What is the purpose of a switch statement in programming?

A switch statement allows you to execute different parts of code based on the value of a variable, making it cleaner than 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;
String dayName;
switch (day) {
    case 1:
        dayName = "Monday";
        break;
    case 2:
        dayName = "Tuesday";
        break;
    case 3:
        dayName = "Wednesday";
        break;
    default:
        dayName = "Invalid day";
}
System.out.println(dayName);

What are the advantages of using a switch statement?

Switch statements can improve code readability and performance when dealing with multiple conditions, especially with many cases.

Are there any limitations to using switch statements?

Yes, switch statements can only evaluate expressions that result in a single value, and they don't support ranges or complex conditions.
