A fun little Java Gotchas quiz and supporting Github repo showing some gotchas and how to fix them
A previous blog post described the Java Gotcha "Bitwise vs Boolean Operator".
We added a variant of this, and some other Java Gotchas into a fun little Quiz called "Challenge The Sensei".
If you've read the blog post above then you'll be in a good place to ace at least one of the questions.
But your friends might not, so if you find the quiz fun, you can share it with them and see if they score as well as you.
Since we don't want to just quiz you. We want to try and use this to help educate and codify the knowledge. So we have created a Github repo that has runnable code examples for the problem, and the solution.
This is a Sensei enabled repo.
When you clone the repo and load it into IntelliJ, assuming you have the Secure Code Warrior Sensei IntelliJ Plugin installed, then it will automatically see that you have a .sensei folder, and load the Sensei recipes.
When browsing the code in the IDE you should see IntelliJ prompt you that the error exists in the code, and this should make it easier to see the gotcha in the code:
Sensei recipes have been added for:
We are adding more recipes and more explanatory text to cover the rest of the code in the future... but don't let that stop you from having a look at the code and spotting the error yourself.
And remember to try the quiz and "Challenge the Sensei"
