Java, renowned for its simplicity, reliability, and portability, has been a cornerstone in the programming landscape for decades, largely due to its effective use of OOP (Object-Oriented Programming) concepts. The inception of Java, with its oops concepts in java, reshaped how developers approache...
OOPS Concept in Java In this post, we learn OOPs Concept in Java. OOPS Stands for Object Oriented Programming System. In this tutorial, I will introduce you to Class, Object, Constructor, Abstraction, Encapsulation, Inheritance, Polymorphism, Interface etc., Class: A class is a blueprint or ...
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...
Java SwingandAwtclasses represent best examples for inheritance. Polymorphism This post provides the theoretical explanation of polymorphism with real-life examples. For detailed explanation on this topic with java programs referpolymorphism in javaandruntime & compile time polymorphism. Polymorphism means t...

Java OOPs Concepts, OOPs, (Object-Oriented Programming), procedure-oriented vs object-oriented, java oops concept with examples, oops features, object, class, inheritance, polymorphism, abstraction and encapsulation.
Java Examples The following examples show how to use sun.jvm.hotspot.oops.Symbol. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You may check out the related API usage...
Examples of OOPs are C++, Java, C#, .NET, etc.18) What are the differences between error and exception?Basis of ComparisonExceptionError Recoverable/ Irrecoverable Exception can be recovered by using the try-catch block. An error cannot be recovered. Type It can be classified into two categori...
Example of encapsulation: A class in java is a simplest example of encapsulation. It keeps the data(variables) and behavior(methods) of an entity together. A class also restricts access to these data and behavior through the use of access specifiers. The concept of keeping instance variables ...
To see how objects are represented in Java we use a very simple example, an Integer object that holds a primitive int. When you write a simple line of code as below: 1 Integer i =newInteger(23); The compiler allocates much more than 32 bits of heap to this object. ints are 32 bi...
