what is difference between Component And Object

A component is an object having a graphical representation that can be displayed on the screen and that can interact with the user.

Examples of components are the buttons, checkboxes, and scrollbars of a typical graphical user interface.

The Component class is the abstract super class of the non menu-related Abstract Window Toolkit components. Class Component can also be extended directly to create a lightweight component. A lightweight component is a component that is not associated with a native opaque window.

Hi!
Object is entity of class like real world, but component is the graphical class that is displayed on the screen and helpful to use to intract with a user.
