Question

1. Let Account be the bank account class discussed in Chapter 3. What balance will be stored in acct1, acct2, and acct3 after the following statements have been executed?;Account acct1 = new Account(200.00);Account acct3 = new Account(200.00);Account acct2= acct3;acct1.withdraw(50.00);acct2.deposit(100.00);acct3.deposit(50.00);2. Suppose that f1 and f2 are Fraction objects, where Fraction is the class described in Chapter 3. Write a statement that adds f1 and f2 and stores the result in a variable named f3. (The method that adds fractions is named add.) You may assume that f3 has already been declared as a Fraction variable.;3. Show the output of the following program.;public class Problem47;public static void main(String[] args);String msg1 = "CSc 226J is available next quarter;String msg2 = "Get a grip!;String msg3 = "Now, let's eat!;String sub1 = msg1.substring(7, 15);String sub2 = msg2.substring(6, 8);String sub3 = msg3.substring(11, msg3.length());System.out.println(sub1.substring(0, 1) +;sub1.substring(5, sub1.length()) +;sub1.substring(1, 5) +;sub2 + sub3);Output = Java is great!;4.What will be printed when the following statements are executed?;Account acct1 = new Account(1000.00);Account acct2 = new Account(1000.00);if (acct1 == acct2);System.out.println("Equal");else;System.out.println("Not equal");5. Following is a part of the source codes for NFLTeam3 and NFLGameDay3 classes. To make sure one can run the following NFLGameDay3 and print the meaningful win/loss number of the teams on the screen, please write necessary methods to finish the class of NFLTeam3 (hints: at least 3 more methods are needed).;public class NFLTeam3;privateint win;privateint loss;private String name;public void winAgame();win++;public void winAgame(NFLTeam3teamB);win++;teamB.lossAgame();public void lossAgame();loss++;//end of NFLTeam3 class definition;public class NFLGameDay3;public static void main (String [] args);NFLTeam3 falcons = new NFLTeam3("falcons");NFLTeam3 steelers = new NFLTeam3("steelers");falcons.lossAgame(steelers);System.out.println (falcons);System.out.println (steelers);6. For each of the following code segments, how many times will ``Hello World'' be printed out when the code segment is executed? Briefly explain each answer. Be careful, some of these are tricky!;a) int i;for (i = 0, i <= 10, i++);System.out.println("Hello World");b) int i;for (i = 1, i < 10, i++);if (i % 3 == 0);System.out.println("Hello World");c) int i;for (i = 1, i <= 25, i++);System.out.println("Hello World");7. Of the following if statements, which one correctly executes three instructions if the condition is true?;A) if (x < 0);a = b * 2;y = x;z = a - y;B);if (x < 0);a = b * 2;y = x;z = a - y;C) if { (x < 0);a = b * 2;y = x;z = a - y;D) if (x < 0);a = b * 2;y = x;z = a - y;E) B, C and D are all correct, but not A
