How to run java program

Run and Compile java code

Write the Java code in a text editor or an integrated development environment (IDE) such as Eclipse, IntelliJ, or NetBeans.
Note:(if you are new programmer and bigger, I suggest to start with notepad)
Example program:

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


Save Save the file with a .java extension. For example, if your program is named HelloWorld, you should save it as HelloWorld.java.

Open a command prompt (Windows) or terminal (Mac/Linux) and navigate to the directory where your Java file is located using the cd command. For example, if your file is located in the Desktop directory, you can navigate to it using the following command:
