CIS355A iLab 5 GuessGame and Text File I/O Java Programs
In this lab you will create a single program that creates and reads a sequential file. All outputs must be GUI-based without using JOptionPane.
Program files for each of the following two programs
2. Text File I/O
STEP 1: GuessGame
Write a program named GuessGame.java that plays the game “guess the number” as follows: Your program chooses the number to be guessed by selecting an integer at random in the range 1–1000. The program then displays the following in a label.
I have a number between 1 and 1000 — can you guess my number?
Please enter your guess: ____________________
A JTextField should be used to input the guess. A JButton must be provided to allow the user to press each time a guess is entered. As each guess is input, the background color should change to either red or blue. Red indicates that the user is getting warmer, and blue indicates that the user is getting colder. A JLabel should display either Too High or Too Low to help the user zero in on the correct answer. When the user gets the correct answer, Correct! should be displayed, and the JTextField used for input should be cleared and changed to be uneditable. Also, a JButton should be provided to allow the user to play the game again. When the New Game JButton is clicked, a new random number should be generated and the input JTextField changed to be editable. A JButton must be provided to allow the user to exit the application. Also provide a count of the number of guesses the user entered when the correct number is guessed.
STEP 2: Text File I/O (20 points)
Write a program called TextFileIO.java to create a file named numbers.dat. Then create an algorithm that writes all even numbered integers from 1 to 100, separated by a comma. After the file has been created, close and reopen the file and display the results to the screen. After the results have been displayed append the odd number integers from 1 to 100, separated by a comma to the end of the file. Reopen the file and display the results. The contents of the file should be the even numbers from 1 to 100 separated by a comma followed by the odd number from 1 to 100 separated by a comma. The output of this program would be something like the following
