JAVA CONSTRUCTORS

    A Constructor initializes an object immediately upon creation of an object.

   It has the same name as the class in which it resides and is syntactically similar to a method.

   Constructors have no return type, not even void. This is because the implicit return type of class’ constructor is the class type itself.

Ex:class Myclass {

          int  a;

          int b;

          Myclass() { // default constructor.

                   a=0;

                   b=0;

          }

Myclass(int x,int y) { // parameterized constructor.

                   a=x;

                   b=y;

          }

void Display() { //Method with no parameters.

                   System.out.println (“A= “ +a+ “ B= “+b);

          }

    }

class Mymain {

          public static void main(String args[]) {

                   Myclass c1=newMyclass(); //Calling default constructor

            Myclassc2=new Myclass(10,20);//Calling parameterized                    constructor

                   c1.Display();

                   int sum=c2.sum();

                   System.out.print("\n Sum of Second object is:"+sum);

          }

}

Output: A= 0  B= 0

               Sum of Second object is: 30
