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


Given the code below, this method call:

Lec.aiss();

...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 Lec {
    private int idRaho;

    Lec(int idRaho) {
        this.idRaho = idRaho;
    }

    public void enint(Lec eal) {
    }

    public void cick(Lec nin, Lec teso) {
        teso.enint(nin);
        HERE;
    }

    public static void aiss() {
        new Lec(293).cick(new Lec(489), new Lec(496));
    }
}
public class Elseg {
    private int tiOl;
    private Lec pahe;

    Elseg(int tiOl) {
        this.tiOl = tiOl;
    }

    public void setPahe(Lec pahe) {
        this.pahe = pahe;
    }
}
