What are listeners and how it is used in event handling?
Listeners are java classes which extend EventListener. Event handling is a process of notifying listeners of an event. For example if you click a button, the AWT thread will process the click and the button will notify any of it's relevant listeners of the event that just occurred, calling all the added ActionListeners actionPerformed functions. When events happen the system doesn't know who to tell about the actions. Telling everybody would be a waste. So listeners are required to be registered to the various Swing and AWT classes, as well as any custom listeners you may want to write, so as to know who should be told when something happens. Which is how the listener paradigm works thus implementing event handling (at least in Java).
What are Awt Components?
AWT stands for Abstract window tootlkit . Abstract window Toolkit provides a standard application programming interface for writing graphical user interfaces in java.
Which are the AWT components in Java?
AWT stands for Abstract window toolkit. AWT gives us the components using which we can create User- Interface based applications in java. Some of the components are: a. Frame b. Panel c. Window d. CheckBox e. RadioButton f. Button g. TextBox h. TextArea i. Etc
What is abstract windowing toolkit?
The Abstract Window Toolkit (AWT) supports Graphical User Interface (GUI) programming. AWT features include: * a rich set of user interface components; * a robust event-handling model; * graphics and imaging tools, including shape, color, and font classes; * layout managers, for flexible window layouts that don't depend on a particular window size or screen resolution; * data transfer classes, for cut-and-paste through the native platform clipboard.
What is awt in java?
java.awt is a standard package of Java. It is a GUI(Graphical User Interface) package, which has classes in it such as Frame, Panel, and Button. Most of the package was later replaced with the javax.swing package, which has most of the same classes, only with a J prepended to them (JFrame, JPanel, JButton). However the java.awt package still includes some event handlers that are considered standard in java (java.awt.event).

What is swing and swing event?
Swing is the api defined in javax.swing package and used to add graphical interface to the user by providing controls like JButton , JLabel , JTextField etc. if there is a User Interface then there has to be a way to handle the events generated by these controls so event is the general interaction of the user and the application which can be delegated using any delegation model..simple examples of the events are MouseEvent (click, double click etc.) swing is also known as JFC (java foundation classes) before using swing for designing user interface we were using awt which are heavy objects as compared to swing objects and swing has a better look and feel also.

What is the methods with the parameters of an AWT?
