Part 1: Design and implement an application that simulates a simple slot machine, which displays three images randomly chosen in three slot positions: a. Slot Machine Driver

//Driver for SlotsMachinePanel package programming.assignment.pkg2; import javax.swing.JFrame; public class SlotMachine { //-------------------------------- // Creates the main program frame. //-------------------------------- public static void main (String[] args) { JFrame frame = new JFrame ("Slot Machine"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(new SlotMachinePanel()); frame.pack(); frame.setVisible(true); } }

b. Slot Machine Panel:

//----------------------------------- // Slot Machine Panel //----------------------------------- package programming.assignment.pkg2; import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.Random; public class SlotMachinePanel extends JPanel { private JPanel buttonPanel, newSlotsPanel, primary; private JButton spin, cashout; private JLabel spinlabel, cashoutlabel, slotsPanelLabel1, slotsPanelLabel2; private JLabel imageLabel; private ImageIcon icon; private int spinResult = 0; private int currentTokens = 5; //--------------------------------------------------------------------- //Constructor: Sets up the SlotMachine GUI. //--------------------------------------------------------------------- public SlotMachinePanel () { //Creation of primary (Background Panel) primary = new JPanel ();

After clicking “Spin” in order to play again, the ‘current tokens’ reverted back to 5 tokens.

Part 2: Design and implement a driver class called CountFlips whose main method flips a coin 100 times and counts how many times each side comes up. Print the results. a. Driver:

public class CountFlips { //----------------------------------------------------------------- // Creates a Coin object, flips it, and prints the results. //----------------------------------------------------------------- public static void main (String[] args) { final int numFlips = 100; int heads = 0; int tails = 0; Coin myCoin = new Coin(); for (int count = 1; count <=numFlips; count++) { myCoin.flip(); if (myCoin.isHeads()) heads++; else tails++; } System.out.println ("The number flips: " + numFlips); System.out.println ("The number of heads: "+ heads); System.out.println ("The number of tails: "+ tails); }

b. Coin Class (unmodified): public class Coin { private final int HEADS = 0; private final int TAILS = 1; private int face; //----------------------------------------------------------------- // Sets up the coin by flipping it initially. //----------------------------------------------------------------- public Coin () { flip(); } //----------------------------------------------------------------- // Flips the coin by randomly choosing a face value. //----------------------------------------------------------------- public void flip () { face = (int) (Math.random() * 2); } //----------------------------------------------------------------- // Returns true if the current face of the coin is heads. //----------------------------------------------------------------- public boolean isHeads () { return (face == HEADS); } //----------------------------------------------------------------- // Returns the current face of the coin as a string. //----------------------------------------------------------------- public String toString() { String faceName; if (face == HEADS) faceName = "Heads"; else faceName = "Tails"; return faceName; } }

Extra Credit: Design and implement an application that plays the Hi-Lo guessing game. a. Programming of HiLow game: //--------------------------------// // Hi-Low guessing game. // Extra Credit for Oct. 31 //--------------------------------// import java.util.Random; import javax.swing.JOptionPane; public class HiLow { public static void main (String[] args) { String numStr, correct; int lost; do { int guess; int answer; int guessNum = 0; //--System picks random number--// Random generator = new Random(); answer = generator.nextInt(100) + 1; numStr = JOptionPane.showInputDialog ("Enter an integer between 1 and 100: \n" + "(Warning! You get 5 guesses!)"); guess = Integer.parseInt(numStr); while (guessNum<4) { if (guess < answer) { numStr = JOptionPane.showInputDialog ("Your guess (" + guess + ") is low \n" + "Enter another integer: "); guess = Integer.parseInt(numStr); guessNum++; } else if (guess > answer) { numStr = JOptionPane.showInputDialog ("Your guess (" + guess + ") is high \n" + "Enter another integer: "); guess = Integer.parseInt(numStr); guessNum++; } else {
