Withdraw, Deposit & check your balance in the NEW Java Banking App

public class bankAccount

First, we create a bankAccount class with 4 instance variables we'll be using thorughout the program:

1. int balance;
2. int previousBalance;
3. String customerName;
4. String customerID;

underneath that, we create our bankAccount constructor with 2 params.

deposit, withdraw & getPreviousTransaction methods

Next we create 3 methods that give our application functionaility yo do things.

• deposit(), withdraw() and getPreviousTransaction() are comprised of math equations that fulfill each of their expected functions.
• Later down the line the int amount variable will equal scan.nextInt() - the user's next int input.

showMenu()

The first block of code executed that acts as our aesthetics in terminal

• initializes char option;

showMenu() - cont.

This methods also coninueously runs a do/while loop with 5 different switch options

Main

Stylistically - I like to keep my Main clean as possible.

• Here, we create a new bankAccount instance and execute showMenu()

Finished product

Takeaways

• Orgainization and style matter - easier to read and follow (by other and myself). Separation of concerns.
• It's easier to break down a program by looking at its smaller blocks of code.
• initialize -> constructor -> invoke new object
