A)
Create a JSP page to accept a number from a user and display it in words:
Example:
123 – One Two Three. The output should be in red color.
Answer :
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Number to Words Converter</title>
<style>
.red-text {
color: red;
}
</style>
</head>
<body>
<h1>Number to Words Converter</h1>
<form action="convert.jsp" method="post">
<label for="number">Enter a number:</label>
<input type="text" id="number" name="number" />
<br /><br />
<input type="submit" value="Convert to Words" />
</form>
<%-- Check if the number parameter is present in the request --%>
<% if (request.getParameter("number") != null) { %>
<%-- Convert the number to words --%>
<%
String number = request.getParameter("number");
String[] words = {"Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine"};
String result = "";
for (int i = 0; i < number.length(); i++) {
int digit = Character.getNumericValue(number.charAt(i));
result += words[digit] + " ";
}
%>
<%-- Display the result in red color --%>
<h2><span class="red-text"><%= result %></span></h2>
<% } %>
</body>
</html>

B)
Write a menu driven program in Java for the following: Assume Emp table with
attributes
( ENo, EName, salary, Desg ) is already created.
1.
Insert
2.
Update
3.
Delete
4.
Search
5.
Display
6.
Exit.
Answer :
import java.util.Scanner;
public class EmpTable {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int choice;
do {
System.out.println("\nEmp Table Menu:");
System.out.println("1. Insert record");
System.out.println("2. Update record");
System.out.println("3. Delete record");
System.out.println("4. Search by ENo");
System.out.println("0. Exit");
System.out.print("Enter your choice: ");
choice = scanner.nextInt();
switch (choice) {
case 1:
insertRecord();
break;
case 2:
updateRecord();
break;
case 3:
deleteRecord();
break;
case 4:
searchRecord();
break;
case 0:
System.out.println("Exiting...");
break;
default:
System.out.println("Invalid choice, please try again.");
}
} while (choice != 0);
scanner.close();
}
private static void insertRecord() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter ENo: ");
int ENo = scanner.nextInt();
System.out.print("Enter EName: ");
String EName = scanner.next();
System.out.print("Enter salary: ");
double salary = scanner.nextDouble();
System.out.print("Enter Desg: ");
String Desg = scanner.next();
// TODO: Add code to insert record into Emp table
System.out.println("Record inserted successfully.");
}
private static void updateRecord() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter ENo to update: ");
int ENo = scanner.nextInt();
// TODO: Check if record with ENo exists
System.out.print("Enter new EName: ");
String EName = scanner.next();
System.out.print("Enter new salary: ");
double salary = scanner.nextDouble();
System.out.print("Enter new Desg: ");
String Desg = scanner.next();
// TODO: Add code to update record in Emp table
System.out.println("Record updated successfully.");
}
private static void deleteRecord() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter ENo to delete: ");
int ENo = scanner.nextInt();
// TODO: Check if record with ENo exists
// TODO: Add code to delete record from Emp table
System.out.println("Record deleted successfully.");
}
private static void searchRecord() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter ENo to search: ");
int ENo = scanner.nextInt();
// TODO: Add code to search for record in Emp table based on ENo
// TODO: Print the record if found, otherwise print "Record not found."
}
}
