Q) Example program on zero argument constructor implementation?

A)

//default constructor example

class employee

{

       int empno;

       int age;

       float salary;

       employee()

       {

              empno=1001;

              age=35;

              salary=15000;

       }//default constructor

       void displayemployeedetails()

       {

              System.out.println("empno :"+empno);

              System.out.println("age :"+age);

              System.out.println("salary (Rs) :"+salary);

       }//instance method

}//employee data type created(class is user defined data type).

class defaultconstructorexample {

       public static void main(String[] args) {

              employee e = new employee();

              e.displayemployeedetails();

       }

}

Output:
empno :1001

age :35

salary (Rs) :15000.0
