When an application or a program keeps on monitoring and quickly responds to any action that occurs at the GUI interface ,like mouse movement, selecting an item in a list or entering a keyboard input and so on then such a scenario is termed as event handling. In java the events from the event sources are captured and they are sent to event listeners for respective actions to be taken.

do all components generate mouse events
No. There is no such keyword as declar in Java.
1.Implement the Listener interface and overrides its methods 2.Register the component with the Listener

When an application or a program keeps on monitoring and quickly responds to any action that occurs at the GUI interface ,like mouse movement, selecting an item in a list or entering a keyboard input and so on then such a scenario is termed as event handling. In java the events from the event sources are captured and they are sent to event listeners for respective actions to be taken.
Java does support Events. An event is a software message that informs an object that a particular action has occurred, such as a mouse click, the window's size being adjusted, or a timer signalling that a period of time has passed.
This refers mainly to events that can happen when programming with a graphical user interface; in Java, this might be programmed with the Swing platform. The idea is to react to different "events", things that can happen, often as a result of user interaction. Such events include mouse actions (mouse click, mouse button pressed, mouse button released, mouse enters a visual object, mouse leaves a visual object), keyboard actions (such as pressing a key), focus changes (an object gets or loses the "focus" or "control" - for example, when you press Tab, you change the active control), and timer events (a certain time has passed). "Event handling" simply means being able to detect, and react to, all of these events.

The main event of "The Lion and the Mouse" is when the mouse helps the lion by freeing him from a hunter's trap. This act of kindness and bravery later leads to the lion sparing the mouse's life when he is in need. It illustrates the importance of showing kindness to others, regardless of their size or stature.
mouse over is an event that you can give to an object to make it so that when the person looking at the website puts the mouse over that object it will preform a task in which you assign it.
