checking if a point is inside a specified Rectangle?

Question

ok, so i'm doing an assignment for a Java class and one part of the assignment is to find out if a point is within the dimensions of a rectangle. so I created this code: public boolean contains(Point p){ return (this.getLocation().getX() < p.getX() && this.getLocation().getY() < p.getY() && this.getLocation().getX() + this.getWidth() > p.getX() && this.getLocation().getY() + this.getHeight() > p.getY()); } I created a point class as well, which is why I asked for a "Point p" parameter. To test this boolean I created a simple 'if' statement in my Main class: //check if one rectangle's point is inside another if (rectangle.contains(rectangle2.getLocation())) System.out.println("the point is in the rectangle"); The location of the point is (6,7). The point, width, and height of rectangle 1 is (4,5), 9, and 3, respectively. I know for a fact that this point is inside the first rectangle, but the println statement is not showing, meaning there must be a problem with the boolean i created but I don't see an error, maybe my head is cloudy but can someone point out to me what's wrong here? P.S. this is all Console work, i'm not dealing with some GUI or graphics programming.

Answer 1

I am confused by the input. You are saying the top left of the rectangle is (4,5) having length 9 and width 3.

Then the other three corners are (13,5) (1,5) and (1,13)

(6,7) is NOT inside that rectangle, so your result is correct.

If this is incorrect, please explain the input, how the rectangle is supposed to be represented.

Typically you input the TOP LEFT corner with the length and width. The other three corners can

be calculated as above. You can then determine if the given point is on or inside the rectangle.
