The code below removes any negative numbers from the supplied array that are outside the range and returns a new array.

static int[] remove_outside_range(int array[] , int lower_bound , int upper_bound){

ArrayList<Integer> al = new ArrayList<Integer>();

    for(int i=0; i < array.length; i++){

    if(array[i] > lower_bound){
    al.add(array[i]);
    }

    if(array[i] < upper_bound){
    al.add(array[i]);
    }

}

    int new_array[] = new int[al.size()];

    for(int i =0 ; i < al.size() ; i++){
    new_array[i] = al.get(i);
    }

    return new_array;
