Is it giving you an error or something? If so, what is it?

The only thing without seeing your error is the comment above your addPost() method in your Forum class never closes. It starts with "/*" so just change that to "//" and you should be all set if that's causing problems..

i got rid of it and its still not working

this is what it gave me for errors

./Forum.java:13: error: unclosed comment /* Uncomment this when you are prompted to do so ^ ./Forum.java:28: error: reached end of file while parsing ./Main.java:19: error: cannot find symbol forum.addPost(post); ^ symbol: method addPost(ForumPost) location: variable forum of type Forum Note: JavaTester.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 3 errors

Based on the error you're getting. That should be the solution.. Maybe try closing out of workspaces and coming back to it. Also look for anymore open comments that arent closed..
