1.Method Overloading in Java– This is an example of compile time (or static polymorphism) 2.Method Overriding in Java– This is an example of runtime time (or dynamic polymorphism) 3.Types of Polymorphism – Runtime and compile time– This is our next tutorial where we have covered the...
In the above example the call to the disp() method using second object (obj2) is runtime polymorphism (or dynamic method dispatch). Note: In dynamic method dispatch the object can call the overriding methods of child class and all the non-overridden methods of base class but it cannot cal...
The repaint () method causes then AWT runtime system to execute the update () method of the Component class which clears the window with the background color of the applet and then calls the paint () method. But sometimes erasing the background is undesi
3. Polymorphism Polymorphism is the concept where an object behaves differently in different situations. There are two types of polymorphism - compile time polymorphism and runtime polymorphism. Compile-time polymorphism is achieved bymethod overloading. For example, we can have a class as below. p...

creation of back-end class when it’s needed, for example we can changemethod to initialize the Job object at runtime when required. Further Reading: Do you know one of the best practice in java programming is to use composition over inheritance, check out this post for detailed analysis ...

can help a little PS: As forJeff Wilton's answer about instaceOf, yes I myself will not recommend using instanceOf if there is an option using polymorphism. However, inthe real world sometimes you cannot get to choose what kind of data other developers pass to your code. There ...
1. No Runtime Polymorphism First and foremost, the static method reduces the flexibility of your system. Once a method is declaredstatic, it's fixed. You cannot provide an alternate implementation of that method in a subclass, as thestatic method cannot be overridden, they can only be hidden...
