#31. Given:

 8. int index = 1; 
 9. int [] foo = new int [3]; 
 10.int bar = foo [index]; 
 11.int baz = bar + index;

What is the result?

#32. Given:

 1. public class foo { 
 2. public static void main (String[]args) { 
 3. String s; 
 4. system.out.printIn (“s=” + s); 
 5. } 
 6.}

What is the result?

#33. Which will declare a method that forces a subclass to implement it?

#34. You want subclasses in any package to have access to members of a superclass. Which is the most restrictive access modifier that will accomplish this objective?

#35. Given:

 1. abstract class abstrctIt { 
 2. abstract float getFloat (); 
 3. ) 
 4. public class AbstractTest extends AbstractIt { 
 5. private float f1= 1.0f; 
 6. private float getFloat () {return f1;} 
 7. }

What is the result?

#36. Exhibit:

 1. public class test( 
 2. public int aMethod()[ 
 3. static int i=0; 
 4. i++; 
 5. return I; 
 6. ) 
 7. public static void main (String args[]){ 
 8. test test = new test(); 
 9. test.aMethod(); 
 10.int j = test.aMethod(); 
 11.System.out.printIn(j); 
 12.] 
 13.}

What is the result?

#37. Given:

 1. class super { 
 2. public float getNum() {return 3.0f;} 
 3. ) 
 4. 
 5. public class Sub extends Super { 
 6. 
 7.)

Which method,placed at line 6,will cause a compiler error?

#38. Which declaration prevents creating a subclass of an outer class?

#39. Given:

 1.byte [] arry1,array2 []; 
 2.byte array3 [][]; 
 3.byte [][] array4;

If each array has been initialized, which statement will cause a compiler error?

#40. Exhibit:

 1. class super ( 
 2. public int I = 0; 
 3. 
 4. public super (string text) ( 
 5. I = 1 
 6. ) 
 7. ) 
 8. 
 9. public class sub extends super ( 
 10. public sub (string text) ( 
 11. i= 2 
 12. ) 
 13. 
 14. public static void main (straing args[]) ( 
 15. sub sub = new sub (“Hello”); 
 16. system.out. PrintIn(sub.i); 
 17. ) 
 18. )

What is the result?
