  these picture shows that the algorithm of the selection sort the code is below in (java) ****************************************************************** public class selectionSort{ public void sort(int[] A){ for(int i=0; i<A.length; i++){ int minIndex =i; for(int j=i; j<A.length; j++){ if(A[minIndex] > A[j]){ minIndex = j; } }    // Swapping the minIndex Element and first element  int temp = A[i]; A[i] = A[ minIndex ]; A[ minIndex ] = temp; } } } ****************************************************************** public class selectionSortDemo{ public static void main(String args[]){ int A[] = {7,3,2,5,1}; selectionSort S = new selectionSort(); S.sort(A); for(int i=0; i<A.length; i++){ System.out.print(A[i]+" "); } } } ******************************************************************************

Bubble Sort is a simple sorting algorithm. It repeatedly comparing each of the adjacent pair and swap them like the above animation.
