Description
Objective:
Design and implement a word unscrambler game in Java.
Project Details:
Write a program named WordUnscrambler.java that reads in a random word from a file called words.txt (note the lack of capitalization) that you provide. The file should contain one word per line. To read a random word you can generate a random number between 1 and the number of lines, and skip n-‐1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times. Display the scrambled word with character indexes on top. Offer the user a menu with the following choices:
- Enter 1 to swap a pair of letters
If this option is selected prompt the user to enter two indexes and swap the letters. Print an error message if the indexes are invalid. If the word is unscrambled successfully print a congratulatory message containing the word and the number of steps it took to unscramble. Otherwise display the new word, and offer the menu again. • Enter 2 to solve
If this option is selected print the unscrambled word and quit.
- Enter 3 to quit
If this option is selected quit.
Example run:
| ——— 0123456 rpocjet ———
Enter 1 to swap letters. Enter 2 to solve. Enter 3 to quit.
1 Enter the indexes separated by spaces 0 1 ——— 0123456 procjet ———
Enter 1 to swap letters. Enter 2 to solve. Enter 3 to quit.
1 Enter the indexes separated by spaces 3 4 |
