Thread: Listing file names in a JList

I have a JList that will list certain files in a directory (may have seen an earlier post, same (JList). It works good, however, it lists the FULL path to the file, that's not what i want, i only want the last part of the full path, so i did this:

String[] files;
 
String Folder = "path";
File fileFolder = new File(Folder);
File[] fileList = fileFolder.listFiles();
for(int i=0; i<=fileList.length; i++){
	files[i] = file[i].toString();
}

But it doesn't work....


If you can also tell me how to list certain file types (like .jar), that would be greatly appreciated.

this was just the code for getting the names of the files then storing them into an array. Then when the JList is initialized, it'll list the contents of that array.

Looking back at this code, I dont see how it made sense to me. i tried using a different code here:

String Folder = "Path";
File jarsFolder = new File(Folder);
File[] jarsList = jarsFolder.listFiles();
for(int i=0; i <= jarsList.length; i++){
	temp = jarsList[i].toString().split("\\");
	jars[i] = temp[temp.length];
		}

attempting to split it by the \ character, which is then stored into a temporary array, then the very last string in the array would be passed into the next value of a permanent array, which the JList will use as its list. But the exception stack (to me) suggests that it doesn't like "\\" :

yeah, i know, like mac for instance. right now i'm focused for Windows, then i can try to see about others. the program uses console commands from windows. i would need to learn terminal commands from mac if i am to expand it to mac as well.
