What happens when you use a switch statement with an integer variable representing shipping zones to apply specific fees?
Multiple choiceMediumchapter-1-curatedpremiumcore-javaconditions-and-branching
int shippingZone = 2;
switch (shippingZone) {
case 1: applyFee(5); break;
case 2: applyFee(10); break;
case 3: applyFee(15); break;
}Answer and explanation
Correct answer
B. All cases execute unless a break is used.
Why
Switch statements execute all subsequent cases after a match unless a break is encountered. This behavior allows for 'fall-through' to execute multiple blocks but usually requires breaks to prevent unintended execution.
