Question

For this Project you need to add methods after every case so that after every function like withdraw, deposit, and check balance it only runs when called.

```java package bankteller; import java.util.Scanner; public class BankTeller { public static void main(String[] args) { int balance = 1000, withdraw, deposit; Scanner s = new Scanner(System.in); while (4 != 0) { System.out.println("Menu"); System.out.println("Choose 1 for Deposit"); System.out.println("Choose 2 for Withdraw"); System.out.println("Choose 3 for Check Balance"); System.out.println("Choose 4 for Exit"); System.out.println("Choose 0 to continue"); int n = s.nextInt(); switch (n) { case 1: System.out.println("Enter amount for deposit"); deposit = s.nextInt(); balance = balance + deposit; System.out.println("Your money has been deposited"); break; // Additional cases would follow for withdrawing, checking balance, exiting, etc. } } } } ``` **Explanation:** The code defines a simple command-line banking application within the `BankTeller` class. It manages basic operations such as depositing money. The `main` method initializes a balance and uses a `Scanner` to collect user input. For demonstration purposes, only the deposit option is fully implemented. Here's a breakdown of how the application works: - **Variables:** - `balance`: an integer initialized to 1000. - `withdraw`, `deposit`: placeholders for withdraw and deposit amounts. - **Menu Options:** - `1` for making a deposit. - Additional numbers (2, 3, 4) suggest further functionality (withdraw, check balance, exit) but are not implemented in the visible code section. - **Functionality Explained:** - The `while (4 != 0)` loop keeps running the menu until a mechanism for breaking is implemented. - Inside the loop, the program prints the menu options. - The `switch` statement is used to handle the user's choice from the menu. If the user selects `1`, they are prompted to enter a deposit amount, which is added to the `balance`. - The result of the deposit operation is confirmed with a message. Note that code structuring, break conditions, or other features such as error handling for invalid inputs are not fully described in the shown implementation.

The image shows a snippet of Java code handling a simple banking operation. Below is the transcription of the code, with explanations appropriate for an educational website: ```java case 2: System.out.println("Enter amount for withdraw"); withdraw = s.nextInt(); if (balance >= withdraw) { balance = balance - withdraw; System.out.println("Collect amount withdrawn"); } else { System.out.println("Insufficient Balance"); } case 3: System.out.println("Balance : " + balance); case 4: System.out.println("Balance : " + balance); System.out.println("Thank you have a good day"); case 5: System.out.println("Do you want to continue(0?)"); s.nextInt(); ``` **Explanation:** - **Case 2:** This section is responsible for handling withdrawal transactions. The program prompts the user to enter an amount to withdraw. If the balance is sufficient (i.e., greater than or equal to the withdrawal amount), the balance is reduced by the withdrawal amount, and the user is instructed to collect the amount. If the balance is insufficient, the program informs the user of this status. - **Case 3 and Case 4:** These cases print the current balance. In case 4, an additional message, "Thank you have a good day," is displayed. - **Case 5:** This case asks the user if they wish to continue, expecting an integer input from the user. This code is part of a larger switch-case construct often found in simple banking systems for managing user transactions. It provides basic functionalities such as withdrawing funds and checking account balance.
