Java字符串到数组的拆分

Question

我有一个字符串，例如："My brother, John, is a handsome man."

我想把它拆分成一个数组，这样输出就是：

"My" , "brother", "," , "John", "," , "is", "a", "handsome", "man", "."

有人能帮我吗？我需要在Java上做到这一点。

Answer 1

replaceAll()和split()的组合应该可以做到这一点。

public static void main(String[] args) {
    String s ="My brother, John, is a handsome man.";
    s = s.replaceAll("(\\w+)([^\\s\\w]+)", "$1 $2");  // replace "word"+"punctuation" with "word" + <space> + "punctuation" 
    String[] arr = s.split("\\s+"); // split based on one or more spaces.
    for (String str : arr)
        System.out.println(str);
}

O/P：

My
brother
,
John
,
is
a
handsome
man
.

Answer 2

如果只考虑,和.，那么一种方法是使用replace()和split()

String x =  "My brother, John, is a handsome man.";
String[] s = x.replace(",", " ,").replace(".", " .").split("\\s+"); 

for (String str : s)
    System.out.print("\"" + str + "\"" + " ");

输出：

"My" "brother" "," "John" "," "is" "a" "handsome" "man" "." 

Answer 3

尝尝这个。

    String string = "My brother, John, is a handsome man.";
    for (String s : string.split("\\s+|(?=[.,])"))
        System.out.println(s);

结果是

My
brother
,
John
,
is
a
handsome
man
.
