Java 无法从零件[]转换为零件

首先，让我解释一下我想做什么。在java中，我正在创建一个与我高中的一个cca程序相关的游戏，我正在用vb6制作（已经很好地使用了），但我只能在其中做些什么，所以我正在使用java。名为Parts的类的代码如下所示：

public class Parts implements Cloneable{
    public static Parts[] PartsList = new Parts[4096];
    public static HashMap<Integer,Boolean> ArrayList = new HashMap<Integer,Boolean>();
    protected boolean PartConstructerCalled = false;
    public int partTextureIndex;
    public final int partID;
    protected float partStat;
    protected String partConversion;
    private String partName;
    /**
     * To get everything started.
     */
    public static void Init_Parts(){}
    public Object clone() throws CloneNotSupportedException{
        return super.clone();
    }
    /**
    * Call this to create a new part.
    * Game crashes if an id you give is already used.
    * @param id Id to give to the part.
    */
    public Parts(int id, int textureid)
    {
        this.PartConstructerCalled = true;
        if(PartsList[id] != null){
            Variables.HackLog.severe("Part id of " + id + " is already used.");
            String partname = PartsList[id].getPartName();
            if(partname != "Un-named"){
                throw new IllegalArgumentException("id " + String.valueOf(id) + " was trying to take up part id of " + id + " which is already taken up by "+PartsList[id].getPartName() + ".");
            }else{
                    throw new IllegalArgumentException("id " + String.valueOf(id) + " was trying to take up part id of " + id + " which is already used.");
                }
        }else{
            this.partID = id;
            this.partName = "Un-named";
            this.partTextureIndex = textureid;
                PartsList[id] = this;
                ArrayList.put(id, false);
        }
    }
}

rarray

属于

Parts[]

类型，它是Parts对象数组。您正在尝试将其转换为单个

部分
对象。你认为这是怎么做到的？您可以从数组中获取某些元素，并将其分配给某些
部分
对象，例如
部分列表[id]=rarray[0]
。但这只是一个例子，我真的不知道你想在这里分配什么。
你有一个数组，你想要一个元素。。。那么，您想要哪个元素，以及您希望转换如何工作？为什么
array
是一个数组？（这段代码确实不清楚您想要实现什么。）除了给出错误的代码外，这两段代码片段似乎是相同的。区别是什么？他的Parts[]rarray不是在if-else语句中吗？因此，当它存在时，该语句被销毁，因此rarray[0]不再存在了？哎呀，我的坏，好久没见了。Nevermind:）+1
PartsList[id]=（Parts）rarray也在
else
中，比如
Parts[]rarray=…
Nvm为了满足我的需要，我不得不将Parts[4096]的定义更改为Parts[4096][]，或者是Parts.java中的Parts[4096][4096]

Type mismatch: cannot convert from Parts[] to Parts
