java - 按单词拆分java中的字符串

Question

如何将下面的单词拆分成一个数组

这就是代码

进入

array
0 That
1 s
2 the
3 code

我试过这样的东西

String str = "That's the code";

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

但是输出是

That
s the code

Answer 1

专门针对空格和撇号进行拆分:

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);
        }
    }
}
