Q:- wap to find the Area and Perimeter of Rectangle ?
ReplyDeleteSolution:-
class Area
{
private int l,b;
public void getdata(int x, int y)
{l=x;
b=y;}
public void showdata1()
{ int p;
p=l*b;
System.out.println("Area of Rectangle is " +p);}
public void showdata2()
{ int q;
q=2*(l+b);
System.out.println("Perimeter of Rectangle is "+q);}
public static void main(String args[])
{Area A1 = new Area();
Area A2 = new Area();
A1.getdata(2,50);
A1.showdata1();
A2.getdata(2,50);
A2.showdata2();}
