For this homework, you are to create a simple Swing application that implements an event-driven programming concept. Problem Statement: Create a Swing application that represents a simple calculator. The calculator should have a text field for the display and buttons for the digits 0-9, the four basic arithmetic operations (+,-..^). and an equals (=) button. Steps: 1. Create a new JFrame object. Set its size to 400 by 400 pixels and set the layout manager to null or GridLayout based on your design preference. Also, use the setDefaultCloseOperation method to ensure the application exits when the window is closed. 2. Create JButton objects for each digit, operation, and the equals button. Set the bounds of the buttons using the setBounds method or let the layout manager handle it. 3. Add an ActionListener to each button. Inside the actionPerformed method (which is called when a button is clicked), perform the appropriate action. For the digit buttons, this should add the digit to the current number in the display. For the operation buttons, this should store the current number and the operation for later. The equals button should perform the stored operation on the stored number and the current number, then display the result. 4. Add the buttons and the text field to the frame using the add method. Finally, make the frame visible using the setVisible method. For this homework, you are to create a simple Swing application that implements an event-driven programming concept.
