kewl i just did that, i stored 200 words in a text file, its called dictionary.txt

Great. Now you need to know how to read words from that text file.

This article will show you how. Make sure you also read the comments posted in that thread. After you're done reading that you should try the code and read words from your textfile. Also try to get a random word to display to the screen.
Hint: For the random word display part you may find the java.util.Rando m class helpful.

ok, i just managed to read and print all the words, im not familiar with the java.util.Rando m class so do not know how to display a random word instead of all of them

You should have opened the API docs page for it.

From here there are two ways of going about it.
Read all the words into an ArrayList<Strin g> one word at a time. Then generate a number (using the Random class) between 0 and the number of words in the ArrayList (minus one). If the generated number is n, then displaying the nth string in the list is equivalent to displaying a random string.

P.S Always refuse to write any code if you do not have the API specs with you.

P.P.S We are still just playing around with some stuff here. The next step involves the algorithm which you are going to write.

[araujo2nd]

Okay. Will attempt it first thing tomorrow morning. How exactly should i set out the algorithm. I dont normally use algorithms as i dont really understand how to make them:(.. But once i get the random word to work ill let u know. I hope i can get that by tomorrow morning.

An algorithm is basically just a step by step list of whats going to happen in your program.

its also helpful to make a list of all the things your going to need.
You need to read a file
get user input
display user input as output
etc
etc

I have found recently that when i have a daunting project on my hands if you break it down and say "ok, today I am going to do this and if i have time start this, or polish this" the project seems to flow more smoothly. Sitting down and just starting to hack out code leads to problems. Even though coding it right away might seem like the quickest way to finish the project, its not.

This is a great site to come to for help, you just need to show your doing the work yourself and all the developers, admins, mods and experts are more then willing to guide us:)

i have decided to go with the applet above, most of it was done by me in any case, i have to continue with it because its so close to done, and i rele do not have time to start from nothing, it has to be done by monday with the documentation which will take me hours:(

so all help with my applet would be much appreciated, i would like to change the applet into a java application, i only use NETBEANS and DRJava

I thought you said it was written by a good friend of yours.
Anyway good luck with it.

Edit: Please do not double post. It's against the site rules. Just keep one problem in one thread.

[araujo2nd]

So i take it that u dont want to help me? My friend did not code it, he helped me do the coding. But now that he left i have no help which is why i came here. Anyway thanks

Of course I want to help, but only if you want to do it the correct way.

[araujo2nd]

Sir pls can u just help me from where i am, there is still a lot to do, i rele do not have time and have exams soon:(, i just rele want to get this off my chest, i managed to get it to finally run the applet (needed a main method), but now pls could u just help me in getting a high scores table which stores user name and number of tries, and also the reset button does not work and i have tried everything to fix it...i also have no idea how to get the hangman to appear in the gui

That's because you never designed for any of those things before you started.
So what's your current code now? Use code tags if you're going to post it. (It's the # icon on the reply controls menu when you're posting the code)

My java code is:

Those are two different programs. So which one do you want to work with?

P.S It will have to be one that you understand because you will be making the changes to make it work.

any, whichever 1 i could do quicker i suppose
