Привет
У меня есть проблема , я хочу ,когда пользователь вводит 1, затем добавить символ x, а затем, если добавить символ r
Я хочу вернуться к этому списку

System.out.println("-------------------------------------");
                System.out.println("***             RIDES             ***");
                System.out.println("-------------------------------------");
                System.out.println("| X or x : UberX                    |");
                System.out.println("| L or l : UberXL                   |");
                System.out.println("| B or b : UberBlack                |");
                System.out.println("-------------------------------------");
                System.out.print(" > Please enter your choice...");
                UberX = t.next().charAt(0);

Что я уже пробовал:

while (cho == 1) {

                System.out.println("-------------------------------------");
                System.out.println("***             RIDES             ***");
                System.out.println("-------------------------------------");
                System.out.println("| X or x : UberX                    |");
                System.out.println("| L or l : UberXL                   |");
                System.out.println("| B or b : UberBlack                |");
                System.out.println("-------------------------------------");
                System.out.print(" > Please enter your choice...");
                UberX = t.next().charAt(0);

                while (UberX == 'x') {
                    System.out.println("-------------------------------------");
                    System.out.println("***            OPTIONS            ***");
                    System.out.println("-------------------------------------");
                    System.out.println("| B or b:  Base fare                |");
                    System.out.println("| M or m:  Cost per minute          |");
                    System.out.println("| K or k:  Cost per km              |");
                    System.out.println("| S or s:  Service fee              |");
                    System.out.println("| C or c:  Cancellation fee         |");
                    System.out.println("| F or f:  Minimum fee              |");
                    System.out.println("| R or r:  Previous Menu            |");
                    System.out.println("-------------------------------------");
                    System.out.print(" > Please enter your choice...");
                    cho = t.next().charAt(0);

                    while (cho == 'b' || cho == 'B') {
                        System.out.println("Base fare for UberX is " + "3.2SR");
                        break;
                    }

                    while (cho == 'm' || cho == 'M') {
                        System.out.println("Cost per minute for UberX is " + "0.25SR");
                        break;
                    }

                    while (cho == 'k' || cho == 'K') {
                        System.out.println("Cost per km for UberX is " + "0.9SR");
                        break;
                    }

                    while (cho == 's' || cho == 'S') {
                        System.out.println("Service fee for UberX is " + "0SR");
                        break;
                    }
                    while (cho == 'c' || cho == 'C') {
                        System.out.println("Cancellation fee for UberX is " + "8SR");
                        break;
                    }

                    while (cho == 'f' || cho == 'F') {
                        System.out.println("Minimum fee for UberX is " + "8SR");
                        break;
                    }

                    while (cho == 'r' || cho == 'R') {
                        break;
                    }
                    
                    break;
                }
               break;
            }
