I have this program:
****************************
class hello
{
   public static void main(String args[])
   {
      System.out.println("Hello World!");
   }
}
****************************
I saved this program to my hard disk as "hello.java", then I run "javac hello.java". After this I use: "java hello"  and I get this message: Exception in thread "main" java.NoClassDefFoundError: hello"

What do I have to add to my program, how do I compile it ???

I am going from the beginning, because it did not work:

1. I have installed Java under my "d:". It looks like "d:\Java"
2. When I compile the "hello.java" I do this:

- I move to the d:\Java folder, so I get this path:

D:\Java\bin>javac d:\Java\programs\hello.java

D:\Java\bin>java -classpath . hello

It doesn't work.

How do I register the path to javac and hava, so I do not have to always type the full path and how do I run this program ???

You need to put the java bin directory on your path. Look up 'Environment variable' in Windows help
