从两个字符之间获取字符串 [英] Get string from between two characters

问题描述

我需要从两个字符之间获取字符串。我有这个

I need to get string from between two characters. I have this

S= "10:21:35 |Manipulation       |Mémoire centrale   |MAJ Registre mémoire"

并且它必须在变量中返回4个字符串：

and it have to return 4 strings each in a variable:

a=10:21:35
b=Manipulation
c=Mémoire centrale
d=MAJ Registre mémoire

推荐答案

String＃split 。由于它接受正则表达式字符串，并且 | 是正则表达式中的特殊字符，因此您需要将其转义（使用反斜杠）。由于 \ 是Java字符串文字中的特殊字符，因此您还需要转义 it ，人们有时会感到困惑。所以给定：

There's String#split. Since it accepts a regular expression string, and | is a special character in regular expressions, you'll need to escape it (with a backslash). And since \ is a special character in Java string literals, you'll need to escape it, too, which people sometimes find confusing. So given:

String S = "10:21:35 |Manipulation |Mémoire centrale |MAJ Registre mémoire";

然后

String[] parts = S.split("\\|");
int index;
for (index = 0; index < parts.length; ++index) {
    System.out.println(parts[index]);
}

将输出

10:21:35 
Manipulation 
Mémoire centrale 
MAJ Registre mémoire

（ With 前三位的尾随空格; trim 如有必要。）

(With the trailing spaces on the first three bits; trim those if necessary.)
