Difference Between Paint And Repaint In Java
In Java, the paint() method is part of the AWT and Swing frameworks and is responsible for rendering graphical components on a GUI. This method is called automatically by the system when a component needs to be painted or displayed. On the other hand, repaint() is a method that is used to request the repainting of a specific component or the entire GUI, triggering the subsequent invocation of the paint() method. By calling repaint(), developers can update the visual appearance of components in response to changes or user interactions without directly invoking the paint() method.

1 - Paint in Java:
The paint() method in Java is used for rendering graphics on a component or container.
It is automatically called by the system whenever the component needs to be repainted, such as when the component is first displayed or when its size changes.
The paint() method is responsible for drawing the appearance of the component based on its current state and properties.
2) Repaint in Java:
The repaint() method in Java is used to request that a component be repainted.
Calling repaint() does not immediately repaint the component; instead, it schedules the component to be repainted at a later time.
This allows for more efficient painting by grouping multiple update requests together.
3) Difference:
The paint() method is responsible for actually drawing the graphics on the component, while the repaint() method is used to schedule the component for repainting.
paint() is implemented by the programmer to define how the component should be visually represented, while repaint() is a system method for triggering the repainting process.
By calling repaint(), the component will be repainted on the screen based on the instructions provided in the overridden paint() method.
4) Training Program:
In our training program, students will learn the fundamental concepts of painting and repainting in Java GUI applications.
Students will understand how to implement the paint() method to customize the visual appearance of components.
They will also learn how to use the repaint() method effectively to update the display of components when needed.
Hands on exercises and projects will be provided to reinforce the understanding of painting and repainting in Java programming.
