To run a Java program, you first need to install the Java Development Kit (JDK) and set up the environment variables. Then, follow the steps below:

  1. Write a Java program. Create a file with a .java extension using a text editor, such as HelloWorld.java, and write Java code in it.
  2. Compile the Java program. Open the command line interface and compile the Java file using the javac command. For example, running the command javac HelloWorld.java will compile the HelloWorld.java file and generate the corresponding .class file.
  3. Run a Java program. In the command line interface, use the java command to run the compiled Java program. For example, executing the command java HelloWorld will run a Java program named HelloWorld.

Please make sure that you have successfully installed the JDK and set the environment variables correctly in order to run Java programs.
