A Command Loop

TestBankAccount.java

public static void main(String args[]) { BankAccount account; // the bank account we are testing int amountAsInt; // amount parameter as int double amountAsDouble; // amount parameter as double String command; // command line char cmdletter; // first character of the command account = new BankAccount(); // Process commands from the input do { command = RitIo.getString("Your command: "); cmdletter = command.charAt(0); switch (cmdletter) { // ... } } while (cmdletter != 'x'); }

This little test program allows to access all methods of the BankAccount class by using one-letter commands.
