Section 6: Arrays

Question: Is the reference a "pointer"?

• No, Java restricts programmers from interfacing with pointers. Pointers exist behind the scenes and Java uses them to manage references, but you don't have to worry about them.

Section 7: Objects

Question: Can I call setters from the constructor to update fields?

• Yes

  
  

Question: When can something be null?

• When it's non-primitive (i.e class type).

Section 8: Exception Handling

Question: Why are checked exceptions called compile-time exceptions?

• Java forces you to catch checked exceptions during compile time.

Question: Why are unchecked exceptions called runtime exceptions?

• Java ignores them during compile time. They can crash the app during runtime.

Sections 9: Unit Testing

Question: Unit testing is not working in Visual Studio Code.

• Inside Visual Studio Code, open settings.json (CMD/Ctrl + shift + P)

• Add a comma after the last entry in your JSON file

• After the comma, add the snippet from the video.

Windows users, the path you put in V.S code should have forward slashes ( / )!!

Workbooks and Challenges

Question: The Tic Tac Toe challenge is really hard. How should I proceed?

• I understand it may be overwhelming, but difficult tasks reflect what you can expect in the real world. Most courses will just show you how to code something, but I want you to practice problem-solving with code. If you find the task to be too hard, my recommendation is to start by looking at the solution, run it, and slowly delete different parts of the code until you can isolate what each thing does. Then, once you have an idea of how it works, start fresh and try to incrementally solve it yourself. Most importantly, take your time!
