In Java, a switch statement is used for decision-making based on the value of an expression. It allows you to test the value of a variable or expression against multiple possible constant values. Here’s the basic syntax of a switch statement:
switch (expression) {
case value1:
// code to be executed if expression matches value1
break;
case value2:
// code to be executed if expression matches value2
break;
// more cases as needed
default:
// code to be executed if none of the cases match
}Code language: JavaScript (javascript)Here’s a simple example using a switch statement to determine the day of the week based on a numeric code:
public class SwitchExample {
public static void main(String[] args) {
int dayOfWeek = 3;
switch (dayOfWeek) {
case 1:
System.out.println("Monday");
break;
case 2:
System.out.println("Tuesday");
break;
case 3:
System.out.println("Wednesday");
break;
case 4:
System.out.println("Thursday");
break;
case 5:
System.out.println("Friday");
break;
case 6:
System.out.println("Saturday");
break;
case 7:
System.out.println("Sunday");
break;
default:
System.out.println("Invalid day of the week");
}
}
}Here’s another simple example using a switch statement to determine the Telugu Season based on a numeric code
import java.util.Scanner;
public class TeluguSeasons {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a month (1-12): ");
int month = scanner.nextInt();
String season;
switch (month) {
case 1:
case 2:
season = "Hemanta (Late Autumn/Winter)";
break;
case 3:
case 4:
season = "Shishira (Pre-Spring)";
break;
case 5:
case 6:
season = "Vasanta (Spring)";
break;
case 7:
case 8:
season = "Grishma (Summer)";
break;
case 9:
case 10:
season = "Varsha (Rainy)";
break;
case 11:
case 12:
season = "Sharad (Autumn)";
break;
default:
season = "Invalid month";
break;
}
System.out.println("The Telugu season for month " + month + " is " + season);
scanner.close();
}
}
