Rectangle newRect = new Rectangle(x, y, width, height);
```
The `Rectangle` class supports numerous useful methods.
The `Rectangle` class supports numerous useful methods, including the following:
- `firstRect.intersects(secondRect)` checks if two rectangles intersect.
- `firstRect.union(secondRect)` returns a rectangle representing the union of two rectangles.
- `firstRect.contains(x, y)` checks whether the integer point $(x,y)$ exists in firstRect.
- `firstRect.intersection(secondRect)` returns a rectangle representing the intersection of two rectangles.
- what happens when intersection is empty?
- `firstRect.intersects(secondRect)` checks if two rectangles intersect.
- `firstRect.union(secondRect)` returns a rectangle representing the union of two rectangles.
- `firstRect.contains(x, y)` checks whether the integer point $(x,y)$ exists in firstRect.
- `firstRect.intersection(secondRect)` returns a rectangle representing the intersection of two rectangles.

This class can often lessen the implementation needed in a lot of bronze problems and CodeForces problems.
