create an applet to display the Fibonacci numbers
1)AppletExample.java:
import java.awt.*; import java.applet.*; import java.awt.event.*; public class AppletExample extends Applet implements ActionListener{ TextField text; TextArea area; Label label1,label2; Button button; public void init(){ setLayout(null); label1 = new Label("How many numbers do you want in Series: "); label1.setBounds(20,20,250,20); add(label1); text=new TextField(20); text.setBounds(300,20,100,20); add(text); label2 = new Label("Fibonacci Series: "); label2.setBounds(20,50,250,20); add(label2); area=new TextArea(5,15); area.setBounds(300,50,100,80); add(area); button = new Button("Find"); button.setBounds(300,140,100,20); add(button); button.addActionListener(this); } public void actionPerformed(ActionEvent ae){ StringBuffer buffer=new StringBuffer(); int num = Integer.parseInt(text.getText()); int f1=0,f2=0,f3=1; for(int i=1;i<=num;i++){ buffer.append(f3); buffer.append("\n"); f1=f2; f2=f3; f3=f1+f2; } area.setText(buffer.toString()); } }
2)applet.html:
<HTML> <BODY> <APPLET ALIGN="CENTER" CODE="AppletExample.class" width = "700" height = "400"></APPLET> </BODY> </HTML>
