If I have this class and I want to initialize a new field of type Element
,
how can I do that?
public class MyLinkedList{
protected Element head, tail;
public final class Element{
Object data;
int priority;
Element next;
Element(Object obj, int priorit, Element element){
data = obj;
priority = priorit;
next = element;
}
}
}
when I tried to do this, it gave me an error.
public class PriorityTest{
public static void main(String[]args){
MyLinkedList.Element e1 = new MyLinkedList.Element("any", 4, null);
}
}
Try this
MyLinkedList.Element e1 = new MyLinkedList().new Element("any", 4, null);
your inner class is not static
so you need to create an object of outer class first.
