Binding in Java refers to the process of associating a method or function body with a method or function call by the Java Compiler. In simpler words, when a function is called by the Java compiler the task of correctly locating the method for the respective function is binding. Depending on when the compiler is […]

In this post, we will see about "Can we overload main method in java".This is one of the most asked Core java interview questions. Yes, we can overload main method in java but when you run your program, JVM will search for public static void main(String[] args) and execute that method. Overload main method in […]

In this post, we will about Dynamic method dispatch which is also referred as run time polymorphism. Dynamic Method Dispatch Dynamic method dispatch is a technique by which call to a overridden method is resolved at runtime, rather than compile time.When an overridden method is called by a reference, then which version of overridden method […]

No, we can not override static method in java. Static methods are those which can be called without creating object of class,they are class level methods. On other hand,If subclass is having same method signature as base class then it is known as method overriding. Its execution decided at run time. Below are the reasons why […]

In this post, we will see about copy constructor in java. Copy constructor is the constructor which takes parameter as object of same class and copy each field of the class to the new object. Unlike C++, java does not provide default copy contructor. You need to create one, if you want to have copy […]

In this post, we will see about Java default constructor. Default constructor is the no arg constructor which is inserted by compiler unless you provide any other constructor explicitly. You won’t able to see it as it is present in class file rather than source file. Is there any difference between no argument constructor and […]

In this post, we will see about Inheritance in java. It is one of the OOPs principles apart from Abstraction, encapsulation and polymorphism. Introduction The word Inheritance is quite familiar with everyone. In common terms, the word means the bequeathing of property and characteristics from generation to generation. For example, the property or characteristics of […]

Constructor in java is block of code which allows you to create instance of the object. It does not have return type. It has two main points Constructor name should be same as class Constructor should not have any return type else it will be same as method. There are three types of Constructor in Java. […]

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 and method overriding. There are two types of polymorphism in java. Compile time polymorphism. Run […]
