Random number generator continues to include 0

I'm trying to populuate an array with random numbers to be sorted and used in a binary search. All of my code seems to work fine except the generating part. The numbers need be between 1-32767 and I continue to get 0.

for(int i = 0; i < SIZE-1; i++){
   array[i] = (gen.nextInt(32767 - 1) + 1);
}

// Print out five entries
for(int i = 0; i < 5; i++){
   System.out.println(array[i]);
}

// Sort array
Arrays.sort(array);

// Print out first five sorted entries
for(int i = 0; i < 5; i++){
   System.out.println(array[i]);
}

After they're sorted and printed, the first entry is always 0. Perhaps this has to do with the array sorting, and I'm not realizing it. Any suggestions?

You're never setting the last element of the array -- use i < SIZE, not i < SIZE-1.
