6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average…

Write a Java program (Hangman.java) to play the classic word game Hangman. In the game, a word is randomly selected from an array of possible words. Then, the user is prompted to guess letters in the word one at a time. When the user makes a correct guess, all instances of that letter in the word are shown. When all letters in the word have been guessed, the game ends and the score (number of missed guesses) is displayed. A user can play the game multiple times if they choose.   Here is a sample run of a correct program (user input indicated by orange text):Enter a letter in word ******** > cEnter a letter in word c******* > rEnter a letter in word c******r > s       s is not in the wordEnter a letter in word c******r > tEnter a letter in word c****t*r > mEnter a letter in word c*m**t*r > t       t is already in the wordEnter a letter in word c*m**t*r > pEnter a letter in word c*mp*t*r > oEnter a letter in word comp*t*r > eEnter a letter in word comp*ter >…

Write a program in Java that handles the order list for an online retailer. Your program should contain a minimum of three classes: Order Class Display Class Main Class Create a Order Class that uses a queue to hold the orders in the order they were taken. The queue should contain the customer last name, order number, and order total cost. Create a Display Class that will store a copy of the order queue in two arrays. Each array will contain the order list but one will be sorted by name and the other sorted by order number. When a order is taken and stored in the Order Class the program will update theDisplay Class arrays automatically sort them in descending order using quick sort and outputs the the contents to the console upon each entry of new data. Create a Main Class that will handle operator data input and when an order is added or removed, the program will update the Order Class and Display Class. The user will be presented a menu to add a order, remove a order and display…
