2. Now write a program named filereader.py that reads and displays the data in friends.txt. This program should also determine and print the average age of the friends on file. That will require an accumulator and a counter. Use a while loop to process the file, print the data, and modify the accumulator and counter. Then close the file and use an f-string display the average age accurate to one decimal place. See the Sample Output..

For example, if the filename is "data.txt", and the file content in "data.txt" is Dumond, Kristin Larson, Lois the output should be: KD LLHi, i need help with this program using Java. Write a program that reads the file AdventuresInWonderland.txt one line at a time and prints the count of each of the five vowels followed by a count of the consonants in the file. Coding requirements: Read the text from the file AdventuresInWonderland.txt. Use a single while loop to read the lines of the file. Use a single for loop to iterate over the characters in each line. Use a single switch statement to determine which counter to increment. Notes: The input may contain punctuation and digits as well as letters. Account for both uppercase and lowercase letters. Character.toLowerCase(ch) returns the lowercase character corresponding to ch(char ch). Character.toUpperCase(ch) returns the uppercase character corresponding to ch(char ch). Character.isLetter(ch) returns true when ch is an alphabetic letter Expected output: Vowels found: a: 324 e: 455 i: 251 o: 300 u: 109 Consonants: 2384 Example: If one creates a Scanner as…The program will prompt the user to enter the file names for a source input file and an output file along with two strings, one to be found in the source file and a string that will replace each occurrence of that string in the file. source file: this is the text file that your program will read and search for the target string to be replaced output file: this is the file that will contain the source file after all of the occurrences of the target string have been found and replaced by the replacement string target string: this is the string your program will search for in the source file to locate all occurrences of the string replacement string: this is the string that will replace each occurrence of the target string in the source file I cant use the replace method, count method, split method, range() function, or lists in my solution is there any other method to use to get this.
- Write a program named filemaker.py that will be used to store the first name and age of some friends in a text file named friends.txt. The program must use a while loop that prompts the user to enter the first name and age of each friend. Each of these entries should be written to its own line in the text file (2 lines of data per friend). The while loop should repeat until the user presses Enter for the name. Then, the file should be closed and a message should be displayed. SAMPLE OUTPUT Enter first name of friend or Enter to quit DennyEnter age (integer) of this friend 24Enter first name of friend or Enter to quit PennyEnter age (integer) of this friend 28Enter first name of friend or Enter to quit LennyEnter age (integer) of this friend 20Enter first name of friend or Enter to quit JennyEnter age (integer) of this friend 24Enter first name of friend or Enter to quitFile was createdThe following program is supposed to read the length and width of a rectangle from a file named input.txt and print the area and perimeter of the rectangle to a file named output.txt.
