FileChannel class

I am trying to finish up a homework assignment and I am having a little bit of trouble. I am using the FileChannel class to copy input from one file to another. My program will compile but I am not for sure what else to do? I think my problem is in creating a file to be copied. I have created a folder sDir and put in a file.Is this all I need to do? I am not for sure how to have my program create the tDir and copy the contents of sDir. Could someone please look at my code and help me?

I think you have made a logical mistake here, which happens to be solved by a syntactical mistake.

You should add a ! before targetDir - you want to create the folder if it doesn't exist, not if it already exists.

Now your code still works because of the ; right after the if. Right now, your code is equal to this:

So if you add the ! and remove the ; you should be fine:
