what is wrong in following code in Java (Switching cases)?


package ifelse; import java.util.Scanner; import java.util.*;  public class SwitchCasese {     public static void main(String[] args) {         Scanner sc = new Scanner (System.in);         System.out.println("enter your day ");         String day = sc.nextLine();         String result;                  switch (day){         case "monday ":             result = "working";             break;         case "Tuesday":             result = "Studying";             break;         case "wednesday":             result = "riding";             break;                                   }            System.out.println(result );                            }  } ```
