The fоllоwing clаss describes аn Accоunt. public clаss Account { private int accountId, accountBalance; public Account(int id, int balance) { accountId=id; accountBalance=balance; } public boolean transferMoney(Account otherAccount, int transferAmount) { /*postcondition: * if otherAccount has at least transferAmount * the transfer to the current Account is made and * true is returned * otherwise * the transfer is not made and * false is returned */ //missing code } public String toString() { return accountId+" has balance $"+accountBalance; } //other methods not shown } An Account object has an accountId and an accountBalance. The method transferMoney takes as parameters: the Account object otherAccount. transferAmount, the amount of money to transfer from otherAccount to the current Account. When this method is completed, it will do the following: if otherAccount has at least transferAmount the transfer to the current Account is made and true is returned otherwise the transfer is not made and false is returned For example, if the following code segment appears in a client program: Account a1=new Account(13567,5000); Account a2=new Account(24567,2000); System.out.println("Starting balances:"); System.out.println(a1); System.out.println(a2); System.out.println(); System.out.println("1. Try to transfer $1000 from 24567 to 13567"); if (a1.transferMoney(a2,1000)==true) System.out.println("Successful transfer"); else System.out.println("Unsuccessful transfer"); System.out.println(a1); System.out.println(a2); System.out.println(); System.out.println("2. Try to transfer $1100 from 24567 to 13567"); if (a1.transferMoney(a2,1100)==true) System.out.println("Successful transfer"); else System.out.println("Unsuccessful transfer"); System.out.println(a1); System.out.println(a2); The output should be: Starting balances: 13567 has balance $5000 24567 has balance $2000 1. Try to transfer $1000 from 24567 to 13567 Successful transfer 13567 has balance $6000 24567 has balance $1000 2. Try to transfer $1100 from 24567 to 13567 Unsuccessful transfer 13567 has balance $6000 24567 has balance $1000 Which of the following code segments should replace //missing code so that transferMoney works as intended? A if (this.transferAmount>otherAccount.accountBalance) return false; this.accountBalance+=this.transferAmount; otherAccount.accountBalance-=this.transferAmount; return true; B if (transferAmount>this.accountBalance) return false; this.accountBalance+=transferAmount; otherAccount.accountBalance-=transferAmount; return true; C if (transferAmount>otherAccount.accountBalance) return false; this.accountBalance+=transferAmount; otherAccount.accountBalance-=transferAmount; return true; D if (transferAmount>otherAccount.accountBalance) return false; this.accountBalance+=transferAmount; otherAccount.accountBalance-=transferAmount;
Cоnsider the fоllоwing incomplete clаss. public clаss Plаyer { private String playerName; private int playerScore; private static int highScoreAllPlayers = -1; //High score for all players private static String highScorePlayerName = ""; //Player who has high score public Player(String name, int score) { playerName = name; playerScore = score; } public String getPlayerName() { return playerName; } public int getPlayerScore() { return playerScore; } // Insert methods here } The following code is written in another class to test the Player methods and make sure they work without compilation errors. Player sally = new Player("Sally", 100); sally.checkHighScore(); System.out.println(Player.getPlayerNameAndScore()); Player joe = new Player("Joe", 80); joe.checkHighScore(); System.out.println(Player.getPlayerNameAndScore()); Which of the following methods could be inserted in the Player class so that the above tests run without compilation errors? A public void checkHighScore() { if (playerScore > highScoreAllPlayers) { highScoreAllPlayers = playerScore; highScorePlayerName = playerName; } } public static String getPlayerNameAndScore() { return getPlayerName() + ": " + getPlayerScore(); } B public void checkHighScore() { if (playerScore > highScoreAllPlayers) { highScoreAllPlayers = playerScore; highScorePlayerName = playerName; } } public static String getPlayerNameAndScore() { return highScorePlayerName + ": " + highScoreAllPlayers; } C public static void checkHighScore() { if (playerScore > highScoreAllPlayers) { highScoreAllPlayers = playerScore; highScorePlayerName = playerName; } } public static String getPlayerNameAndScore() { return getPlayerName() + ": " + getPlayerScore(); } D public static void checkHighScore() { if (playerScore > highScoreAllPlayers) { highScoreAllPlayers = playerScore; highScorePlayerName = playerName; } } public static String getPlayerNameAndScore() { return highScorePlayerName + ": " + highScoreAllPlayers; }
