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

Given the code below, this method call:

Scu.rolCeng();

...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 Scu {
    private int orEr;
    private Injuc stua;
    private Scu sqi;
    private Scu da;
    private Scu nac;

    Scu(int orEr) {
        this.orEr = orEr;
    }

    public void setStua(Injuc stua) {
        this.stua = stua;
    }

    public void setSqi(Scu sqi) {
        this.sqi = sqi;
    }

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

    public void setNac(Scu nac) {
        this.nac = nac;
    }

    public static void rolCeng() {
        Scu o = new Scu(408);
        o.setNac(o);
        Injuc.serxes();
    }

    public static void molorm(Injuc e) {
        Injuc us = new Injuc(445);
        Scu onpu = new Scu(324);
    }

    public void scoer(Injuc iss, int pism) {
    }

    public void semcil(Injuc ol, Injuc oss) {
        Scu su = new Scu(429);
        Scu.molorm(ol);
        this.setSqi(su);
        new Injuc(152).hasmi();
        ol.wuelo(su, oss);
    }
}

public class Injuc {
    private int sont;

    Injuc(int sont) {
        this.sont = sont;
    }

    public void hasmi() {
        int in = 75;
        HERE;
    }

    public void wuelo(Scu va, Injuc ral) {
    }

    public static void serxes() {
        Injuc en = new Injuc(473);
        int hos = 53;
        int ac = 58;
        new Scu(878).scoer(en, hos);
        new Injuc(944).sepe(hos, en, ac);
        en.wereel(31, ac);
    }

    public void wereel(int mo, int arto) {
        int pel = 8;
        int je = 49;
    }

    public void sepe(int reiw, Injuc a, int anen) {
        new Scu(278).semcil(a, 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.
