The application accepts user inputs for height (in centimeters) and weight (in kilograms), then calculates and displays the BMI value along with the corresponding health category classification.

✨ Features

  • Simple GUI Interface: Clean and intuitive Swing-based user interface
  • Real-time Calculation: Instant BMI calculation upon button click
  • Health Category Classification: Displays BMI category (Underweight, Normal, Overweight, Obese)
  • Input Validation: Ensures valid numeric inputs for accurate calculations
  • Cross-platform: Runs on any platform with Java installed (Windows, macOS, Linux)

🛠️ Technologies Used

  • Java: Core programming language
  • Swing: GUI framework for desktop interface
  • AWT: Abstract Window Toolkit for UI components
