Write a program to read book information (bookid, bookname, bookprice, bookqty) in file “book.dat”. Write a menu driven program to perform the following operations using Random access file: i. Search for a specific book by name. ii. Display all book and total cost

import java . io .*; import java . util .*; class Book { String name , id ; int qty ; double price , total ; Book ( String i , String n , String p , String q ) { name = n ; id = i ; qty = Integer . parseInt ( q ); price = Double . parseDouble ( p ); total = qty * price ; } public String toString () { System . out . println ( "name\t id\t qty\t price\t total" ); String s = name + "\t" + id + "\t" + qty + "\t" + price + "\t" + total ; ...

Define a class MyDate (day, month, year) with methods to accept and display a MyDate object. Accept date as dd, mm, yyyy. Throw user defined exception “InvalidDateException” if the date is invalid. Examples of invalid dates : 03 15 2019, 31 6 2000, 29 2 2021

import java . io .*; import java . util .*; class InvalidDateException extends Exception { InvalidDateException () { System . out . println ( "Invalid Date" ); } } class MyDate { int day , mon , yr ; void accept ( int d , int m , int y ) { day = d ; mon = m ; yr = y ; } void display () { System . out . println ( "Date is valid : " + day + "/" + mon + "/" + yr ); } } class Date { public static void main ( String args []) throws Exception { Scanner sc = new Sca...

Write a Java program to design a screen using Awt that will take a user name and password. If the user name and password are not same, raise an Exception with appropriate message. User can have 3 login chances only. Use clear button to clear the TextFields.

import java . awt .*; import java . awt . event .*; import javax . swing .*; class InvalidPasswordException extends Exception { InvalidPasswordException () { System . out . println ( "Username and password is not same" ); } } public class Password extends Frame implements ActionListener { Label uname , upass ; TextField nametext ; TextField passtext , msg ; Button login , Clear ; Panel p ; int attempt = 0 ; char c = '*' ; public void login () { p = new Panel (); uname = new Label ( "Username : " , Label . CENTER ); upass = n...
