1). When you start it, it will display the first tree in the screen[a small bug: the tree will be displayed, then clear, then be displayed again.] 2). Keyboard events “a”, “b”, “c”, “d”, “e” displays the 5 trees respectively. 3). Keyboard events “r” displays a random tree. 4). Keyboard events “f” displays my park with two cars(one for adult, and one for child). 5). ATTENTION: I draw 13 trees in my park, so it will cost about 5 seconds, please be patient. Thanks! :-) 6).
