Question

In Java if I want to get the elements from an array that fall in a specific range then what would be the most efficient way to do that?

For e.g.

array

A = [25,32,54,23,76,34];

And I want to get the

element between 45 and 55.

That is the element:

54

So what will be the most efficient way to get it?

Answer 1

I am not sure if it would be the most efficient, but I would do something like this.

    int[] rangeTracker = new int[100];
int rangeTrackIndex = 0;
For (int j = 0; j < A.getLength(); j++) {

     if ((A[j] >= 45) && (A[j] <= 55)) {
          rangeTracker[rangeTrackIndex] = A[j];
          rangeTrackIndex++;
}
}
For (int j=0; j < rangeTracker.getLength(); j++) {
     System.out.println(rangeTracker[j]);
}

Some of my syntax could be off and this could be the wrong way to do it, but I have only been working with Java for about 2 months. Furthermore I have only been working with programming for about 4 months. I hope this helps.
