Running a Java Program from Command Prompt ------------------------------ Create a temporary folder C:\mywork. Using Notepad or another text editor, create a small Java file HelloWorld.java with the following text: public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } } Save your file as HelloWorld.java in C:\mywork. To make sure your file name is HeloWorld.java, (not HelloWorld.java.txt), first choose "Save as file type:" All files, then type in the file name HelloWorld.java. Run Command Prompt (found under All Programs/Accessories in the Start menu). Type C:\> cd \mywork This makes C:\mywork the current directory. C:\mywork> dir This displays the directory contents. You should see HelloWorld.java among the files. C:\mywork> set path=%path%;C:\Program Files\Java\jdk1.8.0_51\bin (use the JDK folder for the version installed on your system). This tells the system where to find JDK programs. C:\mywork> javac HelloWorld.java This runs javac.exe, the compiler. You should see nothing but the next system prompt... C:\mywork> dir javac has created the HelloWorld.class file. You should see HelloWorld.java and HelloWorld.class among the files. C:\mywork> java HelloWorld This runs the Java interpreter. You should see the program output: Hello, World! If the system cannot find javac, check the set path command.
