Question

Hello everyone

I need to do a code that check if two rectangles are overlapping in Java.

So I have Rectangle 1 = x,y,width, depth.

And Rectangle 2 = x,y,width,depth

So how do I calculate that?

Thank you,

class Point {

   int x, y;
}

class OverLap {
   static boolean isOverlaping(Point l1, Point rect1, Point l2, Point rect2) {
       // If one rectangle is on left side of other
       if (l1.x > rect2.x || l2.x > rect1.x) {
           return false;
       }
       // If one rectangle is above other
       if (l1.y < rect2.y || l2.y < rect1.y) {
           return false;
       }
       return true;
   }

   public static void main(String[] args) {
       Point l1 = new Point();
       Point r1 = new Point();
       Point l2 = new Point();
       Point r2 = new Point();
       l1.x = 0;
       l1.y = 10;
       r1.x = 10;
       r1.y = 0;
       l2.x = 5;
       l2.y = 5;
       r2.x = 15;
       r2.y = 0;

       if (isOverlaping(l1, r1, l2, r2)) {
           System.out.println("Rectangles Overlap with each other");
       } else {
           System.out.println("Rectangles Don't Overlap with each other");
       }
   }
}
