java - 如果字符串后跟两个或多个空格/空格，如何拆分字符串? [英] How to split string if it is followed by two or more space/whitespace in java?

问题描述

在我的字符串中，我想根据两个或多个空格拆分字符串或标记字符串.

In my string, i want to split the string or tokenize string on the basis of two or more spaces.

例如

string = "I am  Chaitanya Gadam.      Split   this srting."

我希望输出为 -

str[0]= "I am"  
str[1]= "Chaitanya Gadam."  
str[2]= "Split"  
str[3]= "this string."  

推荐答案

string.split("\\s\\s+");

(或)

string.split("\\s{2,}");

 String string = "I am  Chaitanya Gadam.      Split   this srting.";

    String[] str = string.split("\\s{2,}");

    for(String s: str)
    {
        System.out.println(s+":"+s.length());
    }
    System.out.println(Arrays.toString(string.split("\\s\\s+")));

Output:
I am:4
Chaitanya Gadam.:16
Split:5
this srting.:12
[I am, Chaitanya Gadam., Split, this srting.]

用两个或多个空格作为分隔符分割字符串.在 Regex 中使用转义字符可以提高可读性，而不是使用空格字符.

Splits strings with two or more spaces as delimiter. Using Escape character in the Regex increases readability instead of using space character.
