What is meant by controls and what are different types of controls in AWT?-

by

Controls are components that allow a user to interact with your application and the AWT supports the following types of controls: Labels, Push Buttons, Check Boxes, Choice Lists, Lists, Scrollbars, Text Components. These controls are subclasses of Component.

In the context of Core Java and AWT (Abstract Window Toolkit), “controls” typically refer to user interface components or widgets that allow users to interact with a graphical user interface (GUI). AWT is a part of Java’s standard library that provides a set of tools for creating graphical user interfaces.

Different types of controls in AWT are often referred to as components. Here are some common AWT components:

  1. Button: A button is a control that the user can click to trigger an action.
  2. Label: A label is a non-editable text component used to display information.
  3. TextField: It provides a single-line input field for the user to enter text.
  4. TextArea: It provides a multi-line text input area.
  5. Checkbox: A checkbox allows the user to select or deselect a particular option.
  6. RadioButton: Radio buttons are used in groups where only one option can be selected at a time.
  7. Choice: A choice is a drop-down menu that allows the user to select one item from a list of options.
  8. List: A list allows the user to select one or more items from a scrolling list.
  9. Scrollbar: Scrollbars are used to navigate through content that doesn’t fit in the visible area.
  10. Panel: A panel is a container that can hold other components.

These components provide the building blocks for creating GUI applications in Java using AWT. Note that Swing, another GUI toolkit in Java, is often preferred over AWT for its richer set of components and improved features.
