Please create a Java class that has the following data attributes and methods: private int count - number of customers in the array private customer Record[] data - array of customerRecord objects public customer List() constructor that should initialize memory for data array and count value public void getCustomerList(String fileName) - reads a file call fileName which is a text file containing lines (records) of customer data. This method fills the data array with the records from the file. The file will not have more than 100 records and will have the following format (where customer Number is an integer, firstName and lastName are Strings, and balance is a float: customerNumber firstName lastName balance public customerRecord getCustomer(int customerNumber) - returns the object corresponding to the customer with customerNumber. If the customer number is not in the array, return null. public void enter CustomerRecord(customerRecord new_record) - store the customer record into data array public void saveCustermerList(String filename) - save the information stored in the data array to the file called filename
