QUESTION
My professor asked me to make a program about cashier using Java. The program is supposed to be inputting the codename of the product and how much you buy it.
Before printing the value, the program will ask you "do you want to count another [Y/N]". If the user inputting Y then the user will asked to input another value. And then the program will sum every inputs as a total and print it.
I'm almost successful in making the program, but I don't know how to make loop for inputting another value without override the first value. And then I can sum total value each input. As I know using for loops makes you to set the value of maximum loops, before starting loops.
And this is what I'm trying to do

QUESTION
I would appreciate your guidance in the following problem. I need to bulk extract only the articles titles from a series of publications. The idea is that I receive the files in PDF, I extract only the first page (done), bulk convert to TXT (done), and I am stuck in the last phase.
The structure of the TXTs is as follows:
--- JOURNAL of MEDICINE and LIFE
JML | REVIEW
The role of novel poly (ADP-ribose) inhibitors in the treatment of locally advanced and metastatic Her-2/neu negative breast cancer with inherited germline BRCA1/2 mutations. A review of the literature
Authors list, etc, etc ---
In need only the title (in bold), from each file. I can do the iteration, that is not a problem.
With the code below I tried to identify paragraph 1:

Answered 2021-Mar-18 at 20:14You might read the whole file using .read() and use a pattern with a capture group to match from JML to Authors.

QUESTION
I am a bit new to java and so while programming i have noticed that i have to give JML annotations to my subroutines. As i was working with object-oriented programming i have noticed the use of interfaces and that i have to declare the method there with JML specification, the questions is, when after i have my interface done and i now implement the methods in the classes who implement the interface, as i declare the class once again should i also specify the JML specification above the class once again or this can be omitted as it is located in the interface?
...ANSWER
Answered 2021-Jan-13 at 21:02The JML verification tool should be aware of this situation, but you need consult the documentation of the used verification tools. For example, for KeY (an interactive theorem prover for Java/JML) its behavior is well described in the second KeY book, which is similar to Leavens:
In JML, specification inheritance means that instance methods have to obey the specifications of all methods they override. This, together with the inheritance of invariants and history constraints, forces subtypes to be behavioral subtypes [Dhara-Leavens96] [Leavens-Naumann06] [Leavens06b].
So you do not need to repeat the JML contract, and your verification tool should verify the overridden methods against the contract in the super type.

Answered 2021-Jan-02 at 07:40Your issue is with overwriting the original template in the first iteration and in other iterations in your loop, that template no longer is valid for your work. Try something like this,

I'm given a task where I have to remove every warning produced by JML.
If I call a method inside the constructor my requires and ensures are not verified anymore, despite adding the same constraint for the called function.
I am asked to use only requires, ensures, invariant and loop_invariant.
Here is the code:
ANSWER
Answered 2020-Dec-24 at 13:11The prover cannot establish whether or not the class variables change as the function has visibility over n and elements. Thus it should need an annotation like
QUESTION
I have the following piece of code:
...ANSWER
Answered 2020-Dec-21 at 00:34Use loop invariants, since they provide loop preconditions (assumptions) that are used to establish assertions. You need to specify all of the invariants related to every variable that is being modified. Also, you need an extra condition requires src != dest, because the prover can run into an aliasing problem, and avoid using a lot of index arithmetic in the assertions, see https://github.com/OpenJML/OpenJML/issues/716 (special thanks to David Cok for this clarification, one of the maintainers of OpenJML).
Here is a version of your method with proper contract and loop invariants that is verifiable:

I have this query:

Answered 2020-Oct-12 at 07:12An EXISTS subquery is there to qualify which rows you want to select. It does not add rows or columns to the result set.
Reduce the list of columns in the SELECT clause of your sub query to any single one of the columns, or even a literal - such as SELECT 1 - and you will get your duplicates:
