java - 如何按其他分隔符拆分字符串

Question

有一个字符串

String str = "ggg;ggg;nnn;nnn;aaa;aaa;xxx;xxx;";

如何将它拆分成这样的字符串 “呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜 “恩恩；恩恩；” “aaa；aaa；” “xxx；xxx；” ????????

Answer 1

使用 Regex

    String input = "ggg;ggg;nnn;nnn;aaa;aaa;xxx;xxx;";
    Pattern p = Pattern.compile("([a-z]{3});\\1;");
    Matcher m = p.matcher(input);
    while (m.find())
        // m.group(0) is the result
        System.out.println(m.group(0));

会输出

ggg;ggg;

nnn;nnn;

aaa;aaa;

xxx;xxx;
