In our program it may be that we may have multiples
values for a single parameter like in checkboxes. We are going to make one
program over it.
To make such a servlet which we have made one html form from where the values will be passed to the controller. In this program we have used the checkbox which will have the same name but with different values. We have one more button submit, on pressing this button the request will be forwarded.
Now in the servlet that is working like a controller will retrieve the values we have entered in the html form by the method getParameterValues() which returns the array of String. At last to retrieve all the values from the array use the for loop. The output will be displayed to you by the PrintWriter object.
