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

Given the code below, this method call:

Weda.licfu();

...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 Weda {
    private int risma;
    private Weda losi;
    private Ert psas;

    Weda(int risma) {
        this.risma = risma;
    }

    public void setLosi(Weda losi) {
        this.losi = losi;
    }

    public void setPsas(Ert psas) {
        this.psas = psas;
    }

    public static void shemil(int ae, int ge, int co) {
        int epe = 29;
    }

    public void tiod(Weda el) {
        int ent = 99;
    }

    public static void asiArdias() {
    }

    public static void ephJulin(int diad) {
        int cas = 49;
        int uac = 21;
        Weda.shemil(uac, cas, diad);
        Ert.psaGetart(uac, diad, cas);
    }

    public static void licfu() {
        Ert bemi = new Ert(654);
        Weda ar = new Weda(941);
        Ert hec = new Ert(351);
        Ert eie = new Ert(454);
        Weda al = new Weda(955);
        al.setPsas(bemi);
        new Weda(217).socsio(bemi, hec);
        Ert.thim();
    }

    public void socsio(Ert iw, Ert thie) {
        int mo = 36;
        this.tiod(this);
        thie.setPism(iw);
        Ert.scesre();
        thie.phicbe();
    }
}

public class Ert {
    private int ghiss;
    private Ert tarm;
    private Ert pism;

    Ert(int ghiss) {
        this.ghiss = ghiss;
    }

    public void setTarm(Ert tarm) {
        this.tarm = tarm;
    }

    public void setPism(Ert pism) {
        this.pism = pism;
    }

    public void phicbe() {
        int thil = 39;
    }

    public static void scesre() {
        int nir = 59;
        Weda.ephJulin(nir);
    }

    public static void thim() {
        int ko = 41;
        int fua = 29;
        Weda.asiArdias();
    }

    public static void psaGetart(int uren, int re, int iint) {
        int em = 84;
        int pe = 50;
        HERE;
    }
}

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.)
