How can I implement a switch case in different programming languages?

Can you explain how to use switch case in Java?

Sure! In Java, a switch case statement allows you to execute different parts of code based on the value of a variable. 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 about in Python? Does it have a switch case?

Python doesn't have a built-in switch case statement, but you can achieve similar functionality using dictionaries or if-elif-else statements. Here's an example using a dictionary:

def switch_case(day):
    return {
        1: "Monday",
        2: "Tuesday",
        3: "Wednesday"
    }.get(day, "Invalid day")

print(switch_case(3))

How is it done in JavaScript?

In JavaScript, you can use the switch statement similarly to Java. Here's an example:

let day = 2;
let dayName;
switch (day) {
    case 1:
        dayName = "Monday";
        break;
    case 2:
        dayName = "Tuesday";
        break;
    case 3:
        dayName = "Wednesday";
        break;
    default:
        dayName = "Invalid day";
}
console.log(dayName);
