java - How do I implement generics <E> in a linked List? -

i have been trying create linked list uses generics return data type of user's choosing. problem method public e get(int sub) not recognizing return cursor.contents type e generic.

public e get(int sub) {     node cursor = head; //start @ beginning of linked list.       (int c = 1; c <= sub; c++)     {         cursor = cursor.next; //move forward one.      }      return cursor.contents;//return element cursor landed on.  }    public class node <e> {         public e contents;      @suppresswarnings("rawtypes")     public node next = null; //points next node     //a method has no return type , has same name class     public node(e element)     {         this.contents = element;      } } 

as have shown above contents parameter declared type e in node, method not recognize cursor.contents proper return type.

the system recomments either change return type object, not option. or change contents type e has been done, still gives me compilation error.

that's because need change to:

public e get(int sub) {     node<e> cursor = head; //you forgot generics here      (int c = 1; c <= sub; c++)     {         cursor = cursor.next;      }      return cursor.contents; }    public class node <e> {     public e contents;      public node<e> next = null; //you suppressed raw type here      public node(e element)     {         this.contents = element;      } }
