Glich in the internet..Design and implement a basic console application that implements the requirements stated below.

1. Minimum requirements:
   • Design and implement your main method, in the class Lab4, in the file Lab4.java, to perform the following:
     1. If the file to load is not present on the command line, prompt the user using a JOptionPane for the file to process.
     2. Using an instance of the RectangleFile class:
        1. Load the final file into a Rectangle[]
        2. Output the populated Rectangle[] to System.out
        3. Find the minumum and maximum Rectangles in the Rectangle[]
   • Modify the Rectangle class from Lab 3 as follows:

1. • • Add a contructor that takes the width, length and color
     • Add an accessor method for the color
     • Add a mutator method for the collor
   • Design and implement class named RectangleFile, in the file RectangleFile.java, with the following methods:
     • Default no argument constructor
     • loadArrayFromFile:

• § /**
• § * If the given file exists:
• § * - count the number of lines in the file
• § * - create an appropriate size Rectangle[] to populate
• § * - read in the file one line at a time where each line is formatted as:
• § * width length color
• § * - create a new Rectangle from the input and add it to the Rectangle[] that will be returned
• § * - output a message to System.out with each new Rectangle object added to the array
• § * If the given file does not exist, write an appropriate error message to System.out
• § * @param filename the name of the file containing the raw Rectangle data
• § * @return the array of Rectangle objects created from the raw data in the file or null on error
• § * @throws java.lang.Exception - NOTE: we have not covered Exceptions yet so just add throws Exceptions on faith.
• § */
• § public Rectangle[] loadArrayFromFile(String filename) throws Exception

1. • • dumpArray:

• § /**
• § * Validate the rectangles array and then for each Rectangle in the array, add its toString output to
• § * a StringBuffer
• § * @param rectangles the array of Rectangle objects to process
• § * @return a single string with each Rectangle object's toString result on its own line
• § */
• § public String dumpArray(Rectangle[] rectangles)

1. • • findAndOutputMinMaxRectangle:

• § /**
• § * Validate the rectangles array and then iterate through the array to find the
• § * Rectangle object with the minimum and maximum area and the index in the array
• § * they were found out and output to System.out the search results to include the
• § * index, the Rectangle object and an appropriate message.
• § * @param rectangles the array to process
• § */
• § public void findAndOutputMinMaxRectangle(Rectangle[] rectangles)

1. • • countLinesInFile:

• § /**
• § * Read the given file line at a time and count all non-empty lines read. Before returning, output a
• § * message to System.out detailing the file that was processed and the number of lines counted.
• § * @param fileToCountLines the File instance to process
• § * @return the number of non-empty lines in the file
• § * @throws java.lang.Exception - NOTE: we have not covered Exceptions yet so just add throws Exceptions on faith.
• § */
• § private int countLinesInFile(File fileToCountLines) throws Exception

1. • Sample System.out output when the file was found:

• o Given the following contents in a file named rectangles.txt:
• o 1.5 21.5 red
• o 2.5 22.5 white
• o 3.5 23.5 blue
• o 4.5 24.5 red
• o 5.5 25.5 white
• o 6.5 26.5 blue
• o 7.5 27.5 red
• o 8.5 28.5 blue
• o 9.5 12.5 red
• o 10.5 11.5 blue
• o 11.5 10.5 red
• o 12.5 9.5 white
• o 13.5 8.5 white
• o
• o and executed with the command line: java Main rectangles.txt
• o
• o Produced the following output:
• o
• o countLinesInFile: File=rectangles.txt Lines=13

1. • Sample System.out output when the file was not found:

• o Executing with the command line with an invalid filename: java Main rect.txt
• o
• o Produced the following output:
• o
• o loadArrayFromFile: rect.txt could not be found
• o dumpArray: The array is null!
• o findAndOutputMinMaxRectangle: the array is null
• o

1. Minimum general design requirements:
   • You will follow the Java naming conventions, i.e., class names are in Pascal case, i.e., CheckingAccount; methods and variables are in Camel case, i.e., getOverdraftLimt().

just this one

No problem! I now you will!

Thanks!!!

I will do this once I get home!

THANKS!!!

Sorry I have been having internet problems. Can I get the password now?

Thanks!

ÏI keep getting the following:

Lab4.java:98: cannot find symbol
ÏϧÏsymbol : class RectangleFile
ÏϧÏlocation: class Lab4
ÏÏ§Ï RectangleFile rf = new RectangleFile();

ÏRectangleFile.java:34: cannot find symbol
ÏϧÏsymbol : class Rectangle
ÏϧÏlocation: class RectangleFile
ÏÏ§Ï public Rectangle[] loadArrayFromFile (String filename) throws Exception

Extracting Lab4.class Blocked by Windows

Extracting Lab4.class Interrupted

ÏLab4.java:98: cannot find symbol
ÏϧÏsymbol : class RectangleFile
ÏϧÏlocation: class Lab4
ÏÏ§Ï RectangleFile rf = new RectangleFile();

when I complie rectangle I get

Rectangle.java:98: cannot find symbol
ÏϧÏsymbol : class RectangleFile
ÏϧÏlocation: class Lab4
ÏÏ§Ï RectangleFile rf = new RectangleFile();

And then when I try and save the two lab4 overides andwants to be saved as rectangle?

I'm sorry I have been such a pain. I will try later when I am at home.

THank you again!!!

IT WORKED!!!!!

This is what was posted for the last one....can you help me to see if this one is similiar? DOes that make sense?
