为什么我收到堆栈溢出?

2022-04-12 00:00:00 stack-overflow java

我的第一个代码块是我的Item对象文件;第二个是Main Class。在代码运行之前没有任何问题,但是在我添加了一个读写文件之后,我的代码开始接收到堆栈流错误。只是正在调用其错误的代码段。

    public class Item implements java.io.Serializable {

    public static String name;
    public static double price;
    public static double amount;
    public int max = 1;
    SlayerProgram sp = new SlayerProgram();
    ReadFile rf = new ReadFile();
    public Item(String name, double price,double amount )
    {
    this.name = name;
    this.price = price;
    this.amount = amount;

    }

    public void ItemSet(String name, double price,double amount)
    {
    this.name = name;
    this.price = price;
    this.amount = amount  
    }

我的主类:

    public class SlayerProgram {
//import file txts, and Item Class

        static String name;
        static double price;
        static double amount;
 Item item = new Item(name,price,amount);
ReadFile rf = new ReadFile();
static String fileNameText = "D:\Game\SlayerProgram\Name.txt";
static String filePriceInt = "D:\Game\SlayerProgram\Price.txt";
static String fileAmountInt ="D:\Game\SlayerProgram\Amount.txt";

   //begin file Read   

public void BeginText() throws IOException
{
    TextFile();
}

public void Max()
{
    item.Max();
}

    //declare needed Data Types;
        final int max = item.max;
        ArrayList<String> Name  = new ArrayList<>();
        ArrayList<Double> Price = new ArrayList<>();
        double size = Price.size();
        ArrayList<Double> Amount = new ArrayList<>();


Exception in thread "main" java.lang.StackOverflowError
at slayerprogram.Item.<init>(Item.java:18)
at slayerprogram.SlayerProgram.<init>(SlayerProgram.java:25)
at slayerprogram.Item.<init>(Item.java:18)
at slayerprogram.SlayerProgram.<init>(SlayerProgram.java:25)

如何找到导致堆栈溢出的位置?


解决方案

Item创建SlayerProgram

SlayerProgram sp = new SlayerProgram();

SlayerProgram创建Item

Item item = new Item(name,price,amount);

因此在初始化时,您将无休止地创建这些对象

获取StackOverflow Error有类似的Baeldung example

这以StackOverflow Error结束,因为ClassOne的构造函数实例化ClassTwo,而ClassTwo的构造函数再次实例化ClassOne。
