problem with dereferencing

public static boolean binarySearch (int[] data, int min,
int max, int value)
{
boolean result;
int midpoint = (min + max) / 2; // determine the midpoint

if (data[midpoint].compareTo(value) == 0)
result = true;
else if (data[midpoint].compareTo(value) > 0)
{
if (min <= midpoint - 1)
result = binarySearch(data, min, midpoint - 1, value);
else
result = false;
}
else if (midpoint + 1 <= max)
result = binarySearch(data, midpoint + 1, max, value);
else
result = false;

return result;
}//method binarySearch


this code gives me the following error:

"int cannot be dereferenced". Can anyone suggest a possible fix?

Thanks !

I believe you would have to get the value that you wish to test out of the array first. ie...

Code:

---

int[] ints = {1, 2, 3};
int x = ints[1];

---

You're trying to call compareTo, which is a method of Integer, on an plain int. Not good.

Use Integer's static compareTo, and call it only once (and use [code][/code] tags!!!)

Better yet, directly compare the ints.

Code:

---

public static boolean binarySearch (int[] data, int min,
int max, int value) {
  boolean result = false;
  int midpoint = (min + max) / 2; // determine the midpoint
  if (data[midpoint] == value) {
    result = true;
  } else if (data[midpoint] > value) {
    if (min <= midpoint - 1) {
      result = binarySearch(data, min, midpoint - 1, value);
    } else {
      result = false;
    }
  } else if (midpoint + 1 <= max) {
    result = binarySearch(data, midpoint + 1, max, value);
  }

  return result;
}//method binarySearch
