Distinguish between the terms unique class and connection point. [3 marks] (b) Explain exhaustively what happens when class GPS underneath is launched taking note of, specifically, any tasks that are made. [17 marks] class GPS { public int[][] a = new int[4][4]; private int[] I = new int[1]; private int[] j = new int[1]; public GPS() { this.j[0] = this.gps(this.j, 4, new Pi(), new Fg()); } private int gps(int[] I, last int

(a) Outline the utilization of enum in Java programs and clarify any likenesses for and any distinctions from a Java class. [6 marks] The accompanying section of code shows an early endeavor to compose and test a Java program to reproduce the paper-scissors-stone game. In the technique principle() every one of the identifiers an and b is relegated one of the ite... (a) What is the distinction among MouseListener and MouseAdapter? [3 marks] (b) Via reasonable HTML, the incorporated form of the accompanying Java code is introduced to the appletviewer application: import java.applet.Applet; import java.awt.Graphics; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; public class MouseTest expands Applet { private String s = "Hi World"; public void init() { this.addMouseListener(new ML()); } public void paint(Graphics g) { g.drawReuseTest.this.s = "Mouse Pressed"; } } } Briefly make sense of what the code does and portray the underlying appearance of the applet window. [6 marks] (c) The software engineer moves the mouse pointer into the applet window, presses the mouse button and anticipates that another message should show up. For what reason doesn't it show up? Give three manners by which the normal outcome can be incited without leaving appletviewer. [6 marks] (d) The line MouseTest.this.paint(MouseTest.this.getGraphics()); is added to the technique mousePressed(). Portray the conduct now assuming the mouse button is squeezed when the pointer is in the applet. [3 marks] (e) What might have been a more proper change to the strategy mousePressed()? Make sense of.
