running a java program typically involves compiling the java source code into bytecode and then executing that bytecode using the java virtual machine (jvm). in this tutorial, we'll cover how to create a simple java program, compile it, and run it as an executable jar file.

step 1: install java development kit (jdk)

before you can run java programs, you need to have the jdk installed on your machine. you can download the jdk from the [oracle website](https://www.oracle.com/java/technolog...) or use a package manager appropriate for your operating system.

to verify that you have java installed, open a command prompt or terminal and run:



step 2: write a simple java program

create a new file called `helloworld.java` and add the following code:



step 3: compile the java program

to compile the java program, open your command prompt or terminal, navigate to the directory where `helloworld.java` is located, and run:



this command will generate a file called `helloworld.class`. this `.class` file contains the bytecode that the jvm can execute.

step 4: run the java program

you can run the compiled java program using the following command:



you should see the output:



step 5: create an executable jar file

to create an executable jar file, you need to package your `.class` files and a manifest file. the manifest file tells the jvm which class contains the `main` method to run.

1. **create a manifest file**: create a text file named `manifest.txt` with the following content:



make sure there is a newline at the end of the file.

2. **create the jar file**: run the following command to create the jar file:



this command creates a jar file named `helloworld.jar` that includes the manifest and the compiled class file.

step 6: run the jar file

you can run the jar file using the following command:



you should see the output:
