用java分裂字符串中的字符串

Question

如何将以下单词拆分为数组

That's the code

成

array
0 That
1 s
2 the
3 code

我试过这样的事

String str = "That's the code";

        String[] strs = str.split("\\'");
        for (String sstr : strs) {
            System.out.println(sstr);
        }

但输出是

That
s the code

Answer 1

要专门分割白色空间和撇号:

public class Split {
    public static void main(String[] args) {
        String [] tokens = "That's the code".split("[\\s']");
        for(String s:tokens){
            System.out.println(s);
        }
    }
}

或拆分任何非单词字符:

public class Split {
    public static void main(String[] args) {
        String [] tokens = "That's the code".split("[\\W]");
        for(String s:tokens){
            System.out.println(s);
        }
    }
}

如果您的字符串包含重音字母，我发现按单词分割的最佳解决方案是：

\n\n

String[] listeMots = phrase.split("\\\\P{L}+");\n

\n\n

例如，如果您的字符串是

\n\n

String phrase = "Salut mon homme, comment \xc3\xa7a va aujourd\'hui? Ce sera No\xc3\xabl puis P\xc3\xa2ques bient\xc3\xb4t.";\n

\n\n

然后您将得到以下单词（为了清晰起见，用引号括起来并用逗号分隔）：

\n\n

"Salut", "mon", "homme", "comment", "\xc3\xa7a", "va", "aujourd", "hui", "Ce", \n"sera", "No\xc3\xabl", "puis", "P\xc3\xa2ques", "bient\xc3\xb4t".\n

\n\n

希望这可以帮助！
