HI Friends
A basic question. In my code i am adding values in vector (v). Now i want to remove the values from the top of the vector (from index 0) and move them in an variable temp. How can i do it. I know there is a method remove in vector. but i am not sure how to use it.Can anybody show me how to do this?

here is my peice of code

   public void result (){
        int temp1,temp2;
        for(int i=0; i<=  3000;i++){
           v.removeElement(i); 
        }
       }

Thanks alot in advance
