Since you have provide parameter to your toString() method, it is no more the Object's class toString() method. It is a new method and works as a overloaded version of Object's toString() not the overridden version. Remove the parameter. To work the toString() properly you need to have the exactly same method signature -

public String toString(){
   //implmentation
}
