package com.test.tool;
import java.util.ArrayList;
import java.util.HashSet;
import java.util.regex.*;

public class MatchTest {
	public static void main(String[] args)
	{

	            String regex = "[0-9]{5,12}";
		   String input = "QQ120282458,QQ120282458 QQ125826";
	            Pattern p = Pattern.compile(regex);
		        Matcher m = p.matcher(input);
		        ArrayList al=new ArrayList();

		        while (m.find()) {

		             
		            al.add(m.group(0));
		        }
		        System.out.println("去除重复值前");
		        for (int i=0;i

输出结果为:

去除重复值前
120282458
120282458
125826
去除重复值后
125826
120282458

 

 

改进版:弄成一个bean:
