Try/catch block

public class UseTry
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

String getName()
{
try
{
return br.readLine();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
It gives an error "Method must return a result of type string" ..There is a solution if i explicitly throw Exception Like this

String getName() throws IOException
{
return br.readLine();
}

No error here..but the problem is that my program requires i should not explicitly throw the exception...

Can u all suggest sumthing to rectify this problem..
Thanks :)

you may declare and initialize varialbe xxx
and xxx = br.realine()
return xxx at the end of method

OR

return xxx in finally block

The error is you've not return anything from the complete path. Say in try block anything is not return due to any reason. So outside of the try-catch block you've not return anything too. But your method expecting to return something, and failed. Those things are validate in compile time.

Code:

---

    String getName() {

        try {
            return br.readLine();
        }
        catch (IOException e){
            e.printStackTrace();
        }
        return "";
    }

Ya, but I think the first way is much better, finally clause not complete all the way. New IDEs warn that as well, may be just a notification. Also more clear when you do in the end of the method your code readers.
