Note: screenshots are mandatory.Help with Python coding issue The Linux operating system is a very popular server OS. A network administrator has to protect the login/password files stored on the servers. In Linux there are two important files: /etc/passwd And it contains rows that look like this: root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin user1:x:15:51:User One:/home/user1:nologin user2:x:15:51:User One:/home/user1:nologin user3:x:15:51:User One:/home/user1:nologin This file contains login information. It's a list of the server's accounts that has userID, groupID, home directory, shell and more info. And the second file /etc/shadow, contains rows that look like this: root:$1$TDQFedzX$.kv51AjM.FInu0lrH1dY30:15045:0:99999:7::: bin:*:14195:0:99999:7::: daemon:*:14195:0:99999:7::: adm:*:14195:0:99999:7::: ftp:*:14195:0:99999:7:::…Software Requirements: Latest version of NetBeans IDE Java Development Kit (JDK) 8 Procedure: 1. Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive. 2. Create a new project named LabExer6A. Set the project location to your own folder. 3. Create a simple guessing game (similar to Hangman or Hangaroo). In this game, the user guesses a letter and then attempts to guess the word. 4. Create a Notepad file named words.txt which will store any number of words each written per line. 5. The Java program shall: • randomly select a word from the list saved in words.txt; • display a letter in which some of the letters are replaced by ?; for example, ED??A??ON (for EDUCATION); place the letter in the correct spot (or spots) in the word each time the user guesses a letter correctly; • inform the user if the guessed letter is not in the word; and display a congratulatory message when the entire correct word has been deduced.
