Can anyone tell me how to combine results of area and perimeter of a rectangle in one JOptionPane?

 

 

 

import javax.swing.JOptionPane;
 
  

     
  void setup(){
  size(480,120);
  background(0);
  noLoop();
}

  void draw(){
  background(0);
      int width;
      int height;
      int length;
      int area;
      int perimeter;
      String heightstr, widthstr;

  heightstr = JOptionPane.showInputDialog("Enter the height: ");
  widthstr = JOptionPane.showInputDialog("Enter the width: ");
     width=parseInt(widthstr);
     height=parseInt(heightstr);
    
      area = width * height;
      perimeter = 2 * height + 2 * width;
     
   
  
 JOptionPane.showMessageDialog(null, area, "Area",  JOptionPane.INFORMATION_MESSAGE);  
 JOptionPane.showMessageDialog(null, perimeter, "Perimeter", JOptionPane.INFORMATION_MESSAGE);
    
 }
