I'm developing a custom Exception class, in which I have the following constructors:
public class UserException extends Exception
{
string message;
public UserException() {
super();
}
public UserException(String message, Throwable cause)
{
super(message, cause);
this.cause = cause;
this.message = message;
}
}
And I create a new custom exception like this:
private Camera.PreviewCallback SetPreviewCallBack() throws UserException {
.......
// Something went wrong
throw new UserException("Something failed.", new Throwable(String.valueOf(UserExceptionType.CaptureFailed)));
}
But when I insert my throw new UserException(...)
it tells me to surround it with try/catch
!! That's not the idea, isn't it? I want to throw custom exceptions when I need them to be thrown, without surronding my new Exceptions
with more try/catch
clauses.
So, what I'm doing wrong? What I'm misunderstanding?
In addition to Eran's answer, you could also make your custom Exception extend RuntimeException
, which does not need to be caught.
