             Scanner sc=new Scanner(f);
             String CH,CH2;
             while(sc.hasNext())
             {
                   StringBuilder CH1=new StringBuilder();
                   CH=sc.next();
                   CH2=CH.toUpperCase();
                   CH1.append(CH2);
                   CH1.reverse();
                   System.out.println(CH1);
             }
             f.close();

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.
