5. Declare a class called coordinate. This is to represent 3 dimensional Cartesian coordinates (x, y and z).Define the following methods cumulatively in Java cumulatively:a. Constructorb. Display, to print values of membersc. Add_coordinates, to add three such coordinate objects to produce a resultant coordinate object.Generate and handle exceptions if x, y and z coordinate of the result are zero.d. Main, to show use of the above methods.
Java provides a mechanism that enables a program to be executed from the command line, as an application. Java runtime execution works on the basis that the class executed must have a: (constructor? inner class? method?) named `main’ that is: (final? static? local?) , public and void. This should take an : (StringBuffer? ArrayList? Array?) of Strings as its only argument. Execution is begun by (calling this method? clicking the BlueJ Run button? selecting this method from the dropdown menu?) . Select the correct answer.

in C# i need to Write the program BookExceptionDemo for the Peterman Publishing Company. Create a BookException class that is instantiated when a Book’s price exceeds 10 cents per page and whose constructor requires three arguments for title, price, and number of pages. Create an error message that is passed to the Exception class constructor for the Message property when a Book does not meet the price-to-pages ratio. For example, an error message: For Goodnight Moon, ratio is invalid. ...Price is $12.99 for 25 pages. Next, create a Book class that contains fields for title, author, price, and number of pages. Include properties for each field. Throw a BookException if a client program tries to construct a Book object for which the price is more than 10 cents per page. Finally, using the Book class, create an array of five Books. Prompt the user for values for each Book. To handle any exceptions that are thrown because of improper or invalid data entered by the user, set the Book’s…

In Java: -Using a BST Interface (Binary Search Tree) -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…
