java hirerequest() и методы processhirerequest()

Question

Привет, ребята, я создал два разных класса, которые являются классом shopitem и классом shopuser. Мне нужно создать два метода: hirerequest() и processhirerequest: ниже моя попытка кодирования, которая был несовместим и не скомпилирован:

/** 
    * Accessor method hireRequest 
    * 
    * @return shopuser and shopitem object's 
    */ 
    public String hireRequest() 
    { 
     return shop item object; 
     return shop user object; 
    } 



/** 
    * Accessor method processHireRequest 
    * 
    * @return name 
    */ 
    public String processHireRequest() 
    { 
     return hireRequest; 
    } 

это код выше, правильный и должен ли он работать?

любые ответы или помощь были бы весьма полезными.

код Shopitem:

public abstract class ShopItem

    private ArrayList<Tool> toolsList; 
    Shop shop; 
    private int toolCount;

    private String ElectricTool; 
    private String HandTool; 
    private String Perishable; 
    private String Workwear; 
    private boolean ShopUserID; 


    public void ReadToolData (String data) throws FileNotFoundException,NoSuchElementException

Answer 1

public String hireRequest() { 
    return shop item object; 
    return shop user object; 
} 

Метод может возвращать только один элемент.

Пользовательский объект магазина никогда не вызывается. У вас должны быть отдельные геттеры для shopUser и shopItem.
