Assume that variable myNumber is declared and initialized. Which line(s) of the following code will create a syntax error? Explain each error briefly. int my Number = 21; switch (myNumber): { case (myNumber >= 0) System.out.print("myNumber is 21"); break; case 210 System.out.print("myNumber is 210"); break; case 44.0: System.out.print("myNumber is 44.0"); break; case 66: System.out.print("myNumber is 6"); break; case 100/2: System.out.print("myNumber is 50"); break; default: System.out.print("something else"); break; Assume that letter and selection variables are already declared and initialized. Convert the following conditional statements to switch statement. if ( letter == 'A' || letter == 'B' || letter == 'C') 10 11 12 13 selection "Yes"; 14 else if ( letter == 'F') selection = "No"; 15 16 17 18 19 20 else selection = "Maybe"; Will the following code run for the user inputs 5 and 4 ? explain why or why not. public static void main(String[] args) { 2. 3. 4. 5. 6. 7. int num; int item; Scanner input = new Scanner(System.in); System.out.println("Enter a number:"); num = input.nextInt(); System.out.println("Enter item:"); item input.nextInt(); = 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. if (num >0 && num
