Develop an application that will read data from an input file,

interpret the data, and generate output to the console.

$$ Complete two classes, Rectangle and RectanGraphic.

$$ Implement the Rectangle class according to the following UML description:

Implement the RectanGraphic class with the following features:

$$ Create the main method.

$$ Read from the text file $$rectangles$.$txt$$ that holds data for constructing several

Rectangle objects.

o A sample $$rectangles$.$txt$$ file is in the project root folder.

o Remember that the default relative filepath starting point is the project root folder

$($one folder above the src folder$).$

$$ Using the file data, create Rectangle objects and print their graphic representation to

the console.

o Reference the example output on the next page:

Rectangle

Data Fields

$-$rows: int

$-$cols: int

$-$filled: Boolean

Number of rows

Number of columns

Defines either a filled or unfilled rectangle

True $=$ filled, False $=$ unfilled

Methods

$+$Rectangle$($int$,$ int, boolean$)$

$+$toString$()$: String

Constructor that will set rows, cols, and

filled

Create and return a String that graphically

represents the Rectangle

For example, when

rows $=3,$ cols $=4,$ and filled $=$ false,

the method creates and returns the string

MadLib

Develop an application that will read data from

two input files, interact with the user, and write results to an output file.

$$ Complete the MadLib class in the madlib package.

A $$Mad Lib$$ is a word game where players fill in blanks with various parts of speech $($like nouns,

verbs, and adjectives$)$ to create a humorous and often nonsensical story. This application allows

the user to create a random Mad Lib.

Complete the MadLib class main method with the following details:

$$ Do not change any provided code. A $//$TODO comment indicates where to begin adding

code.

o Observe the code to recognize: counting Mad Lib files, selecting a random Mad Lib

wordsFile and libFile, printing the names of the files, and creating the words array

$$ Open the wordsFile, libFile, and user input for reading data.

$$ Show the user each word prompt and store the user$$s input into the words array.

$$ Write completed lines to an output file madlib$-$result.txt$.$

o Each line should be no more than $70$ characters $(.$length$()$ of the line String$)$

$$ Print $$View your Mad Lib in madlib$-$result.txt$!$

$$ Close all file streams

Hint: Scanner and PrintWriter will be useful for reading and writing Mad Lib data
