Running a Java Application Not Coming in Eclipse

To run a Java application outside of Eclipse, you can follow these steps:

1. Compile your Java source code using the javac command. For example, if your application is stored in a file called Main.java, open a terminal or command prompt and execute the command:

   javac Main.java

   This will generate a Main.class file containing the compiled bytecode.

2. Run the compiled bytecode using the java command. In the same terminal or command prompt, execute the command:

   java Main

   This will run the Java application and produce the output, if any.

Make sure you are in the correct directory where your Java source code file is located. If you have multiple classes in your application, remember to compile all the necessary Java files before running the main class.

Here’s an example to further illustrate the process. Let’s say you have a Java application with the following source code in a file called Main.java:

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

Open a terminal or command prompt, navigate to the directory where Main.java is located, and execute the following commands:

javac Main.java

java Main

The output should be:

Hello, World!
