//Title :Archery2 //Name :Abdulla Al-mutawa //Date :09/27/00 //Purpose :We are going to to add new features to the last program // we will add some buttons and text field which mack the // user able to clear the display windows,request the circles // and the checkerboard to be drown and changing the size and // position of the circles and the checker // there is also a button to throw a drats and also will be // printed on the circles // Imported libraries import java.awt.*;
