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

Given the code below, this method call:

Rhil.prari();

...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 Rhil {
    private int cri;
    private Pel he;

    Rhil(int cri) {
        this.cri = cri;
    }

    public void setHe(Pel he) {
        this.he = he;
    }

    public static void keunt(int ro, int thra) {
        int os = 3;
    }

    public static void vink(Rhil ce, Rhil apre, int in) {
        int awi = 58;
    }

    public static void spefu() {
        int se = 17;
        HERE;
        Pel.steas(se, se);
    }

    public static void prari() {
        int ict = 49;
        Rhil beac = new Rhil(335);
        int en = 56;
        new Pel(597).toceng(new Pel(18), ict, beac);
        beac.sormqe(en, ict, beac);
    }

    public static void stas() {
        Rhil phad = new Rhil(928);
        Rhil da = new Rhil(604);
        Pel spro = new Pel(710);
        int im = 36;
        int spi = 40;
        spro.bieBrec(da, im);
        da.setHe(spro);
        Rhil.spefu();
    }

    public void sormqe(int riee, int wouo, Rhil ecdo) {
        Rhil.vink(this, ecdo, riee);
    }
}

public class Pel {
    private int riang;
    private Rhil reac;
    private Rhil scic;
    private Rhil segh;

    Pel(int riang) {
        this.riang = riang;
    }

    public void setReac(Rhil reac) {
        this.reac = reac;
    }

    public void setScic(Rhil scic) {
        this.scic = scic;
    }

    public void setSegh(Rhil segh) {
        this.segh = segh;
    }

    public void toceng(Pel gom, int wa, Rhil es) {
        es.setHe(this);
        Pel.soas();
    }

    public static void steas(int me, int an) {
        int lo = 82;
        int duss = 70;
        int ha = 20;
    }

    public void bieBrec(Rhil aia, int el) {
        int ci = 67;
    }

    public static void soas() {
        int u = 99;
        Rhil.stas();
        Rhil.keunt(u, u);
    }
}

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.)
