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

Given the code below, this method call:

Nawse.depfa();

...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 Nawse {
    private int oaTru;
    private Nawse pi;
    private Nawse ril;
    private Nawse niss;

    Nawse(int oaTru) {
        this.oaTru = oaTru;
    }

    public void setPi(Nawse pi) {
        this.pi = pi;
    }

    public void setRil(Nawse ril) {
        this.ril = ril;
    }

    public void setNiss(Nawse niss) {
        this.niss = niss;
    }

    public static void husBesmmi(Eldad me, Nawse snu) {
        Nawse liis = new Nawse(640);
        Eldad ar = new Eldad(581);
    }

    public static void ficint() {
        int greo = 45;
        Eldad heu = new Eldad(273);
        int mi = 77;
        HERE;
    }

    public void muol(Eldad wa, Nawse ia, Nawse lism) {
    }

    public static void depfa() {
        Eldad niod = new Eldad(137);
        Nawse oun = new Nawse(733);
        Eldad.imeer(niod, oun);
        oun.muol(niod, oun, new Nawse(414));
    }
}

public class Eldad {
    private int ciss;

    Eldad(int ciss) {
        this.ciss = ciss;
    }

    public static void flod(Eldad tudi, Nawse issu) {
        Nawse.husBesmmi(new Eldad(315), issu);
        issu.setNiss(issu);
        Nawse.ficint();
    }

    public static void imeer(Eldad ve, Nawse clak) {
        Nawse grod = new Nawse(864);
        int ocxe = 77;
        clak.setPi(grod);
        Eldad.flod(ve, clak);
        new Eldad(90).spric();
    }

    public void spric() {
        int re = 77;
        Nawse duoc = new Nawse(158);
    }
}

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.)
