如何在另一个类Java中将对象添加到数组中

Question

这是我的代码：

public class One
{
 //Loots is a class  
   public static Loots[] lootsList = new Loots[] { };
}   

public class Two
{ 
   Loots MyLoots = new Loots();         
   // How to add in THIS class, MyLoots to lootsList? 
}

请帮帮我 我不想使用List！

Answer 1

访问静态变量和另一个类的方法

ClassName.StaticVariable;

或

ClassName.StaticMethod;

注意： - 静态变量和方法在整个应用程序中都处于活动状态。

使用此

public class One
    {
       public static Loots[] lootsList = new Loots[1];
    }   

    public class Two
    { 
       Loots MyLoots = new Loots();         
       // How to add in THIS class, MyLoots to lootsList? 
       One.Loots[0]=MyLoots; //use this to access array of objects
    }

享受编码.........

Answer 2

public class One{
   public List<Loots> lootsList = new ArrayList<Loots>();

   public void someVoid(){
       new Two(this);
   }
}   

public class Two
{ 
    One one;
    public Two(One one){
        this.one = one:
    }

   Loots MyLoots = new Loots();         
   // How to add in THIS class, MyLoots to lootsList? 

    public void someVoid(){
        one.lootsList.add(MyLoots);
    }

}

这是一种更好的方法，因为ArrayList可以根据需要保存任意数量的对象，而不需要通过列表的初始化来定义。

通过像你一样定义它，数组中必须有特定数量的Loots max。

替代：

public static Loots[] lootsList = new Loots[20];

示例：

public class One{

    public static Loots[] lootsList = new Loots[20];
    public void someVoid(){
       new Two(this);
    }
}   

public class Two
{ 
    One one;
    public Two(One one){
        this.one = one:
    }

   Loots MyLoots = new Loots();         
   // How to add in THIS class, MyLoots to lootsList? 

    public void someVoid(){
        one.lootsList[0].add(MyLoots);
    }

}
