Submitted by Nidhi, on March 02, 2022

Problem Solution:

In this program, we will read an integer number for a weekday and print the corresponding weekday using a switch statement.

Program/Source Code:

The source code to read a weekday number and print a weekday name using a switch statement is given below. The given program is compiled and executed successfully.

// Java program to read a weekday number and 
// print weekday name using switch statement

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner SN = new Scanner(System.in);
    int wDay = 0;

    System.out.printf("Enter weekday number (0-6): ");
    wDay = SN.nextInt();

    switch (wDay) {
    case 0:
      System.out.printf("Sunday");
      break;

    case 1:
      System.out.printf("Monday");
      break;

    case 2:
      System.out.printf("Tuesday");
      break;

    case 3:
      System.out.printf("Wednesday");
      break;

    case 4:
      System.out.printf("Thursday");
      break;

    case 5:
      System.out.printf("Friday");
      break;
    case 6:
      System.out.printf("Saturday");
      break;

    default:
      System.out.printf("Invalid weekday number.");
    }
    System.out.printf("\n");
  }
}

Output:

Enter weekday number (0-6): 5
Friday

Explanation:

In the above program, we imported the "java.util.Scanner" package to read input from the user. And, created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we read an integer number for a weekday using Scanner class. Then we printed the corresponding weekday.
