Take a look at below code which check file in the folder and rename it.

File dir = new File("D:/xyz");

if (dir.isDirectory()) { // make sure it's a directory
    for (final File f : dir.listFiles()) {
        try {
            File newfile =new File("newfile.txt");

            if(f.renameTo(newfile)){
                System.out.println("Rename succesful");
            }else{
                System.out.println("Rename failed");
            }
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
