In this HW, we are validating the user name and password entered by the user. If the user name and password are correct, it will forward the request to the WelcomeServlet, otherwise will show an error message: “Sorry username or password are not correct". In this HW, you have created following files: index.html: for getting input from the user. Login.java: a servlet class for processing the response. If the user name equals to your name and the password is equals to your student ID, it will forward the request to the welcome servlet. WelcomeServlet.java: a servlet class for displaying the welcome message (Welcome [user name]). web.xml: a deployment descriptor file that contains the information about the servlet.

First: write a function named get_parts(string) that will that will receive as its arguments a string with the client data for one client, for example “Lin ,Nenya,00548”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and newlines from the end of the parts.You’ll need to use some of the string methods that we covered in this lessonYou can test your function by with a main() that is just the function call with the argument typed…Focus on string operations and methodsYou work for a small company that keeps the following information about its clients: • first name• last name • a 5-digit user code assigned by your company.The information is stored in a file clients.txt with the information for each client on one line(last name first), with commas between the parts.
