Event Handling

This guide explains how to set up, build, and run the project on your local machine.

1. Prerequisites

Before you begin, ensure you have the following installed:

Java Development Kit (JDK): Version 8 or higher is required for Swing components.

NetBeans IDE: It is highly recommended to use NetBeans for the development of the code.

1.1 Clone the Repository

Open your terminal or command prompt and run:

git clone https://github.com/Software-Development-Methodologies/Event-Handling.git
cd Event-Handling/src

2. Setup and Execution

  1. Open Project: Launch NetBeans and open the project directory containing the Exercise 4 source files.
  2. External Documentation: For additional information on how specific classes work, refer to the official Oracle documentation.
  3. Build: Right-click the project and select Build.
  4. Run: Press F6 or click the Run Project button.

3. Core Functionality

The application focuses on the following cognitive subjects:

  • Event Management: Handling user interactions.
  • Listener Interfaces: Using ActionListener for buttons and WindowListener for frame control.
  • Adapter Classes: Implementing window closing events efficiently.

4. Key Implementation Steps

  • Conversion: Use Integer.parseInt(String) to convert input from TextFields into integers.
  • Validation: Before executing operations, check that fields are filled and contain valid integers.
  • Error Handling: If validation fails, display an appropriate error message in the application's Label.

5. Implementation Details

  • Recommended IDE: NetBeans.
  • Window Management: Handle the window close (x) event appropriately depending on the specific frame used.
  • User Input: Text fields return String; convert to integers using Integer.parseInt() for arithmetic operations.
