    I suggested that you create a NEW array of the desired size.
    Then copy the elements from the old array to the new array. The Arrays class has a method to do that.

    ArrayList is a java class. See the API doc for how to create one and what methods it has.
    If you don't understand my answer, don't ignore it, ask a question.

    I have set my original 2 arrays to 10, so now if I make a third array to copy my 2nd array to, then there will be some slots that will be filled with 0's and those will get copied over. I guess I should of done your array list way in the beginning but I dont think I am allowed use arraylist for this.

    If you have an array with 10 slots with the first 6 elements containing data
    and create a new array with 6 slots
    and copy the first 6 slots from the first array to the second array, (See the Arrays class for a method)

    there will NOT be any empty slots with 0s in the new array.

    Im aware of that but am I just trying to make it fool proof, as in what if there happens to be 7 or n + 1 matches then it has to be an array of 7 elements, and since my array is one of the first things I would declare I would not be able to change it.

    Create the new array WHEN you know how large it needs to be. The new code I've described would replace this statement:
    valueFound.length = count;

    After the copy was made, valueFound could be assigned the new array.
