How to Write a Java Application
Java is an object-oriented programming language. It is easy to learn and is used for developing applications. The language is also very platform-independent. This makes it easy to run Java programs on different computers.
Object-oriented programming means that the code is structured in sections called "classes." Classes provide a coherent experience. They help keep the code organized and make it simple to modify.
In order to write a Java program, you need to have the JRE (Java Runtime Environment) installed. You can download the latest version for your system from the official Oracle website.
After installing the JRE, you should launch the IDE and set up the environment. To do this, go to your Task Bar and find the Environment Variables menu. Click Edit to set up the necessary environment variables.
Next, you need to create a new Java class. Creating a new class involves giving the name to the class.
For example, if you are creating a media playing software, you would call the class Hello. If the class is a public one, you could use the access modifier public.
Java programs are written in modular blocks of code called classes. This structure ensures that the code is organized and versatile.
When you are writing a Java program, you need to put a curly bracket "" after the class. This means that the Java code will close when the class is closed.
Variables are essential to a Java program. Each variable is a container for data. These can be floats, decimals, strings or any other type of data.
