Java: Fields and State
Answer
Fields are object state; local variables are temporary and method-specific.
Fields maintain the object's state throughout its lifetime, while local variables are temporary, existing only during method execution. For instance, a 'totalPrice' field in CartItem persists as long as the object exists, whereas a local variable in a method calculating a discount is discarded after use.
