java : Sort Files based on Creation Date

Question

I am trying to read the latest 10 files based on their creation date .

I tried with this code , but it isn\'t working , i mean , it doesn\'t show the new file nam

Answer 1

At least in regular Java version you compare files in the wrong (ascending) order. I multiplied result by -1 and I am seeing latest files first:

return -1* (new Long(((File)o1).lastModified()).compareTo(new Long(((File) o2).lastModified())));

With timestamps the larger one corresponds to the newer file.

Answer 2

Try flipping the comparison order:

return new Long(((File)o2).lastModified()).compareTo(new Long(((File) o1).lastModified()));

This works for me testing locally just now.
