While many programming environments will allow you to compile and run a program within the environment, you can also compile and run using Command Prompt. Both Windows and Mac have their own versions of Command Prompt, although it is technically called Terminal on the Mac OS. The process is essentially identical for Windows and Mac.

Compiling and Running

• To ensure that your file is saved as a .java file, be sure to write .java after the file name, and select All Files from the dropdown extension menu.
• Make note of where you saved the file on your system.
• If you are unsure of how to write a program in Java, check out our tutorial on how to program in Java. For the purposes of learning how to compile and run a program, though, you can use any sort of Java program.

• Windows: Press ⇱ Home , then type cmd. Press ↵ Enter to open the Command Prompt.
• Mac: In Finder, press the Go tab, select Applications, select Utilities, then select Terminal.

• If not, you may need to install the Java Development Kit from their website. It is free and can be found at this link: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

• For example, if you were operating in C:\Users\Bob\Project and wanted to get to C:\Users\Bob\Project\TitanProject , enter in cd TitanProject and press ↵ Enter .
• You can see a list of what is in your current directory by typing dir and pressing ↵ Enter .

• If you have any errors in your program, or if there is difficultly compiling, the command prompt will notify you.
• Check out our article about how to fix compiler errors in Java for more help.

• After pressing ↵ Enter , your program should run. If you receive an error, or if your program fails to run in any way, refer to the troubleshooting method.

Troubleshooting

• Windows: Type java -version into the command prompt and press ↵ Enter . Based off the version of Java displayed on the first line, type in set path=%path%;C:\Program Files\Java\jdk1.5.0_09\bin to the command prompt and press ↵ Enter . Substitute jdk1.5.0_09 with whatever version of Java you have installed.
  • Be sure you are entering in this command while in the directory containing your Java project.

  Once you are in the correct directory, you can compile the program by typing «javac filename.java» into the command line and pressing enter.
