Referring to the previous DecimalFormatting class, there were three lines of code. static DecimalFormat df = new DecimalFormat("#,##0.00; (###0.00)"); static DecimalFormat df1 = new DecimalFormat("##0.0%"); static DecimalFormat df2 = new DecimalFormat("$ #,###0.00;$ (# ###30.00)"); Learning item 1: these are considered global variables (df, df1 and df2) because they are ahead of main, outside of a method and at the class level. Learning item 2: they are all declared "static" because they are referred to and used by main(...), which is a static method. Your question: df, df1 and df2 are considered to be direct object instances of which class? java Ojava.text DecimalFormat NumberFormat

Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).

INSTRUCTIONS: Write a C++ script/code to do the given problem. Write a class called profileID, which has data members firstName,lastName, age, birthday and ageCompany (the age when you entered in the company). Remember to use set and get methods to access the data members this time. Also, write another class called bonusAward that has a method getBonus()with arguments yos and etype which are both integer data types. This method calculates the bonus received by an employee using this formula: yos*1000 + etype*1000. Write two derived classes, ASE and SE, using multiple inheritance usingprofileID and bonusAward as parent classes. Both classes must have amethod named getyos()that returns the yos of an employee using the formula age–ageCompany; and a method named getetype() which returns a constant based on the employee type. For ASE, the constant is 10 while for SE that constant is 20. Last, write a main program where you instantiate ASE as employee1 and SE as employee2. Get their…

In C++ code. Create a class called publication that stores the title (char array) and price (float) of a publication. From this class derive two classes: book, which adds a page count (int) and tape, which adds a playing time in minutes (float). Each of the three classes should have a getdata() function to get its data from the user using input from the keyboard and a putdata() function todisplay the data. Write a main function that creates an array of pointers to publication. In a loop, ask the user for data about a particular type of book or tape to hold data. Put the pointer to the object in the array. When the user has finished entering data for all the books and tapes, display the resulting data for all the books and tapes entered, using a for loop and a single statement such as: pubarr[j] -> putdata(); To display the data from each object in the array.

Help of what these errors mean. In C# • Create a Class, named Student, to hold properties of Student Last Name, Student First Name, Student ID (9 digits), Course Prefix and Number, and the tests (Test 1, Test 2, Test 3, Test 4). Create appropriate setter and getter accessors, and constructors. Use access modifiers. Example: First Name : Pat Last Name : Smythe Student ID : ABC111333 Course Prefix : CIST Course Name : 2431 Test 1 : 100 Test 2 : 90 Test 3 : 80 Test 4 : 88 • Prompt the user for the Student Last and First Name, Student ID, Course Prefix and Number and the tests. • Include at least one exception handling function. • Use an array to store the 4 test grades. • Use a looping structure to populate the array. • Calculate the numeric average based upon the 4 equally-weighted numeric grades. • Display all the data for each of student using a looping structure. • Display the numeric average for each student. • Create a function that will convert the numeric average to a…
Question 1 Write a Python class named Histogram that keeps track of how many times each unique element in a given sequence occurs. This class will implement the following interface: • Histogram( sequence ) will create a histogram of all elements occurring in the given sequence. This class cannot use the dict or collections.Counter types to create instance or class variables in order to implement the following specifications! If it does, the grade for your solution will automatically be zero! However, in some cases, your code will have to return dictionaries. So note the difference between the two specifications! • get( element-None, default-e ) will return how many times given element occurs in the histogram. If no element is specified, then the get () function will retum a dictionary where keys are elements and values are number of times a given element occurs in the sequence provided to the initializer. For example, given h - Histogram( "aaabbc" ) then h.get( "b" ) should return 2,…
