Program:
class Area
{
   int a,b;
   void area(int a)
   {
     double A=3.14*a*a;
     System.out.print("\n\tArea of circle="+A);
   }
   void area(int a,int b)
   {
     double B=a*b;
     System.out.print("\n\tArea of Rectangle="+B);
   }
}
class methodoverload
{
  public static void main(String args[])
   {
     Area A1=new Area();
     A1.area(10);
     A1.area(5,10);
   }
}
