Exhibit:
1 . public class X implements Runnable(
2 . private int x;
3 . private int y;
4 .
5 . public static void main(String[]args)
6 . X that = new X();
7 .(new Thread(that)).start();
8 .(new Thread(that)).start();
9 .)
1 0.
1 1. public void run()(
1 2. for (;;)(
1 3. x++;
1 4. y++;
1 5. System.out.printIn("x=" + x + ", y = " + y);
1 6.)
1 7.)
1 8.)
What is the result?

• A. Errors at lines 7 and 8 cause compilation to fail.
• B. The program prints pairs of values for x and y that are always the same on the same line (forexample, "x=1, y=1". In addition, each value appears twice (for example, "x=1, y=1" followed by"x=1, y=1").
• C. The program prints pairs of values for x and y that might not always be the same on the same line(for example, "x=2, y=1").
• D. The program prints pairs of values for x and y that are always the same on the same line (for example, "x=1, y=1". In addition, each value appears only for once (for example, "x=1, y=1" followed by "x=2, y=2").

Given:
1 . package foo;
2 .
3 . public class Outer (
4 .public static class Inner (
5 .)
6 . )
Which statement is true?

• A. An instance of the inner class can only be constructed from within the outer class.
• B. From within the package bar, an instance of the inner class can be constructed with
  "new inner()"
• C. An instance of the Inner class can be constructed with "new Outer.Inner ()"
• D. An instance of the inner class cannot be constructed outside of package foo.

Which two statements are true? (Choose Two)

• A. An anonymous inner class constructor can take arguments in some situation.
• B. Even if a class Super does not implement any interfaces, it is still possible to define an anonymous inner class that is an immediate subclass of Super that implements a single interface.
• C. Event if a class Super does not implement any interfaces, it is still possible to define an anonymous inner class that is an immediate subclass of Super that implements multiple interfaces.
• D. An anonymous inner class can be declared inside of a method
• E. An anonymous inner class that is a direct subclass that is a direct subclass of Object can implementmultiple interfaces.

CORRECT TEXT
Exhibit:
1 . public class X {
2 . public static void main (String[]args) {
3 . string s = new string ("Hello");
4 . modify(s);
5 . System.out.printIn(s);
6 .}
7 .
8 . public static void modify (String s){
9 . s += "world!";
1 0.}
1 1. }
What is the result?
E.The program runs and prints "Hello"
F.An error causes compilation to fail.
G.The program runs and prints "Hello world!"
H.The program runs but aborts with an exception.

Which statement about static inner classes is true?

• A. Instance members of a static inner class can be referenced using the class name of the static innerclass.
• B. A static inner class cannot be a static member of the outer class.
• C. An anonymous class can be declared as static.
• D. A static inner class does not require an instance of the enclosing class.
