Day 7 of learning Java

[u/BigCommunication5136]

I relearned the Abstraction and Encapsulation OOP concepts on Day 6 and refactored the Mortgage Calculator project.

Open to suggestions on how to improve the project, OOP-wise

I have few questions :-

1. Why have u used byte data type for years ?

2. Why have u done Console.readNumber() ?

3. Why have u taken final keyword for the instance variables ?

[u/BigCommunication5136 → u/souroexe]

1. If you watch closely, the allowed number of years is up to 30 and byte is more than enough.

2. I encapsulated the logic for reading a value from a user, and I didn’t want to initialize a new object whenever I want to input a value that’s why I used the static keyword

3. TBH it was a suggestion from intelliJIDE
