Design and implement a word unscrambler game in Java.

Instructions
Your program should read 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

At least 10 different words

Each word should have at least 5 letters

Words should have variable lengths

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 (mandatory use of a loop). Display the scrambled word with character indices 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 indices and swap the letters. A space should separate the two indices. Print an error message if the indices 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.
