Alright, so here is my code. What I'm trying to do is be able to select a .txt file and then count the number of times the input word is found. This part works. However, I would also like to count the number of words in the total document as well as the total number of characters in each word. I can't get this part to work and I'm not sure why. I have it working if I input the scanner from a different method, but I can't get it to work with using the same scanner that I'm already using. Is there a way I can reset the scanner for each method it gets to or something? Please help, thanks!

its because scanner class reach to end when counting the letter. It will return 0 for other two.
1) You can solve this by making a string. and pass that string to scanner
2) make a custom class which has three variable count, total count and length. and make function accordingly and check all of three variable in a function.
