ProgressBar Application Overview This project is a simple Java Swing application that demonstrates the implementation of a graphical progress bar (JProgressBar). The application displays a progress bar that fills up from 0% to 100% over time, providing a visual representation of progress. This project is ideal for learning about basic Swing components and multi-threading with Thread.sleep().
Features Swing UI: The application uses Java's Swing framework to create a GUI window. Dynamic Progress Bar: A JProgressBar element fills gradually, simulating progress in an application. Custom Styling: Progress bar uses the Consolas font with bold styling. The progress bar text is painted and updates in real-time to display the percentage. Custom foreground color for the progress bar (red in this case). Code Breakdown Main Components: JProgressBar: This is the main component that displays the progress. It starts with an initial value of 50 and gradually progresses to 100%.
Progress Fill Method:
The method Fill() is responsible for incrementing the value of the progress bar from 0 to 100. It pauses for 50ms between increments using Thread.sleep(), simulating progress over time. Customization: Font and Color:
The progress bar uses the Consolas font in bold, with a size of 20 for clear visibility. The progress bar is styled with a red foreground to make the progress stand out. Layout and Dimensions:
The layout is null, allowing precise control over component placement. The progress bar is placed within a window of size 500x500px. Main Class: ProgressBar: Inherits from JFrame to create the main application window. Implements ChangeListener but currently does not handle any change events directly (which can be extended in the future). Requirements Java Version: Ensure you have JDK 8 or above installed.
