Java: Scope and Reassignment
Answer
A local variable exists only within the method or block where it's declared.
Local variables are created when the method is called and destroyed when the method exits. This is important in e-commerce functions like calculating discounts: once the calculation is done, the variable disappears, ensuring no leftover data affects future calculations.
