- If the condition is true then assign “false” to the variable.
- Return the Boolean variable.
- Declare template class.

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.

Write a fully functioning program that correctly uses a list, reads, and writes from/to an external file.
Megan owns a small neighborhood coffee shop, and she has fifteen employees who work as baristas. All of the employees have the same hourly pay rate. Megan has asked you to design a program that will allow her to enter the number of hours worked by each employee and then display the amounts of all the employees’ gross pay. You determine that the program should perform the following steps:
The text that is in the file is stored as one sentence. Incorporate the code that reads the file’s contents and calculates the following:
total number of words in the file
total average number of words per sentence
total number of characters in the file
total average number of characters per sentence
Use function(s) to accommodate this word and character analysis of the file

- Word List File Reader This exercise assumes you have completed the Programming Exercise 7, Word List FileWriter. Write another program that reads the words from the file and displays the following data:• The number of words in the file.• The longest word in the file.• The average length of all of the words in the filearrow_forwardphyton Topics: list and list processing You will write a program to read grade data from a text file, displays the grades as a 5-column table, and then print the statistics (min, max, median, and median). You can assume that the input file only one number per line. You can assume the user always enter a file that exists. The median is the value in the middle of a sorted list. To sort a list, use list.sort() function. It’s computed as below. For a list of odd length, the middle number is just the length divide by 2. For the list, [1,2,3], the median is 2 since 2 is in the middle of the list. The middle index is 3//2, which is 1. Remember that // is the integer division operator. When the length of the list is even, there are two middle numbers. The median is the average of the two middle numbers. For example, [1,2,3,4], the median is (2+3)/2 = 2.5. The two middle indexes for this example are (4//2)-1 = 1 and (4//2) = 2.

Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid.
