Wrong result from Rectangle.contains() in java

Question

It appears that the contains() method in Rectangle is not inclusive to the bottom right corner.

For example the following code returns "false";

Rectangle r = new Rectangle(0,0,100,100);
System.out.println(r.contains(100, 100));

Answer 1

It seems that the API wrongly states that the "upper left corner" is (x,y) when according to the accepted answer and my own experience, (x,y) is the lower left corner.
