i am very new in java. i am having problem in SWITCH CASE STATEMENT. can anyone please help me to solve the following problem:

you have to write a program in java to generate the following menu with submenus:

LinkedList

1: ADD ELEMENT
1-1: add first
1-2: add last
1-3: back to main menu

2: REMOVE ELEMENT
2-1: remove first
2-2: remove in between
2-3: remove last
2-4: back to main menu

3: OTHER FUNCTIONS
3-1: peek first
3-2: peek last
3-3: poll first
3-4: poll last
3-5: back to main

4: DISPLAY

5. EXIT

                        case 1: System.out.println("Add First: "); lst.addFirst;
                                break;
                        case 2: lst.addLast;
                                break;
                        case 3: 
                    }
            case 2: menuB();
                    break;
            case 3: menuC();
                    break;
            case 4: System.out.println(lst);
                    break;
            case 5: System.exit();
        }
   }
   
}

It is incomplete. Im not finish this yet. I hope you can have any suggestions.

You are going right here such a menu would require a nested switch implementation which you are on your way to do, so what are the errors you are getting and where do you need our help ?
