D sounds interesting, but does it really work for detecting unused variables?

C doesn't even apply to Java, right?

Surprised that people still overlook PMD for Java!

Glenn 1 year ago

I disagree, A won't help with Java quality checks.

Shonda 1 year ago

B is the way to go! PMD is great for catching those issues.

I don't recall all the build tools, but I think Grunt and Gulp are more for JavaScript. Could it really be B?

Brittni 1 year ago

I feel like we practiced a similar question, and PMD was definitely mentioned as a solution for Java applications.

I'm not entirely sure, but I remember something about using build tasks to check for unused variables. Was it Maven or something else?

I think PMD is the tool we learned about for detecting code quality issues in Java. It might be option B?

Hmm, I'm a bit unsure about this one. The options seem pretty similar, and I'm not entirely sure what the key differences are between them. I'll need to re-read the question and think it through step-by-step.

Hmm, this is a tricky one. I'd want to test on a device that represents the majority of iOS users, so I'm thinking iPhone 7 might be the best option.

Hmm, I'm a bit unsure about this one. I know location data can be used for things like language preferences and device detection, but I'm not totally sure which of these options is the best fit.

I think the first step is to figure out how much Longview covers above that $2,600,000 threshold, but it feels tricky to get to the final number!
