Imagine you're developing an e-commerce application where customers create accounts with varying levels of detail.
Initially, you use a standard constructor for the User class:
public User(String firstName, String lastName, String email, String address, String phone, int age) { // ... }
However, you encounter challenges:
- Registration forms: It's cumbersome to ensure users enter all fields in the correct order, leading to errors and frustration.
- Optional fields: Not all customers provide complete information, but the constructor forces them to.
- Data consistency: Changes to user profiles after registration can cause unexpected issues due to mutable fields.
Implement solution using the Builder Pattern to address the issue.
