AWT

AWT Stands for Abstract Window Toolkit. 

It is an API.

It is used to create graphical user interface/ tools.

How to include library for using awt- 

import java.awt.*; 

* includes all functions and utilities under awt library.

Inherites the Frame to your driver class/ main class- 

class first extends Frame
{ 
// Name of class is first
}

Use of constructor- (inside the driver class)

class first extends Frame
{
first() 
{ 

}
}

Creating Frame -

We need to create Frame inorder to create tools.

Firstly, Frame is created inside it we create tools.  


class first extends Frame
{ 
first() 
 { 
 setSize(400,400); 
 setLayout(null); 
 setVisible(true); 
  }  
}

Here creates 3 functions inside the constructor - 

1.setSize(height,width); 

2.setLayout(null); 

3.setVisible(true);  


Call the Constructor- (in the main method)

class first extends Frame
{ 
first() 
 { 
 setSize(400,400); 
 setLayout(null); 
 setVisible(true); 
  }  
public static void main(String args[]) 
{ 
first F1= new first(); 
//Here the constructor will be implicitly called.
} 
}

Creating button control

Frame Creation-  Frame can be created using two methods-  1. Inherites Frame class.  2. Create the object of Frame class.  Here we will create button using Frame(through second method)-  import java.awt.*;  class first  {  first()  {  //Create an object of Frame  Frame F1= new Frame();  //Create an object of button Button b1= new Button ("click me");   // Set the attribute of button //setBounds (left,top,width,height); b1.setBounds(50,80,80,80);   //add() is used to add the button control to Frame F1.add(b1);  //Call the functions using Frame's object F1.setSize(400,400);  F1.setLayout(null);  F1.setVisible(true);   }  public static void main(String args[])  {  first Fst1= new first();  }  }
