Java: Scope and Reassignment
Answer
Shadowing occurs when a variable in a local scope has the same name as one in an outer scope.
Shadowing can cause confusion because the inner variable hides the outer one. In an e-commerce checkout, if you accidentally shadow a 'totalPrice' variable, it might lead to unexpected calculations, since you might think you're modifying the outer variable, but you're not.
