Java在新数组中对索引进行排序

import java.util.Arrays;

public class IndexSort {
    public static void main(String[] args) {
        int[] array = {5, 2, 7, 1, 9};
        int[] sortedIndexes = new int[array.length];

        for (int i = 0; i < array.length; i++) {
            sortedIndexes[i] = i;
        }

        Arrays.sort(sortedIndexes);

        int[] sortedArray = new int[array.length];

        for (int i = 0; i < array.length; i++) {
            sortedArray[i] = array[sortedIndexes[i]];
        }

        System.out.println("Original Array: " + Arrays.toString(array));
        System.out.println("Sorted Array: " + Arrays.toString(sortedArray));
    }
}

Original Array: [5, 2, 7, 1, 9]
Sorted Array: [1, 2, 5, 7, 9]
