Throughout this course, you will be learning about object-oriented programming and demonstrating what you learn by writing some programs in Java. The first step will be to install and integrated development environment (IDE) that will be where you will write and compile your programs. You will also write your first program using Java to show that you have correctly installed the IDE. The project instructions and deliverables are as follows:

In this course, we will explore the principles and concepts of object-oriented programming (OOP) and apply our understanding by writing programs in Java. To begin, we need to set up an integrated development environment (IDE), which will serve as the platform for writing and compiling our programs. Additionally, we will create our first Java program to validate the successful installation of the IDE.

I. Installing the IDE:
1. Research available IDEs that support Java programming.
2. Choose an IDE based on personal preference and requirements.
3. Download the chosen IDE from the official website.
4. Follow the installation instructions provided by the IDE’s documentation.

II. Writing the First Program:
1. Launch the installed IDE.
2. Create a new project with an appropriate name, such as “HelloWorld.”
3. Within the project, create a new Java class named “Main” (or any desired name).
4. Write Java code within the class to display the message “Hello, World!” to the console.
5. Save the file with a “.java” extension, such as “Main.java.”
6. Compile the Java program using the IDE’s compiler.

III. Deliverables:
1. A document specifying the chosen IDE and the reasoning behind its selection.
2. A screenshot of the IDE’s main interface after installation.
3. The complete Java code for the “Hello, World!” program.
4. A screenshot demonstrating the successful compilation and execution of the program.

It is important to understand the rationale behind these instructions. Object-oriented programming is a paradigm that organizes software design around objects, which represent real-world entities or concepts. Java, being an object-oriented programming language, serves as an excellent tool to practice and apply these concepts.

An IDE is a software application that facilitates software development by providing a comprehensive set of tools, such as code editors, debuggers, and compilers. By installing an IDE that supports Java, we can leverage its features to write, test, and debug our programs efficiently.

Before proceeding further, it is essential to consider the available IDE options and make a judicious choice based on personal requirements. Factors to consider may include ease of use, community support, integration with other tools, and personal familiarity. Some renowned Java IDEs include Eclipse, Intellij IDEA, and NetBeans.

Upon selecting an IDE, we need to download the software from the official website. Following the installation instructions provided by the IDE’s documentation ensures accurate installation. It is imperative to install the IDE correctly to ensure a seamless programming experience throughout the course.

Once the IDE is installed, we can move on to writing our first Java program. This program, commonly referred to as the “Hello, World!” program, is a tradition among programmers and serves as a basic introduction to a programming language. By writing this program, we can verify that the IDE is functioning correctly and set up to compile and run Java code.

To create the program, we must first launch the installed IDE. Then, we create a new project, typically found under the “File” or “Project” menu. Naming the project appropriately, such as “HelloWorld,” helps maintain organization as we progress through the course.

Within the newly created project, we create a new Java class. The class serves as a blueprint or template for creating objects. Naming the class “Main” or a similar descriptive name is recommended to indicate its purpose. It is worth noting that Java requires that the class name matches the name of the Java file.

Inside the class, we write the Java code to display the message “Hello, World!” to the console. This can be achieved by using the “System.out.println()” statement, where “System” is a class provided by Java and “out” is a static field that refers to the standard output stream (the console). The method “println()” is then called to print the specified message within the parentheses.

Once the Java code is written, we save the file with a “.java” extension. The IDE ensures that the file is saved in the appropriate location within the project structure.

After saving the file, we can compile the Java program using the IDE’s compiler. The compiler translates the human-readable Java code into machine-executable instructions. The IDE typically provides a button or a toolbar option to initiate the compilation process.

Upon successful compilation, the IDE will generate a bytecode file (with a “.class” extension) that can be executed by the Java Virtual Machine (JVM).
