значения объекта не меняются Java Массив

Question

Привет, я пытаюсь изменить значения объектов в моем массиве, таких как State, с "idle" на "ready". Но когда я запускаю свой код, он изначально печатает новое значение, но затем, когда я пытаюсь снова распечатать массив, он возвращается к исходным значениям? вот часть кода, спасибо :)

public class PumpSystem {


private Pumps station[];
Scanner stdin = new Scanner(System.in);
Attendant attendant = new Attendant();



public PumpSystem() {
    station = new Pumps[10];


    station[0] = new Pumps("P101", "Idle", "Default", 0.0, 0.0, 0.0);
    station[1] = new Pumps("P102", "Idle", "Default", 0.0, 0.0, 0.0);
    station[2] = new Pumps("P103", "Idle", "Default", 0.0, 0.0, 0.0);
    station[3] = new Pumps("P104", "Idle", "Default", 0.0, 0.0, 0.0);
    station[4] = new Pumps("P105", "Idle", "Default", 0.0, 0.0, 0.0);
    station[5] = new Pumps("P201", "Idle", "Default", 0.0, 0.0, 0.0);
    station[6] = new Pumps("P202", "Idle", "Default", 0.0, 0.0, 0.0);
    station[7] = new Pumps("P203", "Idle", "Default", 0.0, 0.0, 0.0);
    station[8] = new Pumps("P204", "Idle", "Default", 0.0, 0.0, 0.0);
    station[9] = new Pumps("P205", "Idle", "Default", 0.0, 0.0, 0.0);


}


//************** Print-Stations ***********************
public void printStations() {
    for (int i = 0; i < station.length; i++) {
        System.out.println(" ID: " + station[i].getPumpID() + " --> " + " State: " + station[i].getState());
    }
}

//*********************** Switch statement for Statues change ************************************


public void updateModeSelect() {
    boolean endLoop = false;


    while (!endLoop) {
        menu();
        int option = stdin.nextInt();
        String wait = stdin.nextLine();
        switch (option) {
            case 0:
                System.out.println(" **** Enter new State **** \n");
                station[0].setState(stdin.nextLine() + "\n");
                System.out.println("Station: P101 State changed to: " + station[0].getState());
                attendant.attendantControls();
            case 1:

, и я получаю следующий результат:

     **** Enter new State **** 

Ready  <-- user input

Station: P101 State changed to: Ready

  
*** Logged in as Attendant  ***  
  (1) *** Stations ***
  (2) *** Change Pump State ***  
  (3) *** back to Main Menu *** 
  (4) *** Shut Down *** 

так что он работает, но затем я распечатываю свой массив и его обратно в режим ожидания? это мой класс Pump

public class Pumps {

    private String pumpID;
    private String state;
    private String fuelType;
    private double total;
    private double pumpOutPut;
    private double pumpInTake;



    //Constructors
    public Pumps ( String pumpID, String state, String fuelType, double total ,
                 double pumpOutPut, double pumpInTake){
        this.pumpID = pumpID;
        this.state =  state;
        this.fuelType = fuelType;
        this.total = total;
        this.pumpOutPut = pumpOutPut;
         this.pumpInTake = pumpInTake;

    }

    public String getPumpID() {
        return pumpID;
    }

    public void setPumpID(String newPumpID) {
        pumpID = newPumpID;
    }

    //*************MODE*********************

    public void setState(String newState) {
         state = newState;

    }



    public String getState() {
        return state;
    }

    //*************FUEL-TYPE*********************

    public void setFuelType(String newFuelType) {
        fuelType = newFuelType;
    }

    public String getFuelType() {
        return fuelType;
    }
    //*************PUMP-IN-TAKE*********************


    public void setPumpInTake(double newPumpInTake) {
        pumpInTake = newPumpInTake;
    }


    //**************PUMP-OUT-PUT********************
    public void setPumpOutPut(double newPumpOutPut) {
        pumpOutPut = newPumpOutPut;
    }

    //*************TOTAL*********************

    public void setTotal(double newTotal) {
        total = newTotal;
    }



    @Override
    public String toString() {
        return pumpID +state + fuelType + total + pumpInTake + pumpOutPut;
    }
        //**********************************
}

это то, что дежурный делает с serveantControls ()

import java.util.Scanner;

public class Attendant {


    public void attendantControls(){

        Scanner stdin = new Scanner(System.in);
        Main main = new Main();
        boolean endLoop = false;
        Manager manager = new Manager();
        PumpSystem pumpSystem =  new PumpSystem();

        while (!endLoop) {
            menu();
            int selection = stdin.nextInt();
            switch (selection) {
                case 1:
                    System.out.println("*** Stations *** ");
                    pumpSystem.printStations();
                    System.out.println("*************************************************");



                    break;
                case 2:
                    System.out.println("*** Pump State Managment ***");
                    pumpSystem.updateModeSelect();
                    System.out.println("*************************************************");
                    System.out.println("*************************************************");
                    break;
                case 3:
                    System.out.println("*** Main Menu ***");
                    endLoop = true;
                default:
                    System.out.println("Invalid Input - Please Select Options  1-3");
                    break;
            }
        }
    }


    private  void menu() {
        System.out.println("  \n*** Logged in as Attendant  ***  ");
        System.out.println("  (1) *** Stations ***");
        System.out.println("  (2) *** Change Pump State ***  ");
        System.out.println("  (3) *** back to Main Menu *** ");
        System.out.println("  (4) *** Shut Down *** ");

    }
}
