Getting Started

When starting any of these projects, it's helpful to break them down into smaller components. For example, if you're making a banking system, you might first design the account class, then implement methods for depositing and withdrawing money. BlueJ's visual representation of classes and objects can help you understand the relationships between different components, making it a great tool for learning Java programming concepts.
