How many classes are there in AWT?
The AWT provides nine basic non-container component classes from which a user interface may be constructed. (Of course, new component classes may be derived from any of these or from class Component itself.) These nine classes are class Button, Canvas, Checkbox, Choice, Label, List, Scrollbar, TextArea, and TextField.
What is meant by AWT?
Abstract Window Toolkit (AWT) is a set of application program interfaces ( API s) used by Java programmers to create graphical user interface ( GUI ) objects, such as buttons, scroll bars, and windows.
What is AWT class hierarchy in Java?
The Java AWT (Abstract Windowing Toolkit) contains the fundamental classes used for constructing GUIs. The JComponent class is derived from Container and is one of the base classes of Swing. The JFrame class is derived from the AWT Frame class. It is usually the main container for a GUI application.
What is AWT list in Java?
The List is a GUI component used to display a list of text items. It contains a set of String values that the user can choose from. It is a ‘list’ that allows the user to select one or more options.
Is Java AWT a class?
The Abstract Window Toolkit (AWT) is Java’s original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing. The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program.
Which is better AWT or Swing?
AWT is a thin layer of code on top of the OS, whereas Swing is much larger. Swing also has very much richer functionality. Using AWT, you have to implement a lot of things yourself, while Swing has them built in. For GUI-intensive work, AWT feels very primitive to work with compared to Swing.
What does AWT stands for MCQ?

- Checkboxes (java. awt.
- Radio Buttons (java. awt.
- Choice Buttons (java. awt.
- Labels (java. awt.
- TextFields (java.awt.TextField) Are areas where the user can enter text.

What is Swing and AWT in Java?
Java AWT is an API to develop GUI applications in Java. Swing is a part of Java Foundation Classes and is used to create various applications.
What is AWT class explain methods of AWT class in java with example?
AWT is heavy weight i.e. its components are using the resources of underlying operating system (OS). The java.awt package provides classes for AWT API such as TextField, Label, TextArea, RadioButton, CheckBox, Choice, List etc.
What is AWT controls java?
Java AWT controls are the controls that are used to design graphical user interfaces or web applications. To make an effective GUI, Java provides java.
Why AWT is heavyweight?
AWT is said to be “Heavyweight” because basically each AWT component is a native platform component. AWT is implemented on top of the platform’s native GUI toolkit. This also explains why AWT was pretty limited compared to Swing.
What are the classes for AWT in Java?
The classes for AWT are provided by the Java.awt package for various AWT components. The following image represents the hierarchy for Java AWT. The component class stands at the top of the AWT hierarchy, is an abstract class that contains all the properties of the component visible on the screen.
What is a component in AWT?

What is the AWT hierarchy?
Following is AWT hierarchy: The Container is one of the components in AWT that contains other components like buttons, text fields, labels, etc. The classes that extend Container class are known as containers such as Frame, Dialog, and Panel as shown in the hierarchy.
What is AWT (Abstract Window Toolkit)?
Java AWT (Abstract Window Toolkit) is an API to develop Graphical User Interface (GUI) or windows-based applications in Java. Java AWT components are platform-dependent i.e. components are displayed according to the view of operating system. AWT is heavy weight i.e. its components are using the resources of underlying operating system (OS).
