Write a program in Java to perform the following: Using a BufferedReader class and related objects, read a string object consists of 60 words plus some special characters and numbers. Include double space between some words. Include a few $ and % signs in your text. Store that text into a file using proper classes and methods. Call that file fileon.doc which will be your input file then read the contents of that file and perform the following operations using java available methods: Add a new line at the beginning of the text to include your name and the class name (csc 202) Find the length of you text Change the first character of each line to upper case . Find the number and location of all $ sign and re place it with a space. Delete all double spaces Calculate the number of special characters Find the number of lines in your text. Remember each line is terminated by a “.”, find the number of vowel in the last line Count the number of digits in your text. Append a new line consist…
Write a java program to read from a text file called “CarList.txt”. The file includes carModel , carYear, and carPrice for an unknown number of Cars. The file uses a comma-separated file format, as the sample below. The program should write New cars only into an output file called “NewCars.txt”. A car is considered new if its year is above 2019. Finally, the program should print the number of new cars, the most expensive car, and the cheapest car at the end of the output file. The format of the output file should be similar to the given sample.
In Java Suppose you are given a text file that contains the names of people. Every name inthe file consists of a first name and a last name. Unfortunately, the programmer thatcreated the file of names had a strange sense of humor and did not guarantee thateach name was on a single line of the file. Write a program that reads this file ofnames and writes them to the console, one name per line.For example, if the input file (Names.txt) contains:Bob Jones FredCharles EdMarstonJeffWilliamsThe output should be:Bob JonesFred CharlesEd MarstonJeff Williams Sample Output:Enter the name of the input file:Names.txtBob JonesFred CharlesEd MarstonJeff WilliamsFile processing completed.
Please use JAVA code to write the solution, thanks A text file called names.txt contains one name per line, e.g.,AllisonJohnWilliamJohnetc.Names can be duplicated in the file. Write the code that:1. Reads the names line by line.2. Stores each name and the number of times the name appears in one collection.3. Prints the number of different names to the console.4. Prints the names and how many times each name appears on the console.Think about what data structure would work in associating each name with the number of times it appears in the file. You do not need to write imports.
Modify java code for Hw5 (stock,each csv file has headings: Date,Open,High,Low,Close, Adj Close,Volume) to count and print the number of days there is gain (increase from open to close price) of 2% or more of stock price. Also count and print the number of days the High is 30% bigger than Low. Also, find and print the average volume for the trading days where there is gain. Make sure each print occupies a single line, and all lines are lined up such that the label for each information requested is left aligned, and the decimal points are all aligned. import java.util.*; import java.io.*; public class StockData { public static double average(ArrayList<Double> prices) { double total = 0; double average; for (int i = 0; i < prices.size(); i++) { total = total + prices.get(i); } if (prices.size() > 0) { average = total / prices.size(); return average; } else { return 0; } } public static double min(ArrayList<Double>prices) { double min = prices.get(0); for (int i = 1; i…
<<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
Exercise 2:Write a Java program that allows the user to specify a file name on the command line and prints the number of characters, words, lines, average number of words per line, and average number of characters per word in that file. If the user does not specify any file name, then prompt the user for the name.
This is in Java please: A comma separated value (.csv) file has been included to be used for this program. Each line contains two values, a name and a number separated by a comma (except the first line, which contains the titles for the value types). The name is that of a writer and the number refers to the number of works the writer has written. Ex. Jane Austen,6. Each line is an entry and each entry number can be updated by identifying the associated name. Once complete, the following program opens data file allWorks.csv and asks if the user wants to update entries or add new entries. All entries are stored in an array while being read in and updated. The program then writes the array to the file, overwriting the original contents. The following TODO sections must be completed. Open allWorks.csv for reading/input. Locate an entry to be updated by name (use the Java String indexOf() method) Add a new entry if the name isn't found in the file (give the entry a new number) Open file…
This is for Advanced Java Programming Write a test program that reads words from a text file and displays all non-duplicate words in ascending order and then in descending order. - The file is to be referenced in the program, not needing to be used as a command line reference. - The word file is to be titled collection_of_words.txt and included in your submission. Write test code that ensures the code functions correctly.
Write a Java program that opens a file and counts the whitespace-separated words in that file. You may obtain the name of the input file either from the command line or via prompt and user input. Be sure to clearly document the method chosen. You may test your program using any number of text files; however, you must be sure to test your program using the Sample Text File provided at the end (excerpt.txt). Sample Text File There was nothing so VERY remarkable in that; nor did Alice think it so VERY much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to…
