(Intro to Java) Tracking CustomersThis program will read in a series of names, along with an associated gender, from an input file of unknown length.The program uses a while loop to read in each name from the file by using the hasNextLine() method from the Scanner class.Please use a while loop for practice, although you could also write this assignment using a for loop to read from the file.As you read in each name, you will store it in an array, along with a title (Mr. or Ms. or Mx.) dependent on the stated gender.The first line of each file will contain the number of names contained in the file (hint: this is the same structure as the input file in your assignment 18.2).Additionally, this program should have two methods, as follows:The first method:The method is named extractInitialIt takes a String parameterIt extracts the first letter (initial) from the String parameterIt returns a char for the initial.Note: You must write a complete Javadoc for this method to receive full credit.The second method:The method is named printArrayIt takes an array of Strings as a parameterIt has a second String parameter which is a file nameIt opens up a new PrintWriter and connects it to the file passed in as a parameterIt prints out the array to the file using a for loopIt closes the PrintWriterIt returns nothingHint: You will need to update the method signature to throw an IOException.Note: You must write a complete Javadoc for this method to receive full credit.Part of the trick of this assignment will be to determine the appropriate time to call each method.Copy and paste the starter code below into a new file called TrackCustomers.java/** * @author * */import java.util.Scanner;//add an import statement herepublic class TrackCustomers{ /** * Write the javadoc comment for extractInitial here */ public static char extractInitial(String customer) { return '\0'; //replace this line when you write the method } /** * Write the javadoc comment for printArray here */ public static void printArray(String[] customers) //update signature of method { return; } public static void main(String[] args) { String first_name, last_name, gender; final int ARRAY_SIZE; final String INPUT_FILE; final String OUTPUT_FILE; System.out.println("Welcome to Customer Tracker!
