Copy Constructor using Java



Write a program in Java to implement copy Constructor





Program:





class
Rectangle


 {


  float length,breadth;


  Rectangle(float a,float b)


   {


   length=a;


   breadth=b;


   }


  Rectangle(Rectangle obj)


   {


   length=obj.length+5;


   breadth=obj.breadth+5;


   }


  float area()


   {


    return (length*breadth);


   }


 }





 class Sk06


 {


  public static void main(String args[])


   {


    Rectangle ob1=new Rectangle(5.5f,6.5f);


    float ar1=ob1.area();


    System.out.println("Area from
Parameter = "+ar1);





    Rectangle ob2=new Rectangle(ob1);


    float ar2=ob2.area();


    System.out.println("Area from
Object="+ar2);


   }


 }





Compile:


D:\>javac
Sk06.java





Run:


D:\>java
Sk06





Output:


Area from
Parameter = 35.75


Area from
Object = 120.75
