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...
Runtime Polymorphism In this tutorial, we will see about Polymorphism in java. Polymorphism in java is one of core Object oriented programming concepts with Abstraction, encapsulation, and inheritance. Polymorphism means one name many forms. In Java, polymorphism can be achieved by method overloading...
Inheritance in Java sets the parameters of a new class to include at least all the parameters of its parent class. Find out why this differs from...

etc. In order to sort an ArrayList of custom or user-defined objects, you need two things, first a class to provide ordering and a method to provide sorting. If you know about ordering and sorting in Java then you know that theComparableandComparatorclass is used to provide the ordering ...
Method overriding forms Run-time polymorphism. Note: By default functions are not virtual in C# and so you need to write “virtual” explicitly. While by default in Java each function are virtual. Example of Method Overriding: Class parent { virtual void hello() { Console.WriteLine("A D Pat...
In the above examples, java compiler doesn’t know the actual implementation class of Shape that will be used at runtime, hence runtime polymorphism. 4. Inheritance Inheritanceis the object-oriented programming concept where an object is based on another object. Inheritance is the mechanism of co...
Encapsulation With Example And Program In JAVA Encapsulation is one of the four key concepts in OOPS (Object Oriented Programming) namelyInheritance, Encapsulation,Abstractionand Polymorphism. Following definition helps you to understand the concept of encapsulation:...
