- Write a java program that: 1. Create a file with the name "BankAccount.txt" and has the following content (the account name, account number and balance of each account) The file will look like this: Amani Ali 12345432 500 Sarah Mohammad 456663343 4000 Omimah khalid 998787655 2000 Monirah Ahmad 55433424 10000 2. Read the file "BankAccount.txt" content one by one and increase the balance by 50% for each account, then write the result in a new file with the name "UpdatedAccount.txt". The new file content should have the following structure: Amani Ali 12345432 750 Sarah Mohammad 456663343 6000 Omimah khalid 998787655 3000 Monirah Ahmad 55433424 15000 3. Read an account number from the user and search the file "UpdatedAccount.txt", then print all the information of this account if exists, otherwise display a message "this account not found". Note:- Search google to find some of the built-in methods to help you in this program, such as trim(), split(), equals(), Integer.parseInt().Write an application that displays the sizes of the files lyric1.txt and lyric2.txt in bytes as well as the ratio of their sizes to each other. Here is the code so far: import java.nio.file.*; import java.nio.file.attribute.*; import java.io.IOException; public class FileSizeComparison { public static void main(String[] args) { Path textFile = Paths.get("/root/sandbox/lyric1.txt"); Path wordFile = Paths.get("/root/sandbox/lyric2.txt"); // Write your code here } }Directions: Write a program that counts the keywords in Java source code. Revise the program in Listing 21.7. If a keyword is in a comment or in a string, don't count it. Pass the Java file name from the command line. Assume the Java source code is correct and line comments and paragraph comments do not overlap. If you can show (Screenshot) of the file part(how you connect your file with java, name, etc.) I'll appreciate it because I'm struggling a lot with how to make java execute a text file.

Each file signature is an element of your list. Then, try to find out if there is a JPG file in there. If there is a JPG file, print out a True on screen. (File Signature for JPG file is: FF D8 FF DB) The input file is: FSCS360_Midterm_Exam_Part2.txtChallenge 3: Encryption.java and Decryption.java Write an Encryption class that encrypts the contents of a binary file. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded content out to a second file. The second file will be a version of the first file, but written in a secret code. Use a simple encryption technique, such as reading one character at a time, and add 10 to the character code of each character before it is written to the second file. Come up with your own encryption method. Also write a Decryption class that reads the file produced by the Encryption program. The decryption file will use the method that you used and restore the data to its original state, and write it to a new file.
