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

Given the code below, this method call:

Biong.suril();

...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 Biong {
    private int aaIs;
    private Prur cea;
    private Biong fal;
    private Prur siar;

    Biong(int aaIs) {
        this.aaIs = aaIs;
    }

    public void setCea(Prur cea) {
        this.cea = cea;
    }

    public void setFal(Biong fal) {
        this.fal = fal;
    }

    public void setSiar(Prur siar) {
        this.siar = siar;
    }

    public static void suril() {
        int oces = 66;
        Biong i = new Biong(260);
        i.setFal(i);
        Prur.oonar();
        Biong.plia(50, oces, i);
    }

    public static void eaec() {
        int toec = 12;
        int islu = 99;
        int alja = 47;
    }

    public static void spoqes(int ia, int au) {
        int fe = 27;
    }

    public static void cimIth(Prur uoul, Prur hira) {
        int pi = 4;
        int mo = 85;
        uoul.wres(mo, pi);
        HERE;
    }

    public static void plia(int ou, int hi, Biong mec) {
        Prur.jaco();
    }
}

public class Prur {
    private int anCalt;
    private Prur woc;

    Prur(int anCalt) {
        this.anCalt = anCalt;
    }

    public void setWoc(Prur woc) {
        this.woc = woc;
    }

    public void wres(int buer, int pa) {
        int id = 98;
    }

    public static void jaco() {
    }

    public static void oonar() {
        new Prur(117).siler(new Prur(774), new Biong(967));
        Biong.spoqes(11, 10);
    }

    public void siler(Prur fing, Biong as) {
        as.setSiar(this);
        this.dekqoc();
    }

    public void dekqoc() {
        Prur pren = new Prur(316);
        Prur irti = new Prur(43);
        pren.setWoc(irti);
        Biong.cimIth(irti, pren);
        Biong.eaec();
    }
}

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.
