    Why did you install netbeans if you want to compile & run from the command prompt?

    What happens when you type 'javac' at the command prompt?

    first change the dir to the location of saved .java file using the cd on your terminal application or command prompt.
    then type javac "asdf.java" whatever, then type java "asdf" and it will run

    Keep the code coming!

    D:\mywork>
    first the HelloWorld needs to be in file of same name, you have Helloword.java should be HelloWorld.java
    once you have renamed it, type at the prompt
    d:\mywork>javac HelloWorld.java
    Java is case sensitive.

    next type: java helloworld
    and you should have it.

    Go in the directory where your jdk is installed.
    Place your .java file in bin folder located inside jdk folder.
    Go to command prompt and move to jdk\bin directory
    And then write javac className.java
    java className

    Or set your environment variables such as JAVA_HOME, CLASSPATH

    Place your .java file in bin folder located inside jdk folder.
    Only for testing. Do not leave any of your files in the JDK folder.
