一个测ip和端口是否联通的工具类

public class TestIp {
public static void main(String[] args) {
Socket connect = new Socket();

try {
connect.connect(new InetSocketAddress("192.168.0.59", 8071),100);

boolean res = connect.isConnected();
System.out.println("" + res);
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
connect.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
