I need to sort the array in ascending order only for the positive value. For the negative value the index position will remain the same as it is.

If the array is : int[] inputArray = {-1, 150, 190, 170, -1, -1, 160, 180}.

The output should be like this - int[] outputArray = {-1, 150, 160, 170, -1, -1, 180, 190}.

But in my case the output is this - int[] outputArray = {-1, 150, 170, 190, -1, -1, 160, 180}.

Here is my code below :

public static void main(String[] args) {
    int[] inputArray = {-1, 150, 190, 170, -1, -1, 160, 180};
    int[] outputArray = sortByHeight(inputArray);

    for (int item : outputArray) {
        System.out.print(item + ", ");
    }
}

public static int[] sortByHeight(int[] inputArray) {
    for (int i=0; i<inputArray.length; i++) {
        for (int j = 0; j<inputArray.length - 1; j++) {
            int temp = inputArray[j];
            if (temp >= 0) {
                if (inputArray[j] > inputArray[j+1] && inputArray[j+1] >= 0) {
                    inputArray[j] = inputArray[j+1];
                    inputArray[j+1] = temp;
                }
            }
        }
    }
    return inputArray;
}

public static void sortByHeight(int[] inputArray) {
    List list = new ArrayList();
    for (int i = 0; i < inputArray.length; i++) {
        if (inputArray[i] > 0)
            list.add(inputArray[i]);
    }
    Collections.sort(list);
    int j=0;
    for (int i = 0; i < inputArray.length; i++) {
        if (inputArray[i] > 0){
            inputArray[i] = Integer.parseInt(list.get(j).toString());
        j++;}
    }

    for (int i = 0; i < inputArray.length; i++) {
        System.out.println(inputArray[i]);
    }
