Exploring the Java Swing Stock Management System

This comprehensive Java code orchestrates a Stock Management System using Java Swing for GUI components. The StockView class extends JFrame and builds a table for displaying stock data. It features functionalities to add stocks dynamically and save the information to a file (stocks.txt). The StockController class manages the interaction between the view and stock data, reading from a file to populate the initial view. The Stock class defines the structure of a stock, encapsulating essential details. Altogether, this code creates an interactive GUI application for managing stock data, seamlessly integrating UI elements, file handling, and dynamic data updates.

Java Stock Management System GUI: Code Breakdown

This Java Swing Stock Management System serves as a robust foundation for handling and displaying stock data in a graphical interface. The StockView class leverages Java Swing components to create an intuitive table, enabling users to dynamically add stocks and save the information to a file. The StockController facilitates seamless communication between the view and data, efficiently reading and populating the view with stock information from a file. The Stock class encapsulates the essential attributes of a stock. Whether you're learning Java or need help with your Java assignment, this code offers a practical example of GUI development, file handling, and object-oriented programming principles, contributing to a comprehensive understanding of Java applications.

Block 1: Import Statements

• Import necessary Java Swing, AWT, and I/O classes for GUI development, event handling, and file operations.

Block 2: StockView Class

public class StockView extends JFrame { private JTable table; private DefaultTableModel model;

• The StockView class extends JFrame and initializes components like JTable and DefaultTableModel for displaying stock data.

Block 3: StockView Constructor

public class StockView extends JFrame { private JTable table; private DefaultTableModel model;

• Constructor initializes the model with columns for Ticker, Name, and Price.

Block 4: Table Initialization

table = new JTable(model); table.setPreferredScrollableViewportSize(new Dimension(400, 200)); JScrollPane scrollPane = new JScrollPane(table);

• Initializes the JTable, sets its preferred size, and wraps it with a JScrollPane.

Block 5: Button Initialization and Listeners

JButton addButton = new JButton("Add Stocks"); JButton saveButton = new JButton("Save Stocks"); addButton.addActionListener(new ActionListener() { // Add stock button listener }); saveButton.addActionListener(new ActionListener() { // Save stock button listener });

• Creates "Add Stocks" and "Save Stocks" buttons and adds action listeners to handle button clicks.

Block 6: Add Button Listener

public void actionPerformed(ActionEvent e) { // Prompt user for stock information and add to the table }

• When the "Add Stocks" button is clicked, prompts the user for stock information and adds a new row to the table.

Block 7: Save Button Listener

public void actionPerformed(ActionEvent e) { // Save stock information to the "stocks.txt" file }

• When the "Save Stocks" button is clicked, saves the stock information from the table to a file (stocks.txt)

Block 8: Button Panel and Layout

JPanel buttonPanel = new JPanel(); buttonPanel.add(addButton); buttonPanel.add(saveButton); add(scrollPane, BorderLayout.CENTER); add(buttonPanel, BorderLayout.SOUTH);

• Creates a panel for buttons, adds buttons to it, and sets up the layout with the table and button panel.

Block 9: File Writing in Save Button Listener

// File writing logic } catch (IOException exception) { // Exception handling

• Inside the "Save Stocks" button listener, writes stock information to the file (stocks.txt) and handles potential IO exceptions.

Block 10: Stock Class

public class Stock { // Stock class definition

• Defines the Stock class with attributes for Ticker, Name, and Price along with getter and setter methods.

Block 11: StockController Class

public class StockController { private StockView view; public StockController(StockView view) { // Controller constructor }

• Defines the StockController class, taking a StockView as a parameter in the constructor.

Block 12: Reading Stocks from File in StockController

// Reading stocks from file and adding to view } catch (IOException e) { // Exception handling }

• In the StockController constructor, reads stocks from the file (stocks.txt) and adds them to the view using the addStock method.
