What is the performance of switch-case statements in programming?

What is the performance of switch-case statements compared to if-else statements?

Switch-case statements can be more efficient than if-else chains, especially with many conditions, due to better optimization.

Are there specific scenarios where switch-case is preferred?

Yes, switch-case is preferred when dealing with multiple discrete values, like menu selections or command processing.

Does the performance vary by programming language?

Yes, the performance of switch-case can vary significantly between languages due to different compiler optimizations.

Can you give an example of a switch-case 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";
}
