Consider the two overloaded bubble sort methods in the BubbleSorter class. Which statement about their stability is correct?

public class BubbleSorter {
    public void sort(int[] arr) {
        for(int i = 0; i < arr.length; i++) {
            for(int j = 0; j < arr.length - 1; j++) {
                if(arr[j] > arr[j+1]) {
                    int temp = arr[j];
                    arr[j] = arr[j+1];
                    arr[j+1] = temp;
                }
            }
        }
    }
    
    public void sort(double[] arr) {
        for(int i = 0; i < arr.length; i++) {
            for(int j = 0; j < arr.length - 1; j++) {
                if(arr[j] > arr[j+1]) {
                    double temp = arr[j];
                    arr[j] = arr[j+1];
                    arr[j+1] = temp;
                }
            }
        }
    }
}
