Mac OS X 10.8 (Mountain Lion) to Mac OS X 10.13 (High Sierra). It also provides a step-by-step guide for creating,Ĭompiling, and executing a Java program using either DrJava or the Terminal.Īll of the software used is freely available.
This document instructs you on how to set up our Java programming environmentįor your Mac OS X computer. It has been replaced by the following IntelliJ-based programming environment for (because DrJava in no longer being actively developed and DrJava is incompatible with Java 11). If there are any errors in your code, the compiler will point them out to you on your terminal.This DrJava-based Java programming environment is no longer being supported
This will create an additional executable file on your desktop that your computer can run. Compiling your program will convert the code in you HelloWord java file to language the computer can read. You can now compile your HelloWorld program. 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.
