Write a program in java that will perform a mail merge Background When companies need to send out the same letter to many different customers, they usually have a form letter which contains place holder codes Then, they will also create a list of data that will be used to fill in the place holders in the form letter A mail merge program is designed to create one copy of the template letter for each person's name that appears in the list Program Description When your program starts, it will be given the name of letter file and the name of a data file Your program should read the letter file, and for each place holder code found in the letter file, you should replace the place holders with data found in the data file Your program should create one output file for each line of data in the data file (in other words, if there are 3 lines of data in the data file, then your program should create 3 output files) Your program must store the all of the integers in an array The maximum number of integers that you can expect is 100, however there may not necessarily be that many Your program should allow the user to continue entering numbers until they enter a negative number or until the array is filled whichever occurs first If the user enters 100 numbers, you should output an message stating that the maximum size for the list has been reached, then proceed with the calculations Input Files The names of the input files are given to your program from the command line, when you type the command to execute your program So, for example, you can test your program with the example files given by typing MailMerge collection1 txt collectionNames1 txt Your starter code includes a file named collection1 txt The contents of this file is as follows Dear , Please remember that the balance on your account ( ) remains unpaid It was due to be paid in full days ago Enclosed is an envelope in which you may mail your payment If, by chance, you have already sent your payment, please disregard this letter and accept our gratitude Thank you In the letter, the codes , , , and indicate the place holders which need to be filled in with customer data Your starter code also includes a file named collectionNames1 txt The contents of this file is as follows Mr ,Smith,102 50,10 Mrs ,James,59 76,14 Ms ,Abrams,147 70,12 Mr ,Sessoms,112 10,18 In the data file, each line of text represents one customer The customer data on one line is separated by commas Thus the first line of data from the data file is Mr ,Smith,102 50,10 and this represents the following data Mr Smith 102 50 10 You should use these files to test your program, and you are also encouraged to create your own TXT files to test with Output Files For the example collectionNames1 txt , there are four lines of data, so your program is expected to create four output files The names of the ouput files should match the names of the customers So for this example, you would create a file named Smith txt , a file named James txt , a file named Abrams txt and a file named Sessoms txt The contents of each of these files should be a copy of the input file, but with the correct data in the place holders So the Smith txt file should look like this Dear Mr Smith, Please remember that the balance on your account (102 50) remains unpaid It was due to be paid in full 10 days ago Enclosed is an envelope in which you may mail your payment If, by chance, you have already sent your payment, please disregard this letter and accept our gratitude Thank you and the James txt file should look like this Dear Mrs James, Please remember that the balance on your account (59 76) remains unpaid It was due to be paid in full 14 days ago Enclosed is an envelope in which you may mail your payment If, by chance, you have already sent your payment, please disregard this letter and accept our gratitude Thank you The algorithm that you can use to create this program is as follows Create an array of Strings to hold the lines of text from the letter file This is a partially filled array, as you will not know how many lines of text will need to be stored Open the letter file Read all of the lines of text from this file and store each line into a different position in the letter array Close the letter file as you will no longer need it Open the data file For each line of text found in the data file Read the line and store it into a simple String variable Use the split method from the String class to split the line of text into four separate strings (the four pieces of data which are separated by commas) The result of this method will produce a String array where each position in the array will contain one of the pieces of data (i e pos 0 will contain the title, pos 1 will contain the name, pos 2 will contain the balance and pos 3 will contain the days) Open an output file where the name of the file should be the customer's name, followed by txt So if the customer's name is Smith then the filename should be Smith txt For each String found in the letter array (the first array) Make a copy of the string (so you don't mess up the original) Using the replace method from the String class, replace with the customer's title Using the replace method from the String class, replace with the customer's name Using the replace method from the String class, replace with the customer's balance Using the replace method from the String class, replace with the customer's days overdue Write the changed line into the output file Close the output file Technical notes, restrictions, and hints There is no keyboard input and no screen output for this program All input data comes from the input files, and all output should be written to files You may assume that the form letter will not contain more than 15 lines Therefore, the partially filled array that you will create to hold the form letter should be created to be size 15 There is a MAXLETTERSIZE constant which is already set to 15 Use it to create the letter array DO NOT attempt to read the entire data file and store the whole thing into an array This file could actually contain more lines of data than you have RAM memory to hold so it may not even be possible to create an array large enough to hold the entire file You should read and process one line of data at a time The starter code contains lines which already correctly get the filenames The filenames are passed into your program from the command line, and will be found in the args array which is a parameter to the main method args 0 will contain the letter file name and args 1 will contain the data file name There is the beginning of a generateLetter method in the starter code You should use this method to create the letter for ONE customer Thus, you will call this method one time for each line of data found in the data file The parameters for this method are as follows letter the array containing the lines of text from the template letter letterSize the used size of the letter array (remember, it's partially filled) data an array containing the four pieces of customer data (title, name, balance, days) Absolutely NO other global variables (class variables) are allowed (except for the keyboard object) Remember that at this stage, COMMENTING IS A REQUIREMENT Make sure you FULLY comment your program You must include comments that explain what sections of code is doing Notice the key word sections This means that you need not comment every line in your program Write comments that describe a few lines of code rather than over commenting your program You MUST write comments about every method that you create Your comments must describe the purpose of the method, the purpose of every parameter the method needs, and the purpose of the return value (if the method has one) Build incrementally Don't tackle the entire program at once Write a little section of the program, then test it AND get it working BEFORE you go any further Once you know that this section works, then you can add a little more to your program Stop and test the new code Once you get it working, then add a little bit more Make sure you FULLY test your program Make sure to run your program multiple times, inputting combinations of values that will test all possible conditions for your IF statements and loops Also be sure to test border line cases
