Key stroke enacted moving of a ball 1. Start (a) Write a Java program that uses the Up, ↑, Down ↓, Right ⇒ (and possibly Left) arrows of the keyboard (or keypad) to move a ball. (note the Up arrow is called "Up" with ASCII code 38, Down arrow is called "Down" with ASCII code 40, Right arrow is called "Right" with ASCII code. You can also use the 4 keys, commonly used in ODS game programming. Start Pond Figure 1. Initially Pond End End Start Pond Start Figure 2. After 3 moves up using up arrow End Pond End Figure 3. 3 moves later with right arrows Figure 4. Finally one at the lower right corner. (b) Using Java class JFrame to draw a grid of 5 horizontal lines, 5 vertical lines, a blue pond in the middle occupying 5 squares with a text Pond in the middle, a ball at the lower left corner, and texts called Start and End. This is shown exactly as in Figure 1 here. Change the color of ball from green to another color.
