Question

I have to find the file names in tree view which has placed under folder or sub directories.

For example,assume directories called A,B,C…

A–B/testb.txt–C/testc.txt/……E—G/testg.txt

How to get all the file names from above directories using Java?

Answer 1

• Create a file object for the topmost directory
• Get a list of all the File objects contained in that directory
• Iterate over each file:
  • If the File object is of type file, then print out its name
  • If the File object is of type directory, then repeat the above steps

Refer the File javadocs for more details, reference snippet elsewhere, post your attempt and we’ll help you out.
