Java: Cannot initialize InetAddress

Question

I can't seem to be able to initialize InetAddress object for some reason, I looked at the documentation and it is exactly as how I use it.

 InetAddress firstMachineAddress = InetAddress.getByName("129.26.70.95");
 InetAddress secondMachineAddress = InetAddress.getByName("129.26.70.108");

And Eclipse says:

Default constructor cannot handle exception type UnknownHostException thrown by implicit super constructor. Must define an explicit constructor

What the heck is wrong?

Answer 1

Your code seems to be in a class's constructor which is extended by another class, like so:

import java.net.*;

class SuperclassWithUnknownHostException {
    public SuperclassWithUnknownHostException() throws UnknownHostException {
        InetAddress firstMachineAddress = InetAddress.getByName("129.26.70.95");
        InetAddress secondMachineAddress = InetAddress.getByName("129.26.70.108");
    }
}

class SubclassCannotHandleException extends SuperclassWithUnknownHostException {

}

You need to add a default constructor to the subclass which throws the exception:

class SubclassCannotHandleException extends SuperclassWithUnknownHostException {
    public SubclassCannotHandleException() throws UnknownHostException {

    }
}
