html - take 5 numbers one at a time from a form in a jsp page and calculate the average with a java class? -

I have a form, I want these input numbers at the same time.

I pass an object and getParameter () values,

   & Lt; Input type = "hidden" name = "hidden control" value = "" /> & Lt;% string input = request.getParameter ("input"); String hidden quarters = request.GetPamator ("hidden quarter"); Control. Main program main = new control Main program (input, hidden control); & Gt%; & Lt; Input type = "submit" value = "submit number" /> & Lt;% out.println (main .getResult ()); & Gt%; & Lt; / Form & gt;   
 In the Java class, the constructor valves the value and sets the variable  
  public keyprogram (string input, string hidden control) {try {number = Integer.parseInt (input); Counter = integer Parseint (hidden control); } Hold (NumberFormatException e) {}} Public int getResult () {Return Number; }   
 How can I add numbers to each number presented?  
 The problem every time the constructor is called, it sets the number to the number submitted to the variable.  
 Something like this  
  number + = number;   
 Explicit work (variables due to its reset)  
 ive Search & amp; Can anyone help?   
 
 
 If you are not concerned about multi-threaded access, you can only select  numbers < / Code>  static   
 variable will be bound to  control.MainProgram   class  instead of an example.  
 Then you ... try  
  {number + = integer.PERSIN (input); Also declare as   
 ... then  getResult   still  ...  
 ... Then open it by  & lt;% out.println (control.MainProgram.getResult ()); % & Gt;   
 Note that this does not give you an average, because your title means - it gives you the amount.  
 But it is simple to apply the average in your body of  stable int getResult  method.
