Question

Name your project and class Lab5. Using JOptionPane, write a program that prompts the user whether they want to specify a number between 1 and 7 or have the system generate a random number in that range. If the user wants to specify the number, prompt them for it and verify its validity. Otherwise generate a random number between 1 and 7. Display the number to the user. Once you have the number, open the lab5.txt file that you copied earlier and read that numbered record; for example, if the number was 3, read the third sentence from the file. Display the sentence to the user. Finally, reverse the order of the sentence; that is, take the last letter of the sentence and make it the first, proceeding all through the sentence. Display the reversed sentence.
