Write code for a Java class Rectangle with the following fields and methods: Rectangle - width : double - height : double - area : double + perimeter : double + diagonal : double + Rectangle () : void + setRectangle (double w, double h) : void + printRectangle () : void + changeWidth (double w) : void + changeHeight (double h) : void - static computeDiagonal (double w, double h) : double Fields Methods Methods: Rectangle: Constructor, creates a rectangle with width and height equal to zero. setRectangle: Sets the width and height equal to the two parameters. Computes and stores the rectangle area, perimeter and diagonal. printRectangle: Prints the width, height, area, perimeter and diagonal of the rectangle with labels. All values are printed with a maximum of 2 digits after the decimal. Extra Credit (+5): Include a visual representation of the rectangle: ##### #3 ##### Extra Credit (+2): Visual representation works with length of 1 for height and/or width. changeWidth: Changes the width of the rectangle by the given parameter. changeHeight: Changes the height of the rectangle by the given parameter. computeDiagonal: Static function that computes the length of the diagonal of a triangle with height and width as given by its parameters. Main Program: Program first creates a Rectangle object and sets width and height as entered by the user. The program then repeatedly reads commands of print, height, width or quit until the user enters quit. When the user enters print, the program prints the rectangle private data. When the user enters height, the height is changed by a user entered value. When the user enters width, the width is changed by a user entered value. An error message should be printed if none of the legal inputs is entered. There is a sample run on the next page. Your output should follow the given text and spacing. Include a header comment describing the program and comment all variables, control structures and methods in the program. When your program is running correctly, submit your main program class and Rectangle class source files, .java extensions, in the Homework 2 area on Blackboard. Sample run (input in bold): Input Rectangle: Width: 4 Height: 3 Enter quit, print, width, or height: print Rectangle: #### # # #### Width = 4 Height = 3 Area = 12 Perimeter = 14 Diagonal = 5 Enter quit, print, width, or height: height Enter change in height: 2 Enter quit, print, width, or height: width Enter change in width: 1 Enter quit, print, width, or height: print Rectangle: ##### # # # #### Width = 5 Height = 5 Area = 25 Perimeter = 20 Diagonal = 7.07 Enter quit, print, width, or height: quit
