Java IP + 端口 读取校验

import static org.junit.Assert.*;

@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
    @Test
    public void useAppContext() {

        String b = "192.168.30.98:65536";
//校验地址中是否存在 “ip:端口号”  （例如rtsp://admin:[email protected]:554/media/video1 ）
        Pattern p = Pattern.compile("(\\d+\\.\\d+\\.\\d+\\.\\d+)\\:(\\d+)");
        Matcher m = p.matcher(b);
//将符合规则的提取出来
String ip=null;
String port= null;
        while(m.find()) {
            ip =  m.group(1);
            port = m.group(2);
            System.out.println("ip:"+m.group(1));
            System.out.println("isboolIp:"+isboolIp(ip));

        }
    }

    /** * 判断是否为合法IP * @return the ip */

        String ip = "([1-9]|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])(\\.(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])){3}";
        Pattern pattern = Pattern.compile(ip);
        Matcher matcher = pattern.matcher(ipAddress);
        return matcher.matches();
    }

    public static boolean isboolPort(String port) {
        //端口号验证 1 ~ 65535
        String regex = "^([1-9]|[1-9]\\d{1,3}|[1-6][0-5][0-5][0-3][0-5])$";
        boolean flag = Pattern.matches(regex, port);
        return  flag;

    }
