Make sure you're in the directory that contains 'hello.class'.

thanks for the reply

i have got the hello.class in the d:\ drive(root directory) and i am doing java hello from d:\

do i need to set any other parameter

It sounds like you have everything set up properly. Post your entire source code file if it's different from what you posted above.

thanks for the reply

it is exactly the same,

i pasted the code in netbeans and it works fine

[jaeusm]

Do you have a package declaration at the top of your source file?

[rookie1010]

no i dont

the source file reads

public class hello
{
public static void main ( String[] args )
{
System.out.println("Hello World!");
}
}

Your class name should always be capatilized. Your method names can never start with a capital letter, but class names, "Hello" in this case, should always be capitalized. That should solve the CLI NoClassDefFoundError problem.

[jaeusm]

Capitalization is a matter of style only. The compiler does not care if anything at all is capitalized.

As an aside, good programming style (in Java) dictates that you should capitalize the first letter of class names, but not method names or variable names. Regardless, this has nothing to do with actually compiling or executing the program.

jaeusm, I stand corrected. I know from experience that when ever I had that error it had to deal with the lack of capitalization. However, you were right, according to the documentation for java, you are not required to capatilize class names.
