Polymorphism is one of theOOPsfeature that allows us to perform a single action in different ways. For example, lets say we have a classAnimalthat has a methodsound(). Since this is a generic class so we can’t give it a implementation like: Roar, Meow, Oink etc. We had to give a...
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...
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: Encapsulation is a process of hiding the...
In above example all the three variables (or data fields) are private(see:Access Modifiers in Java) which cannot be accessed directly. These fields can be accessed via public methods only. VariablesempName,ssnandempAgeare made hidden data fields using encapsulation technique of OOPs. Advantages of...

In order to create an InputStream, we must import the java.io.InputStream package first. Once we import the package, here is how we can create the input stream. // Creates an InputStream InputStream object1 = new FileInputStream(); Here, we have created an input stream using FileInpu...
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...

Below is the some major important points of abstraction in java. Abstraction helps to reduce the complexity and also improves the maintainability of the system. Abstraction gives more power to the object oriented programming languages when used with the concepts like encapsulation and polymorphism. ...
