Implementation

  • Code represents a simple currency converter application using Java Swing for the graphical user interface (GUI). Here's a general explanation of the code:
    • The code includes the necessary import statements for the required classes and packages.
    • The Converter class extends the JFrame class, which represents the main window of the application.
    • Inside the Converter class, there are various components defined as private member variables, including the content pane, text fields for currency rate and amount, a label for displaying the converted result, and strings for storing the currency rate and amount.
    • The constructor of the Converter class sets up the GUI window. It configures the frame title, icon image, size, and close operation. It creates a content pane, sets its layout to null, and adds various components to it (labels, text fields, buttons, and a result label).
    • Two buttons are created: USD-To-KRW and KRW-To-USD. These buttons have associated action listeners that respond when they are clicked. The action listeners retrieve the currency rate and amount entered by the user, create an instance of the ConverterMethod class, and call the appropriate methods to perform the currency conversion. The result is then displayed in the lbDisplay label.
    • The ConverterMethod class is not provided in the given code, so its implementation is missing. However, it can be assumed that this class handles the actual currency conversion calculations.
    • The Main class contains the main method, which is the entry point of the program. It creates an instance of the Converter class and makes it visible by invoking the setVisible(true) method.
