regex pattern to find full stop, exclamation mark or question mark in Java
提问by Kazekage Gaara
I'm a newbie to regex. Here's the pattern that I could think of :
我是正则表达式的新手。这是我能想到的模式：
Pattern pattern = Pattern.compile("[.!?]");
Pattern pattern = Pattern.compile("[.!?]");
Because the documentationsays [abc] a, b, or c (simple class). But I'm wrong somehow. :-(
因为文档说[abc] a, b, or c (simple class). 但不知何故我错了。:-(

This works for me:
这对我有用：
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Main {
public static void main(String[] args) throws IOException {
Pattern pattern = Pattern.compile("[.!?]");
Matcher m = pattern.matcher("Hello?World!...");
while (m.find()) {
System.err.println(m.group());
}
}
}
So what is your issue more precisely?
那么您的问题更准确地说是什么？
