7.7:Ethical issues around data collection

Privacy Risks: Personal data can be vulnerable to breaches or misuse when stored in systems. Programmers need to protect it.
Protection Methods:
- Delete Data: Remove personal info when it’s no longer needed.
- Minimize Data: Only collect essential information.
- Anonymize Data: Use methods like hashCode() in Java to hide real info.
- Encrypt: Secure data so it can’t be easily accessed even if stolen.

The main goal? Keep personal data safe with smart coding practices.

What can be used in place of the blank to ensure the users data is cleared?

ArrayList<String> userData = new ArrayList<>();
userData.add("John Doe");
userData.add("john@example.com");

// Once you're done using the data
userData.clear(); // Removes all entries
userData = null;  // Sets the variableto null
