1) Basic part of a GUI such as a button, a text field or a label. 2) Type of programming where the program waits for a type of event such as a mouse click or a collision to happen and then responds to it. 3) The class that provides a window on the screen.

This is the default layout manager for JPanels. 7) A layout manager that separates the area into cells based on the specified number of rows and columns and placing one component in each cell of the grid. 8) A component that can be drawn to and that can also contain other components. This component can also have its own layout manager. 9) A method that reduces the window size to the required size needed to fit all components.
