What are switch statements and how do I use them?

Switch statements are a control structure that allows you to execute different parts of code based on the value of a variable. They are often used as an alternative to multiple if-else statements.

Can you give me an example of a switch statement in Java?

Sure! Here's a simple example:

int day = 3;
switch (day) {
    case 1:
        System.out.println("Monday");
        break;
    case 2:
        System.out.println("Tuesday");
        break;
    case 3:
        System.out.println("Wednesday");
        break;
    default:
        System.out.println("Invalid day");
}

What happens if I forget the break statement?

If you forget the break statement, the code will continue to execute into the next case, which is known as 'fall-through'. This can lead to unexpected behavior.

Are there any limitations to using switch statements?

Yes, switch statements can only evaluate expressions that result in a single value, like integers, characters, or strings, depending on the programming language.
