Building a Simple Banking App

Bringing Java to Life

Imagine you want to track your savings and withdrawals. A banking app is a fantastic project to practice your Java skills!

Requirements

  • Store account holder information (name, balance).
  • Allow deposits and withdrawals.
  • Show the balance.

Sample Code

public class BankAccount {
  String name;
  double balance;

  void deposit(double amount) {
    balance += amount;
  }

  void withdraw(double amount) {
    if (balance >= amount) {
      balance -= amount;
    }
  }

  void displayBalance() {
    System.out.println("Balance: $" + balance);
  }
}

Real-World Impact

These skills are used in apps that manage money, track expenses, and even in ATMs!

Examples

  • Creating a BankAccount class with deposit and withdraw methods.

  • Simulating transactions and displaying updated balances.
