Array remove duplicate elements

Question

I have an unsorted array, what is the best method to remove all the duplicates of an element if present?

e.g:

a[1,5,2,6,8,9,1,1,10,3,2,4,1,3,11,3]
         


        

Answer 1

    indexOutput = 1;
    outputArray[0] = arrayInt[0];
    int j;
    for (int i = 1; i < arrayInt.length; i++) {            
        j = 0;
        while ((outputArray[j] != arrayInt[i]) && j < indexOutput) {
            j++;
        }
        if(j == indexOutput){
           outputArray[indexOutput] = arrayInt[i];
           indexOutput++;
        }         
    }
