java enum in switch statement

In Java, you can use an enum type in a switch statement to control the flow of execution based on the value of the enum.

Here's an example of how to use an enum in a switch statement in Java:

public enum Size {
    SMALL("S"), MEDIUM("M"), LARGE("L"), EXTRA_LARGE("XL");

    private String abbreviation;

    private Size(String abbreviation) {
        this.abbreviation = abbreviation;
    }

    public String getAbbreviation() {
        return abbreviation;
    }

    public static void main(String[] args) {
        Size size = Size.LARGE;

        switch (size) {
            case SMALL:
                System.out.println("The size is small");
                break;
            case MEDIUM:
                System.out.println("The size is medium");
                break;
            case LARGE:
                System.out.println("The size is large");
                break;
            case EXTRA_LARGE:
                System.out.println("The size is extra large");
                break;
        }
    }
}

In this example, the Size enum has four constant values: SMALL, MEDIUM, LARGE, and EXTRA_LARGE. The main() method defines a Size variable called size and assigns it the value LARGE.

The switch statement checks the value of the size variable, and executes the code in the corresponding case block based on the value of the enum. In this example, the code in the LARGE case block is executed, and the message "The size is large" is printed.

You can use an enum in a switch statement in the same way as you would use any other type. Just specify the enum type in the switch statement and use the enum constant values as the case labels.
