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=3D"";
    boolean DidItWork=3DGetString(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.
