USING JAVA and NOTTT using BufferedReader or BufferedWriter
Write an application that implements a simple text editor. Use a text field and a button to get the file. Read the entire file as characters and display it in a TextArea. The user will then be able to make changes in the text area. Use a Save button to get the contents of the text area and write that over the text in the original file.
Hint: Read each line from the file and then display the line in the text area using a method, maybe called appendText(aString). A method, maybe called getText, will return all of the text area in a string that then can be written to the file.

JAVA Write an application to test the HuffmanTree class. Your application will need to read a text file and build a frequency table for the characters occurring in that file. Once that table is built create a Huffman code tree and then a string consisting of 0 and 1 characters that represents the code string for that file. Read that string back in and re-create the contents of the original file. Prompt the user for file name. Read the file,...
Create a New Java Project called YourLastNameUpperCase. Write a program that asks the user for the names of two files. The first file should be opened for reading and the second file should be opened for writing. The program should read the contents of the first file, change all characters to uppercase, and store the results in the second file. The second file will be a copy of the first file, except that all the characters will be uppercase. Use...
create a new Java application called "CheckString" (without the quotation marks) according to the following guidelines. ** Each method below, including main, should handle (catch) any Exceptions that are thrown. ** ** If an Exception is thrown and caught, print the Exception's message to the command line. ** Write a complete Java method called checkWord that takes a String parameter called word, returns nothing, and is declared to throw an Exception of type Exception. In the method, check if the...
A. Create a java program that generates 1000 random integers. Write the 1000 random integers to a file using the Formatter class. B. Create a second java program that opens the file with the 1000 integers using the Scanner class. Read in the integers and find and print out the largest, smallest and the average of all 1000 numbers. C. Repeat A from above but use the BufferedWriter class B. Repeat B from above but use the BufferedReader class.
