Java错误“重写的方法不会引发java.io.IOException”？

Question

This may be a very newbie question, but Is there a way to start a thread that creates sockets? Because I can't do the following:

public void run() throws IOException{

  Socket sock2 = new Socket("localhost", 9898);


}

and I get this error:

run() in CapitalizeClient cannot implement run() in java.lang.Runnable overridden method does not throw java.io.IOException

Or should I just create the socket code in the main? I'd like to periodically create sockets to use as a heartbeat. thanks

You cannot put throws IOException in the run method because the Runnable interface does not say that the run method throws any checked exceptions.

Either handle the IOException by catching it, or move the code to another location.
