Write a Java applet that demonstrates the behavior of a FlowLayout by demonstrating some buttons. The program should have a main method to execute the applet
import java.awt.Button;
import java.awt.FlowLayout;
imporjava.awt.Frame;
public class FlowLayouttest extends Frame
{
public FlowLayouttest()
{
setLayout(new FlowLayout()); add(new Button("First"));
add(new Button("Second")); add(new Button("Third"));
add(new Button("Fourth")); add(new Button("Fifth")) ;
setSize(200,200);
}
public static void rnain(String a())
{
new FlowLayouttest().setVisible(true);
import java.awt.FlowLayout;
imporjava.awt.Frame;
public class FlowLayouttest extends Frame
{
public FlowLayouttest()
{
setLayout(new FlowLayout()); add(new Button("First"));
add(new Button("Second")); add(new Button("Third"));
add(new Button("Fourth")); add(new Button("Fifth")) ;
setSize(200,200);
}
public static void rnain(String a())
{
new FlowLayouttest().setVisible(true);
}
}
}
A java applet shows how to create a text-area, a radio-button, a ordinary button.
Solution:
import java.applet.Applet;
import java.awt.Button;
import java.awt.Checkbox;
import java.awt.CheckboxGroup;
import java.awt.TextField;
public class GuiApplet extends Applet
{
Button okButton;
TextField nameField;
CheckboxGroup radioGroup;
Checkbox radiol;
Checkbox radio2;
Checkbox option;
public void init()
{
setLayout(null);
okButton = new Button("A button");
nameField = new TextField("A TextField", 100) ,
radioGroup = new CheckboxGroup();
radiol= new Checkbox("Radiol", radioGroup,false);
radio2= new Checkbox("Radio2", radioGroup,true);
option= new Checkbox("Option",false);
okButton.setBounds(20,20,100,30);
nameField.setBounds(20,70,100,40);

radio2.setBounds(140,120,100,30); option.setBounds(20, 170,100,30) ; add(okButton);
add(nameField);
add(radiol);
add(radio2);
