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

Given the code below, this method call:

Pralu.sarm();

...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 Pralu {
    private int celas;
    private Pralu abis;
    private Pralu da;

    Pralu(int celas) {
        this.celas = celas;
    }

    public void setAbis(Pralu abis) {
        this.abis = abis;
    }

    public void setDa(Pralu da) {
        this.da = da;
    }

    public static void melsen(int co, Truol qes) {
    }

    public static void casphi() {
        Pralu drio = new Pralu(566);
        Truol stru = new Truol(510);
        stru.selis();
    }

    public static void sarm() {
        Pralu.casphi();
        new Truol(452).miseas();
    }

    public static void oelgru(int leti, int ad) {
        int io = 70;
        int etic = 98;
        int hiad = 68;
    }

    public void psoo() {
        int dolo = 30;
        int dic = 34;
        int so = 67;
        int de = 8;
        this.setAbis(this);
        Truol.lioLucse();
    }

    public void miba() {
        Pralu to = new Pralu(127);
        Pralu ineo = new Pralu(355);
        int heda = 20;
        int suc = 49;
        to.setDa(this);
        this.psoo();
        Truol.ledxin(this, suc, to);
    }
}

public class Truol {
    private int craci;
    private Pralu vio;
    private Truol amo;

    Truol(int craci) {
        this.craci = craci;
    }

    public void setVio(Pralu vio) {
        this.vio = vio;
    }

    public void setAmo(Truol amo) {
        this.amo = amo;
    }

    public static void lioLucse() {
        Pralu.oelgru(95, 73);
        HERE;
    }

    public static void ledxin(Pralu scok, int esm, Pralu qer) {
        int seho = 46;
        int sti = 0;
    }

    public void selis() {
        int leua = 48;
    }

    public void miseas() {
        Truol as = new Truol(496);
        Truol esso = new Truol(68);
        this.setAmo(esso);
        new Pralu(531).miba();
        Pralu.melsen(96, this);
    }
}

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.)
