主要的类方法

package demo.phone;

import java.io.FileInputStream;

import java.io.IOException;
import java.util.Properties;
import java.util.regex.Pattern;

public class Phone {
	private String unicom;
	private String chinamobile;
	private String reg_templete;
	private String runicom;
	private String rchinamobile;
	public Phone() {
		//读取配置文件
		Properties prop = new Properties();
		try {
			prop.load(new FileInputStream("D://workspace//gsj//phone//src//demo//phone//config.properties"));
			//联通的号段
			unicom=prop.getProperty("unicom");
			//移动的号段
			chinamobile=prop.getProperty("chinamobile");
			//表达式模板
			reg_templete=prop.getProperty("reg_templete");
			//联通的表达式
			runicom=reg_templete.replaceAll("_phone_",unicom);
			//移动的表达式
			rchinamobile=reg_templete.replaceAll("_phone_",chinamobile);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	public int validate(String phone){
		if(validateUnicom(phone))
			return 1;//联通的号码
		if(validateChinamobile(phone))
			return 2;//移动的号码
		return 0;//小灵通号码
	}
	//判断是否是联通的号码
	private boolean validateUnicom(String phone){
		return Pattern.compile(runicom).matcher(phone).matches();
	}
	//判断是否是移动的号码
	private boolean validateChinamobile(String phone){
		return Pattern.compile(rchinamobile).matcher(phone).matches();
	}
}

用于测试的方法

package demo.phone;

public class Main {

	public static void main(String[] args) {
		//如果是1表示联通，2移动，3小灵通
		Say("013578481235");
		Say("13678481235");
		Say("13378481235");
		Say("13178481235");
		Say("015978481235");
		Say("99690814");
		Say("89892015");
	}
	public static void Say(String phone){
		Phone p = new Phone();
		System.out.println(phone+"  "+p.validate(phone));
	}
