如何按空格分割字符串

我在解析文本文件时需要帮助.文本文件包含类似

I need help while parsing a text file. The text file contains data like

This is     different type   of file.
Can not split  it    using ' '(white space)

我的问题是单词之间的空格不相似.有时只有一个空格，有时会给出多个空格.

My problem is spaces between words are not similar. Sometimes there is single space and sometimes multiple spaces are given.

我需要以这样一种方式分割字符串，使我只会得到单词，而不是空格.

I need to split the string in such a way that I will get only words, not spaces.

推荐答案

str.split("\\ s +")可以工作.正则表达式末尾的 + 将多个空格视为单个空格.它返回一个字符串数组( String [] )，没有任何" 结果.

str.split("\\s+") would work. The + at the end of the regular-expression, would treat multiple spaces the same as a single space. It returns an array of strings (String[]) without any " " results.
