This video explains a challenge to create a bank account program in Scala. The challenge includes creating a bank account class and a singleton object that is used to keep track of the next account number to be assigned.
- [Instructor] Are you ready for the last challenge…in this series?…In this challenge, we're going to start…by creating a new project in your Scala IDE…then we're going to add a Scala app.…What I'd like you to do is inside that app,…I want you to add a class to create a bank account.…The bank account will include the client name,…the starting balance and the account type,…checking or savings.…Then, use a singleton for the account number,…start it at 5000.…In the main program,…create several instances of bank accounts…and print out your results.…
It might be helpful to go back to the video on classes…where I created a payroll app.…The bank account app is going to be very similar to that.…I'm estimating this challenge will take…about 15 minutes so go ahead and give it a try and have fun.…
