Question

I wanted to call the code in the main method, but it seems like it doesn’t really work.

public class RecursiveSelectionSort {

public static void sort(double [] list){


    sort(list, 0, list.length -1);
}
public static void sort(double [] list, int low, int high){
    if (low < high){
        int indexOfMin = low;
        double min = list[low];
        for(int i = low + 1; i <= high; i++){
            if(list[i]< min){
                min = list[i];
                indexOfMin = i;
            }
        }
        list[indexOfMin] = list[low];
        list[low] = min;

        sort(list, low + 1, high);
    }
}
public static void main(String [] args){
    double [] list = {3.0,4.0,1.0};//I tried but it doesn't work
    System.out.print(sort(list));//it doesn't go to sort(list);
}
}

I was wondering if I can call it. It seems easy, but really confusing.

sort is a void method, you can’t print its result. Try sorting first and then printing the list separately.
