New to Java

I have filtered though an hour of forum posts and find that my problem seems different to everyone elses. I am trying to implement a linked queue through jroff and I keep having the error come up.

Also I have an incompatible type error that comes up too. Does anyone know how to convert a string to an object?

linkedqueue.java

import java.util.NoSuchElementException;

class linkedqueue <Object> {

   private class node{
      Object value = null;
      node link = null;
   }

   private node front = null;
   private node rear = null;
/*
   public boolean empty (){
      return front == null;
   }
*/
   // ------- insert new obejct into rear of the list
   public void insert (String obj) {
     // stub if list is null return null
      node previous = null;
      // Find the end of the list.
      for( node itor = this.front; itor != null; itor = itor.link ){
         previous = itor;
      };
      // Make a new node.
      node newnode = new node();
      newnode.value = obj; <---- incompatible error here
      newnode.link = null;
      // Insert it at the end of the list or at the head, if empty.
      if( previous == null ) this.front = newnode;
                        else previous.link = newnode;
   }

  public String remove (){
    Object obj = front.value;
    String temp = obj.toString();
    front = front.link;
    return temp;
 }

}

jroff.java

import java.io.*;
import java.util.Scanner;
import static java.lang.System.*;

public class jroff{
   final static String STDIN_NAME = "-";
public
   static void scanfile (String filename, Scanner infile) {
      err.printf ("STUB: filename = %s%n", filename);
      for (int linenr = 1; infile.hasNextLine(); ++linenr) {
         String line = infile.nextLine(); // get the line
         if(line.length()==0){
           err.printf (".sp 1%n");
           
         }
         else if(line.length()>=1){
        char c = line.charAt( 0 );
         if(c == '.'){
           err.printf ("This line begins with a period.");
         }
         }
         err.printf ("STUB: %s: %4d: \"%s\"%n", filename, linenr, line);
         String[] words = line.split ("\\s+"); // split the line by spaces
         for (String word: words) {

           linkedqueue.insert(word); <---static context error here
            err.printf ("print STUB: word = \"%s\"%n", word);
         }
      }
   }

   public static void main (String[] args) {
           linkedqueue wordqueue = new linkedqueue ();
      if (args.length == 0) {
         scanfile (STDIN_NAME, new Scanner (in));
      }else {
         for (String filename : args) {
            if (filename.equals (STDIN_NAME)) {
               scanfile (STDIN_NAME, new Scanner (in));
            }else {
               try {
                  Scanner scan = new Scanner (new File (filename));
                  scanfile (filename, scan);
                  scan.close();
               }catch (IOException error) {
                  auxlib.warn (error.getMessage());
               }
            }
         }
      }
   }

}

I am trying to add the words printed to the rear of the linked queue.

Any and all help will be greatly appraciated.
