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]

You have a file Ghost.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) {         Ghost t = new Ghost();         // each of the lines below is run independently        System.out.println(t.age);    // compiles and runs        System.out.println(t.getPower()); // compile error        System.out.println(t.power); // compiles and runs     } }  —— in a separate file in a different package/directory ———  public class Ghost {        1   int age;       2   int power;       3   int getPower() {        return power;     }     /** no-argument constructor implemented **/ }    1  :[vis1]   2  :[vis2]   3  :[vis3]

You have a file State.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) {         State t = new State();         // each of the lines below is run independently        System.out.println(t.getAveragePopulation()); // compile error System.out.println(t.averagePopulation); // compiles and run System.out.println(t.numCounties);    // compiles and runs     } }  —— in a separate file in a different package/directory ———  public class State {        1   int numCounties;       2   double averagePopulation;       3   double getAveragePopulation() {        return averagePopulation;     }     /** no-argument constructor implemented **/ }    1  :[vis1]   2  :[vis2]   3  :[vis3]

Given the following code, what is the value of b?   String x = “BROCCOLI”; String y = x; x.toUpperCase(); boolean b = (y.equals(x)); 

Given the if/else block, choose the corresponding ternary expression.   int a = 8; int b = 15; int result;if (b > a) { result = a + b; } else { result = b / a; } 

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 (doggo) { case ‘r’: System.out.println(“rocko”); case ‘c’: System.out.println(“chispa”); break; default: System.out.println(“nope”); case ‘m’: System.out.println(“moccita”); }     if (1._______________) {  2._______________________ 3._______________________ } else if (4._______________) { System.out.println(“chispa”); } else if (5.________________) {  System.out.println(“moccita”); } else { 6._______________________ 7._______________________     }
