directry cannot simply delete if it has the files so you may need to delete the files inside first and then directory

public class DeleteFileFolder {

public DeleteFileFolder(String path) {

    File file = new File(path);
    if(file.exists())
    {
        do{
            delete(file);
        }while(file.exists());
    }else
    {
        System.out.println("File or Folder not found : "+path);
    }

}
private void delete(File file)
{
    if(file.isDirectory())
    {
        String fileList[] = file.list();
        if(fileList.length == 0)
        {
            System.out.println("Deleting Directory : "+file.getPath());
            file.delete();
        }else
        {
            int size = fileList.length;
            for(int i = 0 ; i < size ; i++)
            {
                String fileName = fileList[i];
                System.out.println("File path : "+file.getPath()+" and name :"+fileName);
                String fullPath = file.getPath()+"/"+fileName;
                File fileOrFolder = new File(fullPath);
                System.out.println("Full Path :"+fileOrFolder.getPath());
                delete(fileOrFolder);
            }
        }
    }else
    {
        System.out.println("Deleting file : "+file.getPath());
        file.delete();
    }
}
