Overriding parameterized method of Vector

Question

I'm doing a simple "ringbuffer" implementation of a Vector and I want to override the add(E o) method of Vector but I get the error: "The method add(E) of type RingBufferVector<E> has the same erasure as add(E) of type Vector<E> but does not override it". Why doesn't it override it? How do I make it so?
Here's the code...
public class RingBufferVector<E> extends Vector {
     private static final long serialVersionUID = 1L;
     * Using mode append will cause the vector to remove the first element and then append the new entry at the end of the vector, when the buffer limit has been reached.
     public static final int APPEND_MODE = 0;
     * Using mode loop will cause the vector to overwrite elements when the buffer limit is reached. I.e. the first time an element is added when the limit is reached, the new element will be inserted at position 0, overwriting the previous value.
     public static final int LOOP_MODE = 0;
     private int mode;
     private int maxSize;
     public RingBufferVector(int mode, int maxSize) {
          this.mode = mode;
          this.maxSize = maxSize;
     public boolean add(E o) {
          return false;
}

... How do I make it so?By telling the compiler your Vector also holds type E:
public class RingBufferVector<E> extends Vector<E> {
}Good luck.
