Java stackOverFlow错误对象编码方式错误

Question

我正在从事运输地图的项目。 我为该位置创建了一个名为Chart的对象和一个名为Pos的对象。 我无法工作的是，当我从文本文件中读取图表以正确创建对象Pos时，因为那是失败的地方。

现在是Pos班级

 private Pos Pos;

 public Pos(int d, int m, int t){
      Pos pos = new Pos(d,m,t);
 }

现在是Chart类

private String title;
private String colorString;
private String scale;
private String edition;
private Pos north;
private Pos south;
private Pos west;
private Pos east;

private Chart Chart;

public Chart(Pos north, Pos south, Pos west, Pos east, String color, String scale, String edition, String title){
    Chart = new Chart(north, south, west, east, color, scale, edition, title);
}

现在这里是我希望代码创建图表的地方。 我已经做了很多小步骤来确保输出正确：

In in;
    String fileName = "charts.txt";
    int aantalKaarten;
    int kolommen;
    String[][] tabel;
    int n1,n2,n3,s1,s2,s3,w1,w2,w3,e1,e2,e3;
    String color;
    String edition;
    String scale;
    String title;

    in = new In(fileName);
    aantalKaarten = in.readInt()+1;
    for(int i = 0;i < aantalKaarten;i++){
        try {
            n1 = in.readInt();
            n2 = in.readInt();
            n3 = in.readInt();
            System.out.println("Noordelijke lengtegraad: " + n1 + ", " + n2 + ", " + n3);
            s1 = in.readInt();
            s2 = in.readInt();
            s3 = in.readInt();
            System.out.println("Zuidelijke lengtegraad: " + s1 + ", " + s2 + ", " + s3);
            w1 = in.readInt();
            w2 = in.readInt();
            w3 = in.readInt();
            System.out.println("westelijke breedtegraad: " + w1 + ", " + w2 + ", " + w3);
            e1 = in.readInt();
            e2 = in.readInt();
            e3 = in.readInt();
            System.out.println("oostelijke breedtegraad: " + e1 + ", " + e2 + ", " + e3);
            color = in.readString();
            System.out.println("De kleur van de kaart: " + color);
            edition = in.readString();
            System.out.println("Editie: " + edition);
            scale = in.readString();
            System.out.println("Schaal: " + scale);
            title = in.readLine();
            System.out.println("Kaart: " + title);
            System.out.println("");
            Pos north = new Pos(n1,n2,3);
            Pos south = new Pos(s1,s2,s3);
            Pos west = new Pos(w1,w2,w3);
            Pos east = new Pos(e1,e2,e3);
            Chart chart = new Chart(north, south, west, east, color, scale, edition, title);
        }
        catch(NoSuchElementException eNSEE){
                System.out.println("No such element exception");
        }
    }
    in.close();

我真的希望我能得到一些帮助，因为我无可救药地陷入困境。 可能对Pos所做的更改我也必须更改为Chart，因为构建是相同的

先谢谢您的帮助。

Answer 1

在这里，在构造函数中它正在调用自身，所以有一个StackOverflowException

public Pos(int d, int m, int t){
     Pos pos = new Pos(d,m,t);<=here!
}

Answer 2

您的密码

public Pos(int d, int m, int t){
  Pos pos = new Pos(d,m,t);
}

运行此代码时，它将递归调用Pos构造函数本身，因此将其堆叠并调用内部Pos（），然后StackoverFlowException不会太奇怪。

你的课应该是

class Pos {
    int d;
    int m;
    int t;

    public Pos(int d, int m, int t) {
       this.d = d;
       this.m = m;
       this.t = t;
    }
}
