class not found in java reflection

I'm learning java reflection. I am using the following code. But when I run, it gives the error unreported exception ClassNotFoundException; must be caught or declared to be thrown Class className=Class.forName("First"); Maybe I'm going wrong somewhere. Please help me out. Here's the code:

import java.lang.reflect.Method;
public class First{   
        public void print(){}
        public void ready(){}
    }

public class test{
    public static void main(String args[])
    {
        Class className=Class.forName("com.Test.First");
        Method[] methods=className.getMethods();
        System.out.println("First method is" + methods[0]);
    }
}
