I am new here and relatively new to Java coding. I have been studying Java for a while and I started to follow some basic projects available. I got this project where we design a very simple bank application. I will paste the code below and ask my question now. In this code we define the UserName and UserId by typing them onto the code itself. If I wanted to ask the user for his name and ID, how could I do that. I tried using the Scanner function but I didn't know how to get the user answers, store it in a variable and then get the BankAccount method to use those inputs.
Thanks in advance for all the help.
