Inheritance not working!

Hey everyone, I am basically trying to just use the super keyword to call my subclass:

Code :

---

public class SenderReceiver extends MultiEchoClient{
 
		public SenderReceiver(String host,int port){
			super(host,port);
		}
 
		public static void main(String args[]){
			if(args.length == 0){
			SenderReceiver senderReceiver = new SenderReceiver((String) "127.0.0.1",4433);
		}else{
			SenderReceiver senderReceiver = new SenderReceiver(args[0],4433);
		}
		//SenderReceiver.run();
		}
}

---

The super class has a constructor that passes String host,int port and so I am just trying to call that. I want to be able to have all the functionality in this new class so that if i mess up, then my superclass will be okay!

The compile error that i get is "unreported exception, must be caught or thrown". It is an IOException so I tried to encase the super(host,port); with a try catch block but it says that the super keyword must be declared first...

Thanks!

Declare the constructor to throw the exception - this will force any code that constructs a SenderReceiver to throw or catch the exception. See Lesson: Exceptions (The Java™ Tutorials > Essential Classes)

Thanks for the reply. I tried this:

Code :

---

public SenderReceiver(String host,int port)throws IOException{
			super(host,port);
		}

---

but get a "cannot retrieve symbol"

Post the full error. Did you import java.io.IOException?

ah, it looks like my objects were causing the issue. I shall have a look to see why that is. The throws IOException did the trick, thanks for your help copeg, much appreciated!
