Project Overview

Practice Java classes, objects, methods, and encapsulation by building a bank account app.

This beginner Java project helps you practice real coding skills with a small program you can run, edit, and improve.

Java Code

class BankAccount {
  private double balance;
  public void deposit(double amount) { balance += amount; }
  public void withdraw(double amount) {
    if (amount <= balance) balance -= amount;
  }
  public double getBalance() { return balance; }
}

public class Main {
  public static void main(String[] args) {
    BankAccount account = new BankAccount();
    account.deposit(100);
    account.withdraw(40);
    System.out.println(account.getBalance());
  }
}
