Name __________________________________

Assume the following:

   int[] a = {25, -3, 6, 0, -3, 6};
   int[] b = new int[100];
   int[] c = null;

1. _____________ Value of a.length ?
2. _____________ Value of b.length ?
3. _____________ Value of b[50] ? Write "illegal" if this is illegal.
4. _____________ Value of c[50] ? Write "illegal" if this is illegal.
5. _____________ Value of n after:

       int n = 0;
       for (int i=0; i<a.length; i++) {
           if (a[i] < 0) {
               n++;
           }
       }

6. _____________ Value of n after

       int n = 0;
       c = a;
       int n = c[1];

7. _____________ Value of n after

       int n = 0;
       c = a;
       for (int i=0; i<a.length; i++) {
           c[i] = a[i]+1;
       }
       n = a[2];

8. _____________ Value of n after

       int n = 0;
       for (int i=0; i<a.length-1; i++) {
          for (int j=i+1; j<a.length; j++) {
              if (a[i] == a[j]) {
                  n++;
              }
          }
       }
