Question

JAVA PROJECT CREATING GUI WITH ARRAY

Read from a file that contains a paragraph of words. Put all the words in an array, put the valid words (words that have only letters) in a second array, and put the invalid words in a third array. Sort the array of valid words using Selection Sort. Create a GUI to display the arrays using a GridLayout with one row and three columns.

The input file

Each line of the input file will contain a sentence with words separated by one space. Read a line from the file and use a StringTokenizer to extract the words from the line.

An of the input file would be:

Mary had a little lamb
whose fl33ce was white as sn0w
And everywhere that @Mary went
the 1amb was sure to go.

Submitting the Project.

You should have two files to submit for this project:

Project1.java

WordGUI.java

please don't copy the same code as the one uploaded in the chegg

try to write something simple and understandable

please explain every statement please, its for project and i don't want to have similar project like one once in chegg. it would be much apperciated

Answer 1

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU
