Please provide me java code for below problem: Assignment Guidelines: Text messaging is a popular means of communication. Many abbreviations are in common use but are not appropriate for formal communication. Suppose the abbreviations are stored, one to a line, in a text file named abbreviations.txt. For example, the file might contains these lines: lol :) free iirc 4 u ttfn Write a class AbreviationMarker that will read a message from another text file and surround each occurrence of an abbreviation(ignoring case) with <> brackets. Write the marked message to a new text file. For example, if the message to be scanned is: Ttfn, how are u today? Iirc, this is your first free day. Hope you are having fun! :) the new text file should contain: <Ttfn>, how are <u> today? <Iirc>, this is your first <free> day.

* in java* - Write a program that reads words from a text file and displays all the words (duplicates are not allowed) in ascending alphabetical order. - The words must start with a letter. The text file name is passed as a command-line argument
**USING JAVA** Create a project named Chap4-BikeTracker, then create a class (program) named BikeTracker. Write a program that will use a while loop to read in data from a text file named "Bike.txt" and sum the miles biked each day. It will then compute the total miles the person biked and the average miles biked per day. Each line in the file "Bike.txt" contains a day-date, the number of miles biked that day. Study the program "FileSumNumbers" posted with this activity and use it as a guide. Here is the what the file "Bike.txt" should look like, we will create this text file together in class and save it in your project folder so your program can read it.

JAVA (Baby name popularity ranking) The popularity ranking of baby names from the years 1960s to 2010 are stored in files named babynameranking_1960s.txt, babynameranking_1970s.txt,…, babynameranking_2010s.txt (See the attached zip file). Each file contains two hundred lines. Each line contains a ranking, a boy’s name, a number for the boy’s name, a girl’s name, and a number for the girl’s name. For example, the first two lines in the file babynameranking_2010s.txt are as follows: 1 Noah 182,896 Emma 194,667 2 Liam 173,636 Olivia 184,192 · So, the boy’s name Noah and the girl’s name Emma are ranked #1 and the boy’s name Liam and the girl’s name Olivia are ranked #2. 182,896 boys are named Noah and 194,667 girls are named Emma in the 2010s. Write a program that prompts the user to enter the year, gender, and followed by a name, and displays the ranking of the name for the year.Example Run of it.

<<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
*Please use PYTHON to write a code for this problem* Your task is to find all social security numbers listed within a particular file. You are given a file (info.txt) which contains text including some social security numbers. You have to read the file and find all social security numbers within it and output those numbers to a new file (ssn.txt). All social security numbers are of the form XXX-XX-XXXX where X is a digit between 0 and 9 inclusive. The outputted social security numbers should be on separate lines. Note: You may assume Info.txt is in the same folder as your python py file. You should create the required output file in the same folder. Keep in mind, to test this program you will have to create your own Info.txt and save it in the same folder as your python py file.
PARTICIPATION ACTIVITY Consider a file that contains student grades such as the following: Jane Lee Aaron X. Schmidt Frank von Tardy ... 8.5.5: Arrange the code to read one line of input at a time and then scan the line with another scanner. As with the country names, the student names don't have a fixed number of words. To process the input, read one line of input at a time from the given scanner in, then scan the line with another scanner. Add all but the last word from the line to the name, and set the grade to the last word. Mouse: Drag/drop Keyboard: Grab/release spacebar (or Enter). Move 0000.

Can you please help solve this, please as fast as possible 6.20: Word Count (see attached screen print AND input file) Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.Input Notes:There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. DO NOT USE A STRING VARIABLE.Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.
