Java Method Overloading - If a class of a Java program has a plural number of methods, and all of them have the same name but different parameters (with a change in type or number of arguments), and programmers can use them to perform a similar form of functions, then it is known as method overloading.

Take breaks when … Java is an object oriented language and some concepts may be new. Characteristics of Java Constructors An interface cannot have the constructor.

Another important point to note while overloading a constructor is: When we don’t implement any constructor, the java compiler inserts the default constructor into our code during compilation, however if we implement any constructor then compiler doesn’t do it. The constructor in Java cannot be abstract, static, final or synchronized and these modifiers are not allowed for the constructor. Java Polymorphism - The word polymorphism means having multiple forms. See the example below.

The term Polymorphism gets derived from the Greek word where 'poly' + 'morphos' where … The constructor() method is a special method for creating and initializing objects created within a class. Note that the constructor name must match the class name, and it cannot have a return type (like void).. Also note that the constructor is called when the object is created. All classes have constructors by default: if you do not create a class constructor yourself, Java creates one for you.

Constructor Overloading in Java Prerequisite – Constructor , Overloading in java In addition to overloading methods, we can also overload constructors in java. We recommend reading this tutorial, in the sequence listed in the left menu. The constructor() method is called automatically when a class is initiated, and it has to have the exact name "constructor", in fact, if you do not have a constructor method, JavaScript will add an invisible and empty constructor method.
