Java-拆分字符串？

我的绳子是

   String myString = "Hello   Boom,  Ho3w are || You ? Are  ^  you ," fr45ee   now ?";

我试着用下面的方法把绳子分开

“您好，Boom，Ho3w，are，You，are，You，fr45ee，now”-其中逗号表示字符串到字符串数组的分隔。我的代码是

  String[] temp = data.split("\\s+\\^,?\"'\\|+");

---

但这是行不通的。希望你们能帮上忙。谢谢。

我相信这应该行得通：

String myString = "Hello   Boom,  Ho3w are || You ? Are  ^  you ,\" fr45ee   now ?";
String[] arr = myString.split("\\W+");
//=> [Hello, Boom, Ho3w, are, You, Are, you, fr45ee, now]

---

您的示例无法编译，因为在

myString

变量中有一个未替换的双引号

但是，假设它是转义的

//                                                               | escaped " here
String myString = "Hello   Boom,  Ho3w are || You ? Are  ^  you ,\" fr45ee   now ?";
//                 | printing array
//                 |               | splitting "myString"...
//                 |               |               | on 1 or more non-word 
//                 |               |               | characters
System.out.println(Arrays.toString(myString.split("\\W+")));

输出

[Hello, Boom, Ho3w, are, You, Are, you, fr45ee, now]

如果您实际上只是试图拆分原始正则表达式中的字符，那么应该将

+

分解出来，并将所有内容放入一个字符类中

public class Split {
    public static void main(String[] args) {
        String myString = "Hello   Boom,  Ho3w are || You ? Are  ^  you ,\" fr45ee   now ?";
        String[] temp = myString.split("[\\s\\^,?\"'\\|]+");
        for (int i = 0; i < temp.length; i++)
            System.out.println(temp[i]); 
    }
}

myString

不是正确的字符串。您需要转义

“

字符。

Hello
Boom
Ho3w
are
You
Are
you
fr45ee
now
