Answer 1

package javaapplication1;

public class JavaApplication1 {

    public static void main(String[] args) {

        int Arr[] = new int[]{130, 50, 99, 88, 35, 55, 10};

        BubbleSort(Arr);

        for (int i = 0; i < Arr.length; i++) {
            System.out.print(Arr[i] + " ");
        }
    }

    private static void BubbleSort(int[] Arr) 
    {
        int len = Arr.length;
        int tmp = 0;

        for (int i = 0; i < len; i++) {
            for (int j = 1; j < (len - i); j++) {
                if (Arr[j - 1] < Arr[j]) {
                    tmp = Arr[j - 1];
                    Arr[j - 1] = Arr[j];
                    Arr[j] = tmp;
                }
            }
        }
    }
}
