Yes, by using this() syntax. E.g.

public Pet(int id) {
this.id = id; // “this” means this object
}
public Pet (int id, String type) {
this(id); // calls constructor public Pet(int id)
this.type = type; // ”this” means this object
}

I want to re-reach and use an object once it has been garbage collected. How it's possible?
