比较线不起作用，为什么？我该如何解决它？

Question

public static void main(String[] args) {
    int[] my_Numbers= {1789, 2035, 1899, 1456, 2013, 
            1458, 2458, 1254, 1472, 2365, 
            1456, 2165, 1457, 2456};
    for(int i=0; i < my_Numbers.length;){
        if (Integer.compare(my_Numbers[i],my_Numbers[(i+1)])==1) {
            int x = my_Numbers[i];
            my_Numbers[i] = my_Numbers[i+1];
            my_Numbers[i+1] = x;
            i=0;
        }else {i++;}
    }
    String  result= my_Numbers.toString();
    System.out.println(result);
}

Answer 1

试试这个：

public static void main(String[] args) {
    int[] my_Numbers= {1789, 2035, 1899, 1456, 2013,
            1458, 2458, 1254, 1472, 2365,
            1456, 2165, 1457, 2456};
    for(int i=0; i < my_Numbers.length-1;){
        if (Integer.compare(my_Numbers[i],my_Numbers[(i+1)])==1) {
            int x = my_Numbers[i];
            my_Numbers[i] = my_Numbers[i+1];
            my_Numbers[i+1] = x;
            i=0;
        }else {i++;}
    }
    String  result= Arrays.toString(my_Numbers);
    System.out.println(result);
}

首先在执行之前添加 if 条件 (i+1(，因为它会在 i 是最后一个元素时给你 arrayindexoutof bound 异常。
