The intent of the DSL is to specify commands which forward to another object, but which always return the receiving object as the result of the command. A common pattern of returning the receiving object can be difficult to enforce. Direction provides behavior similar to the Ruby standard library Forwardable. Write an example from Direction:

Write code in java object oriented programming. You are required to create a simple command line application that allows users to do two basic things, (1) create an email comprising of properties, to, from, subject and message and (2) to create a book chapter that has the properties of chapter title, chapter number and chapter contents. When the program begins its execution, your program should first ask the user for the sender and receiver for the email, its subject and lastly its message; it should then display the entire email in a well-structured format. Second, the program should ask the user for the book chapter name, its number and finally the contents that go in the chapter. At the end, display the book chapter along with all the properties.
Write a C# program that implements a class of your own design. Your class should have minimum of five data items (with at least one string, one integer, and one double), get/set accessor methods for each of the data items, a default constructor, and a display method. (a) you must provide code in your Main() method to declare and demonstrate the use of all the components of your class. Once you have done this, Please place an appropriate C# comment in your code identifying which of the following items you are attempting to do. You will need to provide code in your Main() method to test any of the following items you attempt as well. b. add a constructor that will allow the user to specify the data items upon creation of the object. c. modify the set accessor method for an integer data item to restrict the value entered to a value between 0 and 100. d. modify the set accessor method for a double data item to restrict the value to a non‐negative number (0.0 or higher) e. modify the set…
