Note:-Switch case provides built-in multiway decision statement.It switches to statement by testing the value.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class SwitchTest {
         public static void main(String [] args) throws IOException{
             int days= 0;
         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
         System.out.println("Enter The Number");
            String data = br.readLine();
            days=  Integer.parseInt(data);

             switch(days){

             case 1: System.out.println("Sunday");
             break;
             case 2:  System.out.println("Monday");
             break;
             case 3:  System.out.println("Tuesday"); 
             break;
             case 4:  System.out.println("Wednesday"); 
             break;
             case 5:  System.out.println("Thursday");
             break;
             case 6:  System.out.println("Friday");
             break;
             case 7:  System.out.println("Saturday");
             break;
            default: System.out.println("Invalid days.");
             break;
         }
     }
}

Output

Enter the number 
3
Tuesday

Description: - In this example, we are using switch case statement. The program displays the name of the days according to user choice. As we inputted 3 so it switches to the case 3 and prints the value of case 3.
