Constructor Overloading in java

An interesting feature of the constructor is that a class can have multiple constructors.  This is called Constructor Overloading.  All the constructors have the same name as corresponding to the class name that they are differ only interms of their signature as number of arguments or datatypes or order.

Example:

class Time1

{

            int hour,min,sec;

            public Time1()

            {

            hour=0;

            min=0;

            sec=0;

            }

            public Time1(int h)

            {

            hour=h;

            min=0;

            sec=0;

            }

            public Time1(int h, int m)

            {

            hour=h;

            min=m;

            sec=0;

            }

            public Time1(int h,int m,int s)

            {

            hour=h;

            min=m;

            sec=s;

            }

            void printdata()

            {

            System.out.println(hour+"hours:"+min+"minute:"+sec+"sec");

            }

}

class const3

{

            public static void main(String[] args)

            {

                        Time1 t=new Time1();

                        t.printdata();

                        Time1 t1=new Time1(9);

                        t1.printdata();

                        Time1 t2=new Time1(7,8);

                        t2.printdata();

                        Time1 t3=new Time1(10,9,4);

                        t3.printdata();

            }

}
