Java

Java is a versatile, object-oriented programming language known for its "Write Once, Run Anywhere" capability through its platform-independent bytecode.

Install Java

Launch terminal on your Comet or connect via SSH and run the below command.

$ sudo apt update
$ sudo apt install default-jdk

After installation, verify that Java is properly installed:

$ java -version
$ javac -version

Running an example

Let's create a simple "Hello, World!" program to test Golang on the Comet.

1

Create a new directory, and a new source file for your go program.

$ mkdir hello_world && cd hello_world
$ nano HelloWorld.java

2

Paste the following program in the editor

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

3

Now lets compile and run the program.

$ javac HelloWorld.java
$ java HelloWorld
Hello, Java!

Now with java installed, you are ready for compiling and running Java programs ☕️!
