- Part III Write a program that gets integer input from user until the user gives a value bigger than 50 by using while loop. Note: Do not compress your files, submit only java files. Note: Do not forget to justify your answers with comments.2. Message Decoder Create a MessageDecoder program that reads from a file (one character at a time), and writes all non-numeric characters to a file called DecodedMessage.txt, displaying a secret (and motivational) message. ***Hint: .read() will return an int, but this can be type cast as a char. int and char are interchangeable (via type-caşting). You could run a loop on a condition like charInFile != (char) -1 Don't forget that -1 is a special character that denotes the end of a file!<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. 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 contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file
- PYTHON!!!!! A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AM Enter the input file name: example.txt AM 3 I 3 SAM 3 The program should handle input files of varying length (lines). Program produces correct output given input, test 1 Test Case: Test program with example.txt Input: example.txt Results: AM 3 I 3 SAM 3 Program produces correct output given input, test 2 Test Case: Test program with test file 2 Input: test.txt Results: 3/4 1 98 1 AND 2 GUARANTEED 1 INDEED 1 PERCENT 1 SUCCEED 1 WILL 2 YES 1 YOU 2*Code in Python Write a script named dif.py. This script should prompt the user for the names of two text files and compare the contents of the two files to see if they are the same. If they are, the script should simply output "Yes". If they are not, the script should output "No", followed by the first lines of each file that differ from each other. The input loop should read and compare lines from each file, including whitespace and punctuation. The loop should break as soon as a pair of different lines is found. Below are examples of the program input and output along with relevant files: one.txt: This is text. abc 123 sameAsOne.txt: This is text. abc 123 differentFromOne.txt This is text. xyz 123 Comparing files that are the same: Enter the first file name: one.txt Enter the second file name: sameAsOne.txt Yes Comparing files that are different: Enter the first file name: one.txt Enter the second file name: differentFromOne.txt No abc xyzwordCountDistinct.py: Write a program that reads words from a file (filename given as a command-line argument) and prints the number of distinct words. Words that differ only in case should be considered to be equivalent.For example, using the input: If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print 18.
- Using Java: A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: the name of the client the service sold ( Dinner, Conference, Lodging) the amount of the sale the date of the event. Write a program that reads such a file and displays the total amount of each service category. Display an error if the file does not exist or the format is incorrect.wordSort.py: Write a program that reads words from a file (filename given as a command-line argument) and prints them in (case insensitive) sorted order. For example, if the input file contains:If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print (one word per line, compressed here for brevity):a baby Check DJ hook I'll Ice ice If it it my outproblem revolves solve the there's while yoTask 3: Summary We would like to be able to generate a summary for each logfile to give us a rough idea of its contents. Instructions Create a file called Summary.java. As with Task 1, open the file for reading in a try-catch block. Read through the entire file, counting how many of each message/event type occurs. Print out a summary with the count of each event/message type. As a sanity check: the total number of message/event type counts should equal 1000. Hint: a useful method could be String.split. Sample Input/Output Example 1: Summary -------------------- Notifications: 322 Warnings: 326 Errors: 352 Cannot find logfile! Exiting...
- JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…Question 1 Write a Java program that prompts the user to enter a file name. Then the program counts and displays the number of letters and words in the file. You may use the following code fragment to extract and count the letters and words. int charchterCounter - 0; int wordsCounter - 0; String line; Scanner fileContent while (fileContent.hasNext ()) { line = fileContent.nextLine (); if(line.trim ().length () > 0) wordsCounter = wordsCounter + line. split (" ").length; for (int i - 0; i < line.length (): i++) if (Character.isLetter (line.charAt (i))) charchterCounter++ENGAGE MINDTAP -Using a Counter-Controlled while Loop in Java Using a Counter-Controlled while Loop ? Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions 1. Ensure the file named Multiply.java is open. 2. Write a counter-controlled while loop that uses the loop control variable to take on the values O through 10. Remember to initialize the loop control variable before the program enters the loop. 3. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. 4. Execute the program by clicking Run. Record the output of this program. Grading When you have completed your program, click the Submit button to record your…
