Switch Statements – Introduction to Programming

Can switch on any byte, short, int, char, String and enumeration.
Note: can not switch on long or floating point numbers
Equivalent to if-else if ladder
More efficient that if-else if ladder in many cases

int count = kb.nextInt();
double price = 0;
double taxRate;

switch(count) {
    case 1:
    price = 1.0;
    taxRate = 2.0;
    break;

    case 2:
    price = 0.75;

    case 3:
    if (price == 0)
        price = 0.5;
    taxRate = 1.25;
    break;

    default:
    price = 0.25;
    taxRate = 1.0;
}

Equivalent if-else if ladder

if (count == 1) {
    price = 1.0;
    taxRate = 2.0;
} else if (count == 2) {
    price = 0.75;
    taxRate = 1.25;
}
else if (count == 3) {
    price = 0.5;
    taxRate = 1.25;
}
else {
    price 0.25;
    taxRate = 1.0;
}
