You have a file Bank.java and you have a driver class named Driver.java. Fill in the correct visibility modifiers so that the comments in the main method are upheld.  public class Driver {     public static void main(String[] args) {         Bank t = new Bank();        // each of the lines below is run independently        System.out.println(t.totalMoney); // compiles and run        System.out.println(t.getTotalMoney()); // compiles and runs System.out.println(t.id);    // compile error     } }  —— in a separate file in a different package/directory ———  public class Bank {        1   int id;       2   double totalMoney;       3   double getTotalMoney() {        return totalMoney;     }     /** no-argument constructor implemented **/ }    1  :[vis1]   2  :[vis2]   3  :[vis3]

Convert the following switch statement to an if-else block so the output is the same for all cases. Assume the switch variable is already declared and initialized. Note that some lines may need to be blank, if that is the case and there are multiple lines in the block, the blank line MUST BE THE LAST LINE in the block.  For example (follow this format):   if (a == 10) { sum += 10; //LEAVE BLANK }   Instead of (do NOT do this):   if (a == 10) { //LEAVE BLANK sum += 10; }  Some lines may be used once, never, or multiple times.  switch (food) { case 1: System.out.println(“arepas – delicious”); case 2: System.out.println(“falafel – mouthwatering”); break; default: System.out.println(“nay”); case 3: System.out.println(“ceviche – scrumptious”); }     if (1._______________) {  2._______________________  3._______________________ } else if (4._______________) {  System.out.println(“falafel – mouthwatering”); } else if (5.________________) {  System.out.println(“ceviche – scrumptious”); } else {  6._______________________  7._______________________     }

Given the if/else block, choose the corresponding ternary expression.   int a = 9; int b = 3; int result;if (a == b) { result = a / b; } else { result = a – b; } 

Write 2-3 lines of code to:  Declare a String variable and save your favorite color in it. Print the value of the variable to the console with a newline character after it.  Make sure to select the ‘Preformatted’ style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD.

Given the following code, what is the value of b?   String str1 = “Tomatoes”; String str2 = str1; str2.replace(‘m’,’?’); boolean b = (str1.equals(str2));

For the given code below, which lines are valid (will compile and run)? Assume each line is run independently.   public class Foo {     private static int number;     private int jar;     public static double fuzz() {        return 0.0;     }     public int flop() {        return 0;     }     public static void main(String[] args) {         Foo obj = new Foo();        1 obj.fuzz();        2 obj.flop();        3 Foo.fuzz();        4 Foo.flop();                                    5 System.out.println(obj.number);        6 System.out.println(obj.jar);        7 System.out.println(Foo.number);          8 System.out.println(Foo.jar);      } }    1  : [1]   2  : [2]   3  : [3]   4  : [4]   5  : [5]   6  : [6]   7  : [7]   8  : [8]
