Program 1 Two files are required, a data class named Book and an executable class named TestBook. Class Book • has instance data members (all private) String title, String author, int pages, double price. • has a public static int variable named numBooks with an initial value of zero. • has a parameterized constructor that will be used to make a Book object and assign values to its data members, and increment numBooks. • has a no-arg constructor that increments numBooks. • has getters and setters for all instance data members. • has a toString() method that returns a string displaying the state of a Book instance. • Use the numBooks variable to report the number of books instantiated. Class TestBook This class needs a main method and two more methods. In main: 1. create an array capable of holding six Book objects. 2. use the parameterized constructor to specify the data in the first four elements of this array 3. use the no-arg constructor to create the two remaining books in the…

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…

In Java inputs and output values can easily be manipulated, for example when dealing with money the value should always be formatted to 2 decimals or another use is separating of words in even spaces, line breaks and etc. Your task is to prompt the user for 2 numbers one integer the other decimal and print their product in money format. The program should also take in two words delimitated by @ symbol.
