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

Given the code below, this method call:

Oran.moovil();

...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 Oran {
    private int danen;
    private Oran muro;
    private Cacse opac;

    Oran(int danen) {
        this.danen = danen;
    }

    public void setMuro(Oran muro) {
        this.muro = muro;
    }

    public void setOpac(Cacse opac) {
        this.opac = opac;
    }

    public static void moovil() {
        int ea = 88;
        int drin = 86;
        Oran anae = new Oran(849);
        Oran.acriss(ea);
    }

    public void tinwus(Oran ooss) {
        int mier = 96;
        Cacse.pabli();
        ooss.setMuro(this);
        HERE;
    }

    public static void acriss(int ec) {
        Cacse am = new Cacse(444);
        am.breett(new Oran(757));
        am.eumNoston(new Cacse(227), ec);
    }
}

public class Cacse {
    private int ded;
    private Oran rerd;

    Cacse(int ded) {
        this.ded = ded;
    }

    public void setRerd(Oran rerd) {
        this.rerd = rerd;
    }

    public static void aedBir(Cacse smar, int ehen) {
    }

    public void breett(Oran craa) {
        int lugh = 81;
        Oran twec = new Oran(45);
        twec.setOpac(this);
        twec.tinwus(craa);
        Cacse.aedBir(this, lugh);
    }

    public static void pabli() {
    }

    public void eumNoston(Cacse da, int vec) {
        int spel = 60;
    }
}

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.)
