java - 如何更改不同类的字符串数组的值？

Question

这可能是一个非常简单的问题，但我似乎无法在 Google 上找到合适的答案。我有一个名为 Player 的类，它有一个名为 playerInv 的字符串数组，大小为 10。

在我的主 Activity 类中，我想运行 for 循环来确定数组中第一个为空的索引 ("")。然后我想用一个新字符串填充它，然后终止循环。我该怎么做呢？

很抱歉问了这个菜鸟问题。就像我说的，我尝试过 Google，但没有成功!

For 循环:

    String playerInvTemp[] = thePlayer.getPlayerInv; ERROR -- cannot resolve getPlayerInv
                for (int i=0; i < playerInvTemp.length; i++)
                {
                    if ((!playerInvTemp[i].isEmpty()) || playerInvTemp[i] == null)
                    {
                        setPlayerInv("Blood Essence", i); ERROR cannot resolve setPlayerInv
                        //invText.setText();
                        Blood = true;
                        break;
                    }
                }

公共(public)类玩家{

private int playerPos;
private int playerHP;
private String playerInv[];

Player(int startPos, int startHP, String[] newInventory)
{
    playerPos = startPos;
    playerHP = startHP;
    playerInv = newInventory;
}
public int getPlayerPos() {
    return playerPos;
}

public void setPlayerPos(int playerPos) {
    this.playerPos = playerPos;
}

public int getPlayerHP(){
    return playerHP;
}

public void setPlayerHP(int playerHP){
    this.playerHP = playerHP;
}

public String getPlayerInv(int pos)
{
    return playerInv[pos];
}

public void setPlayerInv(String playerInv[]) {
    for (int i=0; i<10; i++)
    {
        this.playerInv[i] = playerInv[i];
    }
}

public void setPlayerInv(String val, int index)
{
    this.playerInv[index] = val;
}

public String getPlayerInv()
{
    return this.playerInv;  *//this gives error "Incompatible types. Required java.lang.string, found java.lang.string[]"*
}

}

这样做

在Player类中添加这两个方法

public void setPlayerInv(String val, int index) 
{
    this.playerInv[index] = val;
}

public String[] getPlayerInv()
{
    return this.playerInv;
}

然后像这样改变你的for循环

String playerInvTemp[] = thePlayer.getPlayerInv();
for (int i=0; i < playerInvTemp.length; i++)
{
    if (!playerInvTemp[i].isEmpty()) || playerInvTemp[i] == null)
    {
        setPlayerInv("Blood Essence", i);
        //invText.setText();
        Blood = true;
        break;
    }
}
