#51. Given:

 1. class Super { 
 2. public int getLenght() { return 4; } 
 3. } 
 4. 
 5. public class Sub extends Super { 
 6. public long getLenght() { return 5; } 
 7. 
 8. public static void main(String[] args) { 
 9. Super sooper = new Super(); 
 10. Sub sub = new Sub(); 
 11. System.out.println( 
 12. sooper.getLenght() + “,” + sub.getLenght() ); 
 13. } 
 14. }

What is the output?

#52. Given:

 1. public class Test { 
 2. public static void main(String[] args) { 
 3. int x = 0; 
 4. assert (x > 0): “assertion failed”; 
 5. System.out.println(“finished”); 
 6. } 
 7. }

What is the result?

#53. You want to limit access to a method of a public class to members of the same class. Which access accomplishes this objective?

#54. Given:

 11. switch(x) { 
 12. default: 
 13. System.out.println(“Hello”); 
 14. }

Which two are acceptable types for x? (Choose two)

#55. Given:

 1. public class X { 
 2. public static void main(String [] args) { 
 3. try { 
 4. badMethod(); 
 5. System.out.print(“A”); 
 6. } 
 7. catch (RuntimeException ex) { 
 8. System.out.print(“B”); 
 9. } 
 10. catch (Exception ex1) { 
 11. System.out.print(“C”); 
 12. } 
 13. finally { 
 14. System.out.print(“D”); 
 15. } 
 16. System.out.print(“E”); 
 17. } 
 18. public static void badMethod() { 
 19. throw new RuntimeException(); 
 20. } 
 21. }

What is the result?

#56. Given:

 1. public class Test { 
 2. public static void main(String[] args) { 
 3. int x = 0; 
 4. assert (x > 0) ? “assertion failed” : “assertion passed”; 
 5. System.out.println(“Finished”); 
 6. } 
 7. }

What is the result?

#57. Given:

 1. public class ReturnIt { 
 2. return Type methodA(byte x, double y) { 
 3. return (long)x / y * 2; 
 4. } 
 5. }

What is the narrowest valid returnType for methodA in line2?

#58. Given:

 1. public class OuterClass { 
 2. private double d1 = 1.0; 
 3. // insert code here 
 4. }

Which two are valid if inserted at line 3? (Choose two)

#59. Given:

 1. public class Foo { 
 2. public void main( String[] args ) { 
 3. System.out.println( “Hello” + args[0] ); 
 4. } 
 5. }

What is the result if this code is executed with the command line? java Foo world

#60. Given:

 11. public void foo( boolean a, boolean b ){ 
 12. if( a ) { 
 13. System.out.println( “A” ); 
 14. } else if ( a && b ) { 
 15. System.out.println( “A&&B” ); 
 16. } else { 
 17. if ( !b ) { 
 18. System.out.println( “notB” ); 
 19. } else { 
 20. System.out.println( “ELSE” ); 
 21. } 
 22. } 
 23. }

What is correct?
