 Area(Integer.parseInt(s));
String l=JOptionPane.showInputDialog(null, "Enter Length", "Calculate the area of R Rectangle", JOptionPane.PLAIN_MESSAGE);
String w=JOptionPane.showInputDialog(null, "Enter Width", "Calculate the area of R Rectangle", JOptionPane.PLAIN_MESSAGE);
 Area(Integer.parseInt(l),Integer.parseInt(w));
}
 public static void Area(int s)
  {
    JOptionPane.showMessageDialog(null,"Area of S square: " + s*s);
  }
 public static void Area(int l,int w)
  {
    JOptionPane.showMessageDialog(null,"Area of R Rectangle: " + l*w);
  }
