Common errors
- Forgetting parentheses on computeDigest. Write Utilities.computeDigest(), not Utilities.computeDigest or computeDigest by itself.
- Skipping dots between chained calls. Each step needs a dot, like Utilities.computeDigest().
- Adding spaces where they do not belong. Write Utilities.computeDigest(), not Utilities .computeDigest(), Utilities.computeDigest (), or Utilities . computeDigest().
- Wrong capitalization. Use Utilities and computeDigest, not utilities or computedigest.
