Control Structures

2. Switch Statement

Selects one of many code blocks to execute based on the value of an expression (typically an int, char, String, or enum).

Syntax (Java 7+ for String):

switch (expression) {

    case value1:

        // Code

        break;

    case value2:

        // Code

        break;

    default:

        // Code if no case matches

}

Example:

public class SwitchExample {

    public static void main(String[] args) {

        String day = "Monday";

        switch (day) {

            case "Monday":

                System.out.println("Start of the week"); // Output: Start of the week

                break;

            case "Friday":

                System.out.println("End of the work week");

                break;

            default:

                System.out.println("Midweek or weekend");

        }

    }
