This project is a comprehensive Home Search Engine application built with Java and the JavaFX framework. It allows users to view a collection of house data, perform various search operations, sort the data, and dynamically add new house properties.
- Data Persistence: The application reads house data from a
home_data.jsonfile on startup and saves any new additions back to the same file. - Dynamic Property Addition: A feature is implemented to allow the user to input details for a new property and add it to the live data set.
- Input Validation: All new property data is validated using methods in
ErrorValidation.javato prevent bad or missing data from being added.
- Input Validation: All new property data is validated using methods in
- Advanced Search Functionality: Users can search the house listings using multiple criteria:
- City/State/Zip
- Number of Bedrooms and Bathrooms
- Minimum and Maximum Price Range
- Square Footage (SqFt)
- Data Sorting: The application provides two different sorting algorithms for house listings based on the property price:
- Bubble Sort
- Merge Sort
- Error Logging: Exceptions encountered during data reading or other processes are logged to an
error_logfile.
