正则表达式（十四）——找出某一个网页内部的所有的邮箱

package com.wy.regular;

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class RegularTest {

    public static void main(String[] args) {
        BufferedReader br = null;
        try {
            br=  new BufferedReader(new FileReader("D:\xxx\正则表达式\2018919.html"));
            String line = "";
            while ((line = br.readLine()) != null) {
                parse(line);
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {

    }

    private static void parse(String line) {
        Pattern pattern = Pattern.compile("[\w[.-]]+@[\w[.-]]+\.[\w]+");
        Matcher matcher = pattern.matcher(line);
        while (matcher.find()) {
            pri(matcher.group());    
        }
    }

    public static void pri(Object object){
        System.out.println(object);
    }
}

结果：
