Unreported excep. IOException must be caught or declared to be thrown

[garishnikov]

I'm getting this message when trying to compile. This is what the code in question looks like:

import java.io.*;

public class User

{

String userName;
String userHand;
int handNumber;
String choice;

public User() throws IOException

{

BufferedReader theInput = new BufferedReader (new InputStreamReader(System.in));

System.out.println();
System.out.println("Welcome to RPS. What is your name?"
userName = theInput.readLine();
}
}

Any ideas?? Thanks

Hi garishnikov,

I cut and pasted your code and it compiled fine for me.

Hi garishnikov:

I copy pasted it too and it worked. This is my Java version:

java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

I think that your jvm version could be the reason.

Hope it helps.

I will guess that somewhere in your project you have another .java file with a main() method, and in that method you have something like:

User myUser = new User();

So the User constructor is defined to throw an exception and the calling code is not handling the exception. The calling fuction being main(). So either change the signature of main to throw the exception or put the User construction code into a try/catch block

public int main(...) throws Exception
{
  User myUser = new User();
}
