I'm not sure I understand the problem here.
I think what you want to be able to write (but Java won't let you) is
this:
String ReturnString="";
boolean DidItWork=GetString(ReturnString);
if (!DidItWork) {
handleErrorOrThrowException();
} else {
doSomethingWithString();
}
Patricia and others have suggested that the idiomatic way in Java to
do it is to use an exception like this:
try {
doSomethingWith(getString());
} catch (SomeErrorOccuredException e) {
handleErrorOrThrowException();
}
That looks perfectly reasonable to me.
