Let's say your file is in C:\mywork\ Run Command Prompt C:> cd \mywork This makes C:\mywork the current directory. C:\mywork> dir This displays the directory contents. You should see filenamehere.java among the files. C:\mywork> set path=%path%;C:\Program Files\Java\jdk1.5.0_09\bin This tells the system where to find JDK programs. C:\mywork> javac filenamehere.java This runs javac.exe, the compiler. You should see nothing but the next system prompt... C:\mywork> dir javac has created the filenamehere.class file. You should see filenamehere.java and filenamehere.class among the files. C:\mywork> java filenamehere This runs the Java interpreter. You should then see your program output. If the system cannot find javac, check the set path command. If javac runs but you get errors, check your Java text. If the program compiles but you get an exception, check the spelling and capitalization in the file name and the class name and the java HelloWorld command. Java is case-sensitive! read less
