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


Given the code below, this method call:

Pedot.pepced();

...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:

The code:

public class Pedot {
    private int dango;
    private Rar li;

    Pedot(int dango) {
        this.dango = dango;
    }

    public void setLi(Rar li) {
        this.li = li;
    }

    public void momred(Pedot rade, Rar da) {
    }

    public static void pepced() {
        new Rar(901).voem(new Pedot(79), new Rar(887));
    }
}
public class Rar {
    private int erlar;

    Rar(int erlar) {
        this.erlar = erlar;
    }

    public void voem(Pedot palo, Rar ba) {
        palo.momred(palo, this);
        palo.setLi(this);
        HERE;
    }
}
