一、代码

package algorithm;

public class SelectionSort {

    public static void selectionSort(int[] arr) {
        if (null == arr || arr.length <= 0) {
            return;
        }

        for (int i = 0; i < arr.length - 1; i++) {
            int minIndex = i;
            for (int j = i + 1; j < arr.length; j++) {
                if (arr[minIndex] > arr[j]) {
                    minIndex = j;
                }
            }
            int temp = arr[i];
            arr[i] = arr[minIndex];
            arr[minIndex] = temp;
        }

        print(arr);
    }

    private static void print(int[] arr) {
        for (int e : arr) {
            System.out.print(e + " ");
        }
    }

    public static void main(String[] args) {
        int[] arr = {13, 7, 5, 8, 64, 2, 4, 62, 0, 1};
        selectionSort(arr);
    }

}
