一个数组数组,请组合成一个最大的数字字符串

public static String largestNumber(int[] nums) {

        String[] array = new String[nums.length];
        for (int i = 0; i < nums.length; i++) {
            array[i] = String.valueOf(nums[i]);
        }

        String temp;
        for (int i = 0; i < array.length; i++) {
            for (int j = i + 1; j < array.length; j++) {
                if ((array[i] + array[j]).compareTo(array[j] + array[i]) < 0) {
                    temp = array[i];
                    array[i] = array[j];
                    array[j] =temp;
                }
            }
        }

        if (array[0].equals("0")) {
            return "0";
        } else {
            return Arrays.toString(nums).replace("[","").replace("]","").replace(", ","");
        }
    }

    public static void main(String[] args) {
        int[] nums = {5,56,67,110};
        System.out.println(largestNumber(nums));
    }

 最后打印结果是:55667110
