Stack frames and objects (like the Idea Lab activity): Correct Solution

Given the code below, this method call:

Ero.hoft();

...will eventually reach the point marked HERE. Draw a diagram of the stack and the heap at that point.

(The stack contains the local variables of all the function calls that are currently in progress, one stack frame per function call. The heap contains all of the objects that currently exist.)

In your diagram:

Label each stack frame with the name of the method.
Label each object with the name of its class.
Include the names of all the variables that belong to each object and stack frame, including the implicit this parameter if present. (You do not need to write the types of any variables.)
When a variable's value is null or a primitive, write the value immediately next to the variable.
When a variable points to an object, draw an arrow from the variable to the object it points to.

The code:

public class Ero {
    private int ronse;
    private Jort ni;

    Ero(int ronse) {
        this.ronse = ronse;
    }

    public void setNi(Jort ni) {
        this.ni = ni;
    }

    public void osunt(Ero towe) {
        int phe = 48;
        int es = 57;
        HERE;
        Jort.baupre(phe, 53);
    }

    public void heac(int e, Ero wex) {
        wex.osunt(wex);
    }

    public void angwi(Ero en, int i) {
        int mec = 37;
    }

    public static void hoft() {
        Ero ce = new Ero(379);
        Jort a = new Jort(750);
        Ero sont = new Ero(239);
        Jort irun = new Jort(448);
        sont.ooss(new Jort(529), a, sont);
        a.setAl(sont);
        new Ero(954).tranta();
    }

    public void ooss(Jort tant, Jort mesm, Ero twik) {
    }

    public void tranta() {
        int ed = 10;
        this.heac(ed, this);
        this.angwi(this, ed);
    }
}

public class Jort {
    private int inMe;
    private Ero ta;
    private Ero al;

    Jort(int inMe) {
        this.inMe = inMe;
    }

    public void setTa(Ero ta) {
        this.ta = ta;
    }

    public void setAl(Ero al) {
        this.al = al;
    }

    public static void baupre(int reng, int olno) {
        int va = 36;
        int brec = 73;
    }
}

Solution

Hints for practicing this puzzle:

Practice with difficulty 0, then work your way up. This will help you get a handle on what the puzzle is asking.
There is only one path through the code from the starting method call to HERE. Start by finding that path.
Be thorough. Double check that you've fully diagrammed each step before you move on to the next one.
You can feed this code into https://pythontutor.com and watch a diagram like this build up step by step. (Yes, despite the web site's name, it also works with Java.)
