Which, when inserted at line 13, allows another class to get the value of the salary variable, but NOT change the value of the salary variable?

#72. Given:

 1. public abstract class Wow { 
 2. private int wow; 
 3. public Wow(int wow) { 
 4. this.wow = wow; 
 5. } 
 6. public void wow() { } 
 7. private void wowza() { } 
 8. }

Which is true about the class Wow?

#73. Given:

 1. interface A { } 
 2. interface B { void b(); } 
 3. interface C { public void c(); } 
 4. abstract class D implements A,B,C { } 
 5. class E extends D { 
 6. void b() { } 
 7. public void c() { } 
 8. }

Which is true?

#74. Given:

 1. interface Flyer { 
 2. void takeOff(); 
 3. boolean land();

 3. public X(Y y) { this.y = y; } 
 4. } 
 5. class Y { 
 6. private X x; 
 7. public Y() { } 
 8. public Y(X x) { this.x = x; } 
 9. }

The instance variable y is intended to represent the composition relationship "X is composed of Y."
Which code correctly maintains this meaning?

#77. Given:

 5. class Foo { 
 6. public int fooInt = 6; 
 7. } 
 8. 
 9. public class Bar { 
 10. static int myInt = 7; 
 11. public static void main(String [] args) { 
 12. // insert code here 
 13. System.out.println("myInt = " + myInt); 
 14. } 
 15. }

Which, inserted at line 12, creates the output myInt = 42?
