Thread: Writing a word jumbler program.

This program grabs a random word out of a .txt file and jumble the word and then gives the user 4 options: guess, hint, new word, or quit.
my program compiles and works, however I am having a problem with the switch statement when I try to get a new word
the program grabs a new word and prints it to the screen but keeps the old jumbled word. I want it to jumble the new random word. I used the same code to jumble the word the first time as I do in the switch statement.

I have tried to set the string jumble to null but when I do this the program does not print out anything except the new word.
Any input would be great!
Thanks in advance.
One more note I am not using separate methods for a reason. When I originally wrote this program it was for a school project that I had before we were introduced to methods. I am redoing this project to see if I can improve it.
