Problem executing java programs


I have been searching all over the net for the past few hours trying to find a solution to this horrible problem.
I have a simple program:

Code:
class Test {
  int number=0;
  
  public static void main(String args[]) {
    Test t = new Test();
    System.out.println(t.number);
  }
}
Here was my first method of compilation/execution:
I simply used the Java SDK.

[mike@localhost Java]$ javac test.java
[mike@localhost Java]$ java test
Exception in thread "main" java.lang.NoClassDefFoundError: test

There is the problem: "Exception in thread "main" java.lang.NoClassDefFoundError: test"

I am able to successfully compile the java file, but when it comes to executing it, it gives me trouble. I have tried other simple programs(such as the basic HelloWorld) and they all give me the same trouble.

My second method of compilation/execution:
I downloaded NetBeans IDE 3.6.

I created a project file and used the same code from above. The compilation went smooth, but once again, I got that error.

I have read in other places that I'm missing the classpath, but I'm unsure which .jar file I should be looking for.

Any help is always appreciated.

Thanks,
Mike

You are using "test.java" as file name and "Test" as the class name (note that Java is case sensitive). So you have to use the same main class as the name of the source file....
