love it or hate it.

Now next semester is when I'll shine. C# should be a breeze, and hopefully I'll learn something new. HTML/CSS should be okay although I'm debating switching it out for .net (don't ask why C# and .net are in 2 different classes, idk either). C++ with Unreal engine will be the scary one for me since I've heard horror stories about C++.

On a small note I hope we use C# 12 and if I do .net I hope it's .net 8
