Java Switch Case Statements

Switch Case-Control Instruction

  • Switch-Case is used when we have to make a choice between the number of alternatives for a given variable.

  • Var can be an integer, character, or string in Java.

  • Every switch case must contain a default case. The default case is executed when all the other cases are false.

  • Never forget to include the break statement after every switch case otherwise the switch case will not terminate.

  • Syntax:

     Switch(var) {
    	Case C1:
    	Case C2:
    	Case C3:

  • A switch can occur within another but in practice, this is rarely done.

  • Flow control of switch case in Java :


    import java.util.Scanner;
    public class cwh_18_elseif {
        public static void main(String[] args) {
            String var = "Saurabh";
            switch (var) {
                case "Shubham" -> {
                    System.out.println("You are going to become an Adult!");
                    System.out.println("You are going to become an Adult!");
                    System.out.println("You are going to become an Adult!");
                case "Saurabh" -> System.out.println("You are going to join a Job!");
                case "Vishaka" -> System.out.println("You are going to get retired!");
                default -> System.out.println("Enjoy Your life!");
            System.out.println("Thanks for using my Java Code!");


    You are going to join a Job!
    Thanks for using my Java Code!
