bagamana jika nilai yang di input sama dengan nilai yang ada didalam array akan mencetak kalimat ?

                                System.out.println("data salah");
                            }
                            break;
                        case "Deluxe":

                            break;
                        default:
                            System.out.println("Silahkan pilih jenis kamar kembali");
                    }
                    break;
                case 3:

                    break;
                case 4:
                    System.exit(0);
                    break;
                default:
                    System.out.println("Data tidak ditemukan..");
            }
        } while (pilihan != 4);
    }

}

jadi jika kita menginputkan nomor dan nilai nomor tadi sama dengan hasil math.random yang tersimpan didalam array tadi, akan mencetak nama, nomor identitas, dan sebagainya.
