// Java program to check if rectangles overlap  
class GFG {
 
   static class Point {
 
        int x, y;
    }
 
// Returns true if two rectangles (l1, r1) and (l2, r2) overlap
 static  boolean doOverlap(Point l1, Point r1, Point l2, Point r2) {
        // if rectangle has area 0, no overlap
        if (l1.x == r1.x || l1.y == r1.y || r2.x == l2.x || l2.y == r2.y)
            return false;
     
           // If one rectangle is on left side of other
        if (l1.x > r2.x || l2.x > r1.x) {
            return false;
        }
 
        // If one rectangle is above other
        if (r1.y > l2.y || r2.y > l1.y) {
            return false;
        }
 
        return true;
    }

        if (doOverlap(l1, r1, l2, r2)) {
