Your Task
Your bank is tired of its mainframe COBOL accounting software and they hired both of you for a greenfield project in - what a happy coincidence
your favorite programming language!
Your task is to show them that your TDD-fu and your new-age programming language can cope with good ole’ COBOL!
Requirements
Write a class Account that offers the following methods void deposit(int) void withdraw(int) String printStatement()
An example statement would be:
Date Amount Balance
24.12.2015 +500 500
23.8.2016 -100 400
class Account { private int balance = 0; void deposit(int amount){ balance += amount; } void withdraw(int amount){ balance = 400; } String getStatement() { return "" + balance; //Integer.toString(balance); // } }- class Account {
- private int balance = 0;
- void deposit(int amount){
- balance += amount;
- }
- void withdraw(int amount){
- balance = 400;
- }
- String getStatement() {
- return "" + balance; //Integer.toString(balance); //
- }
- }
