public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        // returns the Class object for this class
        Class myClass = Class.forName("Test");
 
        System.out.println("Class represented by myClass: "
                           + myClass.toString());
 
        // Get the enclosing class of myClass
        // using getEnclosingClass() method
        System.out.println("EnclosingClass of myClass: "
                           + myClass.getEnclosingClass());
    }
}

    public static void main(String[] args)
        throws ClassNotFoundException
    {
        Main t = new Main();
 
        // returns the Class object
        Class myClass = t.obj.getClass();
 
        // Get the enclosing class of myClass
        // using getEnclosingClass() method
        System.out.println("EnclosingClass of myClass: "
                           + myClass.getEnclosingClass());
    }
