Amend /fine tune small java script program to add different features

I have a .class and .java file already created but would like someone to amend the program/script to have extra features and some changes. This program takes a word and then produces permutations of this word. For instance it will take a word e.g china and then produce a list of the word china with certain changes, for instance substituting small for capital letters, using numbers instead of letters and using special characters instead of letters: Capitals: CHINA ChInA cHiNa chinA Numbers: china1 1china 12china china12 123china china123 Letter substitution: c#ina ch1na ch!na chin3 c#1na c#!na c#!n3 c#1n3 ch1n3 ch!n3 Additional characters added before and after the word: ?china china? ?china? £china china£ £china£ !china china! !china! A second option (which isn't in this program yet) would allow the above words, for instance, china! , to be run through the capital letter changes and letter substitution. So for instance you would get e.g c#ina! , C#in3! , Ch!n3! and so on, and would get a total of 3150 permutations for just the word china (rather than just the short list above). I would like the following done asap: - Change the name of the program to cpp - Have the script automatically save a generated list of permutations to a .txt file on the local machine. - Have an 'option 1' which will generate a quick list of around 10 to 50 words, and an 'option 2' which will produce a longer list with more mutations (say around 3000 words). - Nice to have - an option to put a list of words through the script which will do the same as the above, but rather than a single word, there will be a list of words (in .txt format) which will also produce either a short or long list of permutations. - Correct the error in the existing program which seems to put an accent (like a French accent) over the letter u. This might just be my machine but needs checking. - Ensure that words of between 5 and 8 characters can be entered. Happy for the existing .class and .java files to be completely rewritten if this is easier. I will send the existing .class and .java files to whoever will be awarded the project. I will pay £25 for the completed program. Please don't bid any higher than this! Thanks for looking...
