} 

public static void main(String args[])

{

   text1 te1 = new text1();

}

}

2. TextArea-

import java.awt.*;

class text2

    ta1.setBounds(10,30,300,300);

    f1.add(ta1);

  f1.setVisible(true);

}

public static void main(String args[])

{

   text2 ta2 = new text2();

}

}

3. Checkbox-

PROGRAM-

import java.awt.*;

class check

{

check()

{

  Checkbox c1 = new Checkbox("python");

  c1.setBounds(100,100,50,50);

 

  Checkbox c2 = new Checkbox("java");

  

  c2.setBounds(100,150,50,50);

  f1.add(c1);

  f1.add(c2);

  f1.setSize(400,400);

 f1.setLayout(null);

 

 f1.setVisible(true);

} 

 public static void main(String args[])

{

  check ch1 = new check();

}

}

4. Label-

import java.awt.*;

class awt4

{

 awt4()

{

   Frame f1 = new Frame();

   Label l1 = new Label("Enter any number");

    l1.setBounds(50,80,80,80);

   

    f1.add(l1);

   

    f1.setSize(400,400);

    f1.setLayout(null);

    f1.setVisible(true);

 }

public static void main(String args[])

{

    awt4 a1 = new awt4();

}

}

5.Button-

import java.awt.*;

class awt3

{

awt3()

{

  Frame f1=  new Frame();

  Button b1 = new Button("Click here");

 b1.setBounds(50,80,80,80);

 f1.add(b1);

 

 f1.setSize(400,400);

 f1.setLayout(null);

 f1.setVisible(true);

}

public static void main(String args[])

{

  

  awt3 a1 = new awt3();

}

}
