kandi X-RAY | dolma Summary
This is the source code for our USENIX Security paper "DOLMA: Securing Speculation with the Principle of Transient Non-Observability". DOLMA is a defense against transient execution attacks, implemented in the gem5 simulator. When using code from this repository, please be sure to cite the paper. We recommend compiling and running this code on Ubuntu 20.04, as that's where we've tested our setup. However, you may be able to compile and run on Ubuntu 18.04. See this document for the differences in gem5 dependencies on Ubuntu 20.04 versus 18.04. To install the necessary dependencies on Ubuntu 20.04, run ./install_dependencies_ubuntu20.sh from the repo's top level directory (requires sudo). For Ubuntu 18.04, run , ./install_dependencies_ubuntu18.sh. To compile DOLMA, run python2 $(which scons) -j$(nproc) build/X86_MESI_Two_Level/gem5.opt from the repo's top level directory. The attacks we used to test DOLMA's security, along with usage instructions, can be found in attacks/. These can be used to verify DOLMA's availability, functionality, and reproducibility during artifact evaluation. See also artifact_evaluation/README.md.

QUESTION
I am making a quiz application in Java and am using JUnit to test my methods. Right now, my src folder has one main folder. The main folder further has two packages, model and UI. The model package contains one class called QuizQuestions and contains the modeling of data. The UI package has 2 classes, Quiz and Main. Quiz class provides print statements to the QuizQuestions class and the Main class has the Main method. Here is the code:
QuizQuestions class (model):
...ANSWER
Answered 2021-Oct-07 at 01:10There were a few issues with your code. I will summarize them here:
- Remove the qz = new Quiz() line in the constructor of the Quiz class, this led to a Stack Overflow as it kept running the constructor again and again.
- The main other issue in you code is instead of saving the score value for printing and other usage, it kept initializing new Quizes and running compareAnswers() in these new instances. You need to save the score value in the Quiz class, and use that stored value.
- Lastly, in the askQuestionsOneByOne() you are returning the user answers, but never use them. Instead, in compareAnswers() you are again initializing new Lists.
You can fix the Quiz class by adding a score field (first code example below). Then, in the main class, when you run compareAnswers(), which returns the score, save that to the current quiz (second code example below). Subsequently, when you need the score, for example in the displayScoreAndPerformance() call, retrieve it from the quiz object. Same for the printScore() in the Quiz object. For this to work, you need to add getter and setter for the Quiz object in the QuizQuestions.
Lastly, you need to parameterize the compareAnswers to accept the user's answers, and in the main method pass the result of the askQuestionsOneByOne() to the compareAnswers().
