Use instruction cd (short for Change Directory) to navigate to your desktop.

In your terminal, navigate to your HelloWorld.java file.To navigate to your file, you can change directories on your terminal to your desktop where you saved you HelloWorld file. To open your terminal, click on Finder, Applications, Utilities, then click Terminal. You can compile your computer program using your terminal.Your terminal is a device that allows you to communicate with your computer.

Next, compile your program using the java compiler included on Mac OS X operating systems. The indentations are not necessary for the functionality of your program, but they are recommended to make you code more readable. Your program should look similar to the program in the image above. This step concludes the coding portion of the tutorial. Place a semi-colon at the end of your instruction to show that the instruction on that line of code has ended. Inside the braces of the main function in the HelloWorld class, write the instructionīe sure the words that you want the program to print to your console are placed inside quotation marks. Will print the parameter of the instruction to the computer console. For this program, you want the computer to print the words 'Hello World!' to your console. The instructions inside the brackets of the main function will tell your computer what to do when it executes the program.

The final step in writing your code is to define the main function in you HelloWorld class.
