Both of these are totally different things with nothing
common except the word "java". Javascript is a scripting
language that is interpreted by ur internet
browser.Javascript has nothing to do with the java
language, although it contains java in its name. As far as
its use is concerned, it is used mostly to validate the
user input on web forms. Also it is gr8ly used to change
the appearance of ur web page dynamically.
On the other hand, jsp is a part of java language and it
stands for java server pages. Server pages are the pages
that dynamically change their content according to the user
input(e.g when u login to hotmail or yahoo, it shows u ur
account after loging in). So jsp supports these dynamic
features and interaction with the databases.

jsp is server side language so it is run on the java
enabled server or any server like apatchi tomacat.
when u run the jsp page then every time page will refreshed
by the server
whre as Java scrip is a language which is used to perform
the validating task of the project it won't be refreshed by
the server rather than browser.

Answer / ankur pandya
When you run JSP, the web page has to call the server so you
will get a refresh on your page.
when you run Javascript the code runs on your computer via
the browswer so there is no refresh to your page.
Java and Javascript are completely separate languages and
have nothing to do with each other. A JSP, Java Servlet Page
is of the Java language

The following program reads data (details of students) from a file named students.txt and converts it into e-mail addresses. The results are written to a file named studentemail.txt. students.txt consists of a number of lines, each containing the data of a student in colon delimited format: Last Name:First Name:Student Number Each input record is converted to an e-mail address and written to studentemail.txt in the following format: the first character of the last name + the first character of the first name + the last four digits of the student number + “@myunisa.ac.za” import java.io.*; public class EmailConverter { public static void main(String[] args) throws IOException { BufferedReader input = new BufferedReader(new FileReader ("students.txt")); PrintWriter output = new PrintWriter(new FileWriter ("studentemail.txt")); String line = input.readLine(); while (line != null) { // Extract the information for each student String[] items = line.split(":"); // Generate the email address String email = "" + items[0].charAt(0) + items[1].charAt(0) + items[2].substring(4,8) + "@myunisa.ac.za"; email = email.toLowerCase(); // Output output.println(email); line = input.readLine(); } input.close(); output.close(); } } Rewrite the class so that it handles possible errors that may occur. In particular, it should do the following: • It should catch at least three appropriate exceptions that might occur, and display suitable messages. • At this stage, the program will not run correctly if there is an empty line in the input file. Change the program so that if an empty line is encountered, an exception is thrown and the empty line is ignored. This exception should be handled with the display of a suitable error message. • Before the e-mail address is added to the output file, check if the student number has 8 digits. If not, throw an InvalidFormatException (which the program should not handle itself)
