The setBounds(int xaxis, int yaxis, int width, int height) method is used in the above example that sets the
position of the awt button.
AWT Example by Association
Let's see a simple example of AWT where we are creating instance of Frame class. Here, we are showing
Button component on the Frame.
import java.awt.*;
class First extends Frame{
First(){
Button b=new Button("click me");
b.setBounds(30,100,80,30);// setting button position
add(b);//adding button into frame
setSize(300,300);//frame size 300 width and 300 height
setLayout(null);//no layout manager
setVisible(true);//now frame will be visible, by default not visible
}
public static void main(String args[]){
First f=new First();
}}](https://image.slidesharecdn.com/javaawttutorial-javatpoint-181126034935/85/Java-awt-tutorial-javatpoint-3-320.jpg)

Java awt tutorial javatpoint
This document provides an overview of Java AWT (Abstract Window Toolkit), which is an API for developing GUI applications in Java. It discusses key AWT concepts like components, containers, frames and panels. It also provides examples of creating simple AWT applications by extending the Frame class and by instantiating the Frame class. The examples demonstrate how to add buttons to a frame and set the button position and frame size.

Java AWT components are platform-dependent i.e. components are displayed according to the view of operating system. AWT is heavyweight i.e. its components are using the resources of OS. The java.awt package provides classes for AWT api such as TextField, Label, TextArea, RadioButton, CheckBox, Choice, List etc. Java AWT Hierarchy The hierarchy of Java AWT classes are given below. Container The Container is a component in AWT that can contain another components like buttons, textfields, labels etc. The classes that extends Container class are known as container such as Frame, Dialog and Panel.
- 2. 29/9/2017 Java AWTTutorial - javatpoint https://www.javatpoint.com/java-awt 2/4 Window The window is the container that have no borders and menu bars. You must use frame, dialog or another window for creating a window. Panel The Panel is the container that doesn't contain title bar and menu bars. It can have other components like button, textfield etc. Frame The Frame is the container that contain title bar and can have menu bars. It can have other components like button, textfield etc. Useful Methods of Component class Method Description public void add(Component c) inserts a component on this component. public void setSize(int width,int height) sets the size (width and height) of the component. public void setLayout(LayoutManager m) defines the layout manager for the component. public void setVisible(boolean status) changes the visibility of the component, by default false. Java AWT Example To create simple awt example, you need a frame. There are two ways to create a frame in AWT. By extending Frame class (inheritance) By creating the object of Frame class (association) AWT Example by Inheritance Let's see a simple example of AWT where we are inheriting Frame class. Here, we are showing Button component on the Frame.
