Please, I need help debugging compiler error

Question

I am new to Java and I do not know why the compiler (Forte for Java) has the following error. Seems like the compiler does not accept NEW for adding new entries to a Vector table.
ERROR:
UAL_LearningPrograms/MyVector.java [12:1] non-static variable this cannot be referenced from a static context
mv.vtable.addNode(new Node(names[n]));
JAVA CODE:
package UAL_LearningPrograms;
import java.util.*;
class MyVector {
private Vtable vtable;
public static void main(String[] args){
MyVector mv = new MyVector();
String names[] = {"one","two","three","four","five"};
for (int n;n<names.length;n++)
mv.vtable.addNode(new Node(names[n]));
public MyVector(){  // Class constructor
System.out.println("MyVector_C");
vtable = new Vtable();
public class Node {
private String name;
public Node(String s){name=s;}
public class Vtable extends Vector {
private Vector v;
public Vtable(){v=new Vector();}
public void addNode(Node n){v.add(n);}

Answer 1

You were trying to reference a non-static variable
from a static context... not allowed.
Simple modification allows that code to work.
If this helps... give me the dollars... thanks!
import java.util.*;
class MyVector
     private Vtable vtable;
     public static void main(String[] args)
          String names[] = {"one","two","three","four","five"};
          MyVector mv = new MyVector();
          mv.vtable.addNodes(names);
     } // main
     public MyVector()
          System.out.println("MyVector_C");
          vtable = new Vtable();
     } // MyVector
     public class Node
          private String name;
          public Node(String s)
               name = s;
          } // Node
     } // Node
     public class Vtable
          extends Vector
          private Vector v;
          public Vtable()
               v=new Vector();
          } // Vtabl3
          public void addNodes(String n[])
               for (int i = 0; i < n.length; ++i)
                    v.add(new Node(n));
          } // addNode
          public void addNode(Node n)
               v.add(n);
          } // addNode
     } // Vtable
} // MyVector
