Java - Selection Sort Algorithm

Question

I have some questions about selection sort.I\'m a little bit confused.

 int [] arr = {5,4,3,2,1}; // This is my array
    int min = 0;

    for(int i = 0;i&l         


        

Answer 1

Assume a lowest element, which requires scanning the all elements and then swap it to the first position.

private static void selectionSortMethod(int[] arr) {

        for (int i = 0; i < arr.length - 1; i++) {  //no of iterations for array length
            for (int j = i + 1; j < arr.length; j++) {  //starting from next index to lowest element(assuming 1st index as lowest)
                if (arr[i] > arr[j]){
                    int temp = arr[i];
                    arr[i] = arr[j];
                    arr[j] = temp;
                }
            }

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