Question

I have a following code in test

public class TestMe {
  private static final String BACKUP_DIR_PATH = "~/backup";

  @Test
  public static void createBackupDir() throws IOException {
    File path = new File(BACKUP_DIR_PATH + "/" + getFolderName()).getCanonicalFile();
    System.out.println(path.mkdirs());
  }

  // returns 2012-07-23
  private static String getFolderName() {
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    Date date = new Date();
    return dateFormat.format(date).toString();
  }
}

When I run this test it returns false

Both backup and 2012-07-23 folder does not exists

What is incorrect here?

Answer 1

It’s probably because Java doesn’t know what the ~ means.

The ~ is a shell expansion, not a valid pathname.
