java - java中数组排序的算法

Question

我想对一个int数组进行从小到大的排序。我已经创建了下一个算法，但问题是新数组没有从 if 语句接收到正确的值。我将把我的代码放在下面。

 public static void main(String[] args) {
    int[] arr = {33,44,22,11,22,11};
    int[] arrSort = new int[6];
    int temp=0;
        for (int i = 0; i < arrSort.length - 1; i++) {
            if (arr[i] > arr[i + 1]) {
                temp = arr[i + 1];
                arr[i + 1] = arr[i];
                arrSort[i] = temp;
            }

            else {
                arrSort[i] = arr[i];
            }
        }
    System.out.println(Arrays.toString(arrSort));
}

如果我运行代码，我会得到下一个值:[33, 22, 11, 22, 11, 0];

我只是想弄清楚算法的哪一部分被认为是错误的。预先感谢您。

You need to apply 2 loops.
1st loop is to access 1st arr element.
2nd loop is to access next(1st + 1)th element.
After comparing 1st element with other swap it accordingly. 

public static void main(String []args)
     {
        int[] arr = {33,44,22,11,22,11};
        int len=arr.length;
        int temp=0,i,j;

        for (i = 0; i < len; i++) 
        {
            for (j = i+1; j < len; j++)
            {
                if (arr[i] > arr[j]) 
                {
                    temp = arr[i];
                    arr[i] = arr[j];
                    arr[j] = temp;
                }
            }
        }
        for(i=0; i<arr.length; i++)
        {
            System.out.println(arr[i]);
        }
     }
