3/12 - Bank Management System | Java Project | Creating Signup class

Frame and Component Development
📌 The session focuses on creating and implementing various UI elements within a frame structure, including text fields, labels, and radio buttons, referencing a previous design structure.
📌 Specific UI components being implemented include fields for Phone Number, Email, Date of Birth (using a calendar import), Marital Status (radio buttons), and City.
📌 Implementation details involve setting frame locations (e.g., $30$ to $1000$ units high) and managing component inheritance or structure from parent frames.

Handling Input Fields and Logic
📱 Code refinement is discussed, particularly addressing the generation of large random numbers for phone input, which requires modulo operation to constrain the size.
📱 Logic is implemented for the Marital Status radio buttons (Married, Unmarried, Other), ensuring that only one selection is possible by grouping them into a `genderButtonGroup`.
📱 Text fields are being defined using classes (e.g., `nameTextField`) and configured with specific styles like bold font family and size adjustments (e.g., size $14$ or $18$).

Calendar Integration and Styling
📅 A calendar import (`com.toedter.calendar.JDateChooser`) is introduced for the Date of Birth field, requiring specific imports and configuration within the Java code structure.
🎨 Styling adjustments include setting component background colors (e.g., changing from black to white background) and ensuring text and UI elements display correctly without overlapping or visual glitches.
🎨 A final 'Next' button is added at the bottom of the frame, styled with specific dimensions and positioned correctly using percentage-based offsets.

Key Points & Insights
➡️ Reviewing the structure of inputs like Gender is crucial; radio buttons must be grouped (using a `ButtonGroup` object) to enforce the constraint that only one option can be selected at a time.
➡️ The importance of database connectivity is highlighted for the next session, noting that connecting a project to a database is a common and important topic in technical interviews.
➡️ Import management is critical, especially for external components like the calendar chooser; ensure necessary Java packages are imported correctly before use.
