如何使用替换、子字符串、拆分等执行字符串操作

Question

我有这样的字符串数据

string1 = ["car","house","boat"]["one","two","three","four"]["tiger","cat"]

我希望输出是这样的:

first : car,house,boat
second : one,two,three,four
third : tiger,cat

我应该如何对该字符串进行操作？

这是我目前的尝试：

result6 = string1.substring(1);
String[] parts = result6.split("\[");
String part1 = parts[0];
String part2 = parts[1];
String part3 = parts[2];
result3 = part1.replaceAll("[^a-zA-Z0-9,]", "");
result4 = part2.replaceAll("[^a-zA-Z0-9,]", "");
result5 = part3.replaceAll("[^a-zA-Z0-9,]", "");
result1 = "first : " + part1 + "\n" + "second : " + part2 + "\n" + "third : \n" + part3;

但这让我得到了错误的输出。

您在 result1 赋值部分添加了 part1、part2、part3 而不是 result3、4、5。而且我建议你根据 ][ 进行拆分，如果你只根据 [ 进行拆分，你会在 parts[0].

中得到一个空字符串

String string1 = "[\"car\",\"house\",\"boat\"][\"one\",\"two\",\"three\",\"four\"][\"tiger\",\"cat\"]";
String parts[] = string1.split("\]\[");
String part1 = parts[0];
String part2 = parts[1];
String part3 = parts[2];
String result3 = part1.replaceAll("[^a-zA-Z0-9,]", "");
String result4 = part2.replaceAll("[^a-zA-Z0-9,]", "");
String result5 = part3.replaceAll("[^a-zA-Z0-9,]", "");
String result1 = "first : " + result3 + "\n" + "second : " + result4 + "\n" + "third : " + result5;
System.out.println(result1);

输出：

first : car,house,boat
second : one,two,three,four
third : tiger,cat
