Problem about using reflection

Question

//this code works fine
Method method = label.getClass().getMethod( "setToolTipText", new Class[]{String.class} );
method.invoke( label, new Object[]{"message"} );
//but this code doesnot work, give me error "NoSuchMenthodException : addMouseListener
Method method = label.getClass().getMethod( "addMouseListener", new Class[]{MyMouseListener.class} );
method.invoke( label, new Object[]{myMouseListener} );
** MyMouseListener extends MouseAdapter

Answer 1

Should work ok:
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class Test {
     static class MyObject {}
     public static void main(String[] args) throws Exception {
          Class c = Test.class;
          Class[] parameterTypes = new Class[] {Integer.class, MyObject.class};                              
          try {
               Object[] arguments = new Object[] {new Integer(2), new MyObject()};
               Method met = c.getMethod("myMethod", parameterTypes);
               met.invoke(new Test(), arguments);
          } catch (NoSuchMethodException e) {
               System.out.println(e);
          } catch (IllegalAccessException e) {
                 System.out.println(e);
          } catch (InvocationTargetException e) {
               System.out.println(e);
     public void myMethod(Integer var1, MyObject mobj) {
          System.out.println("myMethod");
}
