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

Given the code below, this method call:

Gacir.uhoong();

...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 Gacir {
    private int cipri;
    private Cung os;
    private Cung iost;

    Gacir(int cipri) {
        this.cipri = cipri;
    }

    public void setOs(Cung os) {
        this.os = os;
    }

    public void setIost(Cung iost) {
        this.iost = iost;
    }

    public void fepre(int reng, int id) {
    }

    public static void duang() {
    }

    public static void uhoong() {
        int maus = 50;
        new Cung(123).dosres(new Cung(685), maus, new Cung(586));
        Cung.icam();
        Cung.iatist(maus, maus);
    }
}

public class Cung {
    private int okSohe;
    private Cung tro;
    private Gacir kosu;

    Cung(int okSohe) {
        this.okSohe = okSohe;
    }

    public void setTro(Cung tro) {
        this.tro = tro;
    }

    public void setKosu(Gacir kosu) {
        this.kosu = kosu;
    }

    public void blora() {
        int de = 72;
        Gacir slie = new Gacir(754);
        Gacir au = new Gacir(211);
        int eid = 88;
        au.setIost(this);
        HERE;
        slie.fepre(43, de);
    }

    public static void paiMevia(Cung zeng, Cung rasm, Gacir pimi) {
    }

    public static void icam() {
        int ongi = 63;
        new Cung(889).sarcen(new Cung(134));
        Gacir.duang();
    }

    public void cewRaru(Cung bres) {
        Gacir la = new Gacir(27);
        Cung trea = new Cung(913);
        this.setKosu(la);
        trea.blora();
    }

    public void dosres(Cung ece, int glan, Cung ri) {
        Cung.paiMevia(this, ece, new Gacir(36));
    }

    public static void piad() {
    }

    public void sarcen(Cung ouva) {
        int opla = 9;
        ouva.setTro(this);
        ouva.cewRaru(this);
    }

    public static void iatist(int ero, int prid) {
        int oor = 21;
        int reso = 45;
        int suc = 42;
        Cung.piad();
    }
}

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.)
