我是这样解析的，一开始也懵了 //s为JSON字符串 s = s.substring(1, s.length() - 1); List<List<Integer>> list = new ArrayList<>(); char[] cs = s.toCharArray(); for (int i = 0; i < cs.length; ) { if (cs[i] == '[') { List<Integer> cur = new ArrayList<>(); while (cs[i] != ']') { if (cs[i] >= '0' &;&; cs[i] <= '9') { cur.add(Integer.parseInt(cs[i] + "")); } i++; } list.add(cur); i++; } else { i++; } }
