How to Acquire Button Source in AWT for Calculator Project
In your calculator homework, you encountered a challenge where you needed to obtain the value of each button numerically pressed. To achieve this, consider the following approach:
Instead of relying on the getSource() method, which only provides you with the physical object reference, shift your focus to detecting user input by registering action listeners for each button. Each time a button is clicked, the corresponding action listener will be triggered, providing you with valuable information about the event, including the source (the button that was clicked) and relevant details about the operation being performed.
By accessing the button that generated the event and extracting its text value, you can obtain the numerical value of each button pressed. This approach aligns more effectively with the task at hand and offers a more direct solution for retrieving the desired information.
