       public class selectionSort{
     
          public static void main(String[]args){
     
             double[] array = {1, 9, 4.5, 6.6, 5.7,};
            	selectionSort(array);
     
          }
     
          public static void selectionSort(double[]array){
     
             for (int i =0; i<array.length-1; i++){
     
                double min = array[i];
     
                int minIndex = i;
     
                for (int j = i+1;  i<array.length; i++){
                   if ( min> array[i])
     
                      array[i]= min;
                }
     
                if ( minIndex!=i){
                   array[minIndex]= array[i];
                   array[i]= min;
     
                }
             }
          }
       }

    ----jGRASP exec: java selectionSort

    Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 5
    at selectionSort.selectionSort(selectionSort.java:25)
    at selectionSort.main(selectionSort.java:6)

    ----jGRASP wedge2: exit code for process is 1.

    Default Re: selectionsort

    Valid indicies for an array are 0 to length - 1. For an array that has a length of 5 the last index is 4 which makes 5 out of bounds.
