【Java】java | 字符串转二维数组

一、作业要求

1、将数组字符串转成二维数组

2、字符串

"[[1,2,3],[3,4,5]]"

3、依赖hutool

二、代码

public static void main(String[] args) {
        String str = "[[1,2,3],[3,4,5]]";
        JSONArray array = JSONUtil.parseArray(str);
        int[][] vals = new int[2][3];
        for (int i = 0; i < array.size(); i++) {
            JSONArray inneis = array.getJSONArray(i);
            for (int j = 0; j < inneis.size(); j++) {
                vals[i][j] = (int)inneis.get(j);
            }
        }
        for (int i = 0; i < vals.length; i++) {
            int[] inneiVals = vals[i];
            for (int j = 0; j < inneiVals.length; j++) {
                System.out.println(inneiVals[j]);
            }
        }
    }
