{
    File oldfile = new File(oldName);
    if(!oldfile.exists())
    { 
        System.out.println("File or directory does not exist.");  
        return false;
    }
    File newfile = new File(newName);
    boolean reName = oldfile.renameTo(newfile);
    if(!reName )
    {
        System.out.println("File or directory does not rename successfully.");
        return reName ;  
    }else{
            System.out.println("File or directory rename is successfully.");
            return reName;
     }
}
