Java : Sort integer array without using Arrays.sort()

Question

This is the instruction in one of the exercises in our Java class. Before anything else, I would like to say that I \'do my homework\' and I\'m not just being lazy asking someon

Answer 1

Simple way :

int a[]={6,2,5,1};
            System.out.println(Arrays.toString(a));
             int temp;
             for(int i=0;i a[j+1]){   // use < for Descending order
                         temp = a[j+1];
                         a[j+1] = a[j];
                         a[j]=temp;
                     }
                 }
             }
            System.out.println(Arrays.toString(a));

    Output:
    [6, 2, 5, 1]
    [1, 2, 5, 6]
