Question

Use the grow() method to modify a rectangle to be twice as large.

I’m not sure if this is correct so if it is wrong please explain and feel free to correct me.

Kim.grow(5,8);
System.out.println(Kim);

Does this mean that my rectangle will now be twice as big if I code it like this or am I missing something?

grow(int 8, int v)….what would v be?..Im guessing h is the height

Answer 1

According to the Javadocs, the grow(int h, int v) method re-sizes your rectangle such that:

..it is h units larger on both the left and right side, and v units
larger at both the top and bottom.

The new Rectangle has (x – h, y – v) as its upper-left corner, width
of (width + 2h), and a height of (height + 2v).

If negative values are supplied for h and v, the size of the Rectangle
decreases accordingly. The grow method will check for integer overflow
and underflow, but does not check whether the resulting values of
width and height grow from negative to non-negative or shrink from
non-negative to negative.

I’m assuming that Kim is an instance of java.awt.Rectangle of dimensions (x, y)
