java - 如何在java中转义],[序列？

Question

在用java编写代码时，我需要用“],[”分割字符串。下面是我的代码。

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
            int i=0;
            String line;
            line = reader.readLine();
            String[] split = line.split("],[");
            StringBuilder sb = new StringBuilder();
            sb.append(split[0]);
            String joined = sb.toString();
            System.out.println(joined);

        } 

请在这里帮忙。

你必须转义[。喜欢:

line.split("\\],\\[");

您的代码将是:

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
        int i=0;
        String line;
        line = reader.readLine();
        String[] split = line.split("\\],\\[");
        StringBuilder sb = new StringBuilder();
        sb.append(split[0]);
        String joined = sb.toString();
        System.out.println(joined);

    }
