This is what I came up with. Whether it's really better or not I think
depends on your requirements. Lightly tested.
public static int test3( InputStream ins )
throws MyEndOfInputException
{
Scanner scanner = new Scanner( ins );
while( scanner.hasNext() ) {
if( scanner.hasNextInt() )
return scanner.nextInt();
else
scanner.next();
}
throw new MyEndOfInputException();
}
}
class MyUtilsException extends Exception
{
}
class MyEndOfInputException extends MyUtilsException
{
}
