Suppose you have the following code.
Which of the images best represents the state of the references
right before the end of the main method,
assuming garbage collection hasn’t run?
public class Link {
private String name;
private Link next;
public Link(String name, Link next) {
this.name = name;
this.next = next;
}
public void setNext(Link next) {
this.next = next;
}
public Link getNext() {
return next;
}
public static void main(String... args) {
Link link1 = new Link("x", null);
Link link2 = new Link("y", link1);
Link link3 = new Link("z", link2);
link2.setNext(link3);
link3.setNext(link2);
link1 = null;
link3 = null;
}
}
