Open the terminal and type nano Yowza.jsh.

TYPE in the following text:

System.out.println("Yowza!");
int i = 42;
System.out.println(i);
double d = 2.71828;
System.out.println(d);
String s = "ZipCode Rocks!";
System.out.println(s);

Save the file. Exit the editor.

# run this in a terminal
jshell Yowza.jsh

In the terminal and type nano Hello.java.

TYPE in the following text:

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

Save the file. Exit the editor

• Compile the file using javac Hello.java
• Run the program using java Hello

What happened? Did you see the output Hello, Java!?

Now, let's try something else.

Edit Hello.java using nano.

Add the following line of code:

System.out.println("Hello, again!");

Make sure you put it inside the main method, right after the Hello, Java line. Save the file. Exit the editor.

Compile and run the program again.

What happened? Did you see the output Hello, Java! and Hello, again!?

Good. Now save all this to your GitHub repository.

git add .
git commit -m "Add Hello Java work, finished"
git push
