Java stackOverFlow error Objects aren't coded the right way

Question

I'm working on a project for shipping maps. I've created an object called Chart and an object called Pos for the position. What i can't get to work is that when i read te charts from a text file to create the object Pos correctly because that is where it fails.

Now here is the Pos Class

 private Pos Pos;

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

Now here is the Chart class

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);
}

Now here is where i want the code to create charts. I've made a lot of small steps to make sure the output is correct:

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();

I'm really hoping i could get some help because i'm hopelessly stuck. Probaly the changes made to Pos i also have to alter to Chart because the build up is the same

Thanks in advance for the help.

edit: This is the text file that i am processing

Answer 1

Your code

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

When this code run, it recursively call Pos contructor itself, so it will be stacked and call inner Pos() then StackoverFlowException would not be so strange.

Your class should be

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;
    }
}

Answer 2

Here, in your constructor it is calling itself, so there is a StackOverflowException

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