1) What is one main disadvantage of an ArrayList? 2) Write a Java statement to create an ArrayList called list to hold 25 integers. 3) What is the type of the ArrayList defined in question number 2? 4) Write a for loop to initialize the objects in the ArrayList created in question number 2 above to -1.

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)…

A file USPopulation.txt contains the population of the US starting in year 1950 and then each subsequent record has the population for the following year. USPopulation.txtDownload USPopulation.txt Write a program that uses an array with the file that displays these in a menu and then produces the results. This is not an Object Oriented Program but should be a procedural program, calling methods to do the following: 1: Displays the year and the population during that year 2. The average population during that time period (Add up the populations of all records and divide by the number of years). 3. The year with the greatest increase in population - print the year and that population and that amount. To figure this out, compare the difference in population before of say year 1950 and 1951, store that difference somewhere. Compare 1951 with 1952, find that difference. Is that difference greater than the stored difference? If so, move that the the maximum place. 4.…

JAVA Program   Homework #1. Chapter 7. PC# 2. Payroll Class (page 488-489) Write a Payroll class that uses the following arrays as fields: * employeeId. An array of seven integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 * hours. An array of seven integers to hold the number of hours worked by each employee * payRate. An array of seven doubles to hold each employee’s hourly pay rate * wages. An array of seven doubles to hold each employee’s gross wages The class should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the employeeId array. That same employee’s pay rate should be stored in element 0 of the payRate array. The class should have a method that accepts an employee’s identification…

In this project you will generate a poker hand containing five cards randomly selected from a deck of cards. The names of the cards are stored in a text string will be converted into an array. The array will be randomly sorted to "shuffle" the deck.  Each time the user clicks a Deal button, the last five cards of the array will be removed, reducing the size of the deck size. When the size of the deck drops to zero, a new randomly sorted deck will be generated. A preview of the completed project with a randomly generated hand is shown in Figure 7-50.
