To build a banking transaction system using Java, you will need to follow some steps:
Define the classes: Start by defining the classes that you will need for your banking transaction system. You will likely need a Bank class to represent the bank, an Account class to represent the customer's account, and a Transaction class to represent each transaction.
Implement the classes: Once you have defined the classes, implement them in Java. For example, the Bank class might contain a list of Account objects, and the Account class might contain information about the account balance and the account holder.
Add functionality: Once the basic classes are implemented, you can add functionality to your banking transaction system. For example, you might add methods to allow customers to deposit money, withdraw money, or view their account balance. You might also add methods to allow bank employees to view all the transactions that have been made in a given time period.

Test the system: Before releasing your banking transaction system, you should thoroughly test it to make sure that it works as expected. Write test cases for each method, and make sure that they all pass.
Here is some sample code to get you started:
csharp
Copy code
public class Bank {
private ArrayList<Account> accounts;
public Bank() {
accounts = new ArrayList<>();
}
public void addAccount(Account account) {
accounts.add(account);
}
public ArrayList<Account> getAccounts() {
return accounts;
}
public void transferMoney(Account from, Account to, double amount) {
from.withdraw(amount);
to.deposit(amount);
}
}
public class Account {
private int accountNumber;
private String accountHolder;
private double balance;
public Account(int accountNumber, String accountHolder) {
this.accountNumber = accountNumber;
this.accountHolder = accountHolder;
balance = 0;
}
public int getAccountNumber() {
return accountNumber;
}
public String getAccountHolder() {
return accountHolder;
}
public double getBalance() {
return balance;
}
public void deposit(double amount) {
balance += amount;
}
public void withdraw(double amount) {
balance -= amount;
}
}
public class Transaction {
private Account from;
private Account to;
private double amount;
private Date date;
public Transaction(Account from, Account to, double amount) {
this.from = from;
this.to = to;
this.amount = amount;
date = new Date();
}
public Account getFrom() {
return from;
}
public Account getTo() {
return to;
}
public double getAmount() {
return amount;
}
public Date getDate() {
return date;
}
}
With these basic classes, you can add additional functionality as needed, such as methods to handle interest calculations, account creation and deletion, and transaction history tracking.
