Java AWT Package Example

In this section you will learn about the AWT package of the Java. Many running examples are provided that will help you master AWT package. Example provided are supported with tested code.

1. Graphical User Interfaces
   A class library is provided by the Java programming language which is known as Abstract Window Toolkit (AWT).  
   
2. What is AWT in java
   In this section, you will learn about the java.awt.*; package available with JDK. AWT stands for Abstract Windowing Toolkit.
   
3. Describe the AWT Components
   In this section you will learn about the different components available in the Java AWT package for developing user interface for your program.
   

4. AWT Components
   The class component is extended by all the AWT components. More of the codes can be put to this class to design lot of AWT components. Following are the AWT components:
   

   1. Canvas
   2. Checkbox
   3. Label
   4. Scrollbar
   5. TextField
      

5. Common Component Methods
   The common methods of AWT components are as follow:

6. Containers
   As discussed earlier a container is a component that can be nested. The most widely used Panel is the Class Panel which can be extended further to partition GUIs.

7. Describe different types of event to provide by the AWT Components in java
    There are many types of events that are generated by your AWT Application. These events are used to make the application more effective and efficient. Generally, there are twelve types of event are used in Java AWT.

8. Events
   In this section, you will learn how to handle events in Java awt. Events are the integral part of the java platform.

9. Event Adapters
   There are some event listeners that have multiple methods to implement. That is some of the listener interfaces contain more than one method. 

10. Button Pressing Example
    In the program code given below, the Frame contains three buttons named - "Bonjour", "Good Day", "Aurevoir".

11. Adapters Example
    In the following program code, the adapter class has been used. This class has been used as an anonymous inner class to draw a rectangle within an applet.

12. GUI-based Applications
    In this section you will learn about how to create a window for your application. You need to define a subclass of Frame to create a window for your application.

13. Menus
    We can also develop an application with a Menu. As a name indicates a Menu consists of Menu objects.

14. Menu Shortcuts
    The MenuItem class also provides a feature of menu shortcuts and speed keys.
    

15. Pop-up Menus
    A PopupMenu is similar to a Menu as it contains MenuItem objects. The Pop-up Menu can be popped over any component while generating the appropriate mouse event rather than letting it appear at the top of a Frame. 

16. Creating a Frame
    This program shows you how to create a frame in java AWT package. The frame in java works like the main window where your components (controls) are added to develop a application. In the Java AWT, top-level windows are represented by the Frame class.

25. Handling Mouse Clicks
    In this section, you will learn about handling the mouse click event in the awt application.
      
26. Handling Action Events
    In this section, you will learn how to handle events in java awt. Here, this is done through the java.awt.*; package of java. Events are the integral part of the java platform.
      
27. Handling Key Presses
    In this section, you will learn about the handling key press event in java. Key Press is the event is generated when you press any key to the specific component.
      
28. Item Events
    In this section, you will learn about handling item events in java. This demonstrates that the event generated when you select an item from the group of the items.
     
29. How to use KeyListener 
    In this section, you will learn how to handle different key events on the Java Awt component by using the event handling in Java. When the given program is executed then you will see the several key events these are applied on the component like the key pressed, key release and so on.
      
30. Simple Form in Java
    This is a simple program of java awt package which constructs a look like a form by using various java component. In this section, you will learn how to create it. This is done by using java gui programming using Classes or APIs of java awt package.
