Using Java Graphics:

Create a pine tree.

has 4 parameters: x, y, width, and height.

The x and y values stored are the upper-left corner of an invisible box that bounds the tree. The width and height are of that invisible box.

The width of the trunk is 1/3 of the width of the box and its height is 1/3 the height of the box.

The height of the branches (the triangle) are 2/3 of the height of the tree and they take up the whole width of the tree.
