ANSWER:

switch (expression) {

case value1:

// code to be executed if

// expression is equal to value1

break;

case value2:

// code to be executed if

// expression is equal to value2

break;

...

...

default:

// default statements

}

How does the switch statement WORK?

The expression is evaluated once and compared with the values of each case LABEL.

If there is a match, the corresponding code after the matching case label is executed.

For example, if the value of the expression is equal to value2, the code after case value2: is executed.

If there is no match, the code after default: is executed.

Note: We can do the same functionality using the Java if...else...if LADDER. However, the syntax of the switch statement is cleaner and much easier to read and write.

Example 1: Java switch statement

// Java Program to check the size

// using the switch...case statement

class Main {

public static void main(String[] args) {

int number = 44;

String size;

// switch statement to check size

switch (number) {

case 29:

size = "Small";

break;
