Solve the crossword

Question

I was solving crossword on android, found that i can make a program to find words off a list of words from the link i used in my previous project.

I have the following things available (for example)
1. Number of letters
2. A few letters here and there

So now i need to find the word with letters i have and count of letters.
A program that takes in number of letters (suppose n) and scans every n letter words with the combination of available letters in the word at the right place

Ex. @@R@@A@T
n=8
Available letters R at 3, A at 6 and T at 8
So the program compares way through the list for this combination and get as many words existing.
So i can compare the meaning of those words with the crossword clue and voila it's PORTRAIT.

I know it's possible.. Setting '@' as a varying string.. Need to break every word on the website into number of letters and letters to compare first.

I pop up on this application when i notice a chance to play with codes. I'm not a coder but have the urge to learn.

Thank you.
