IP Finder in Java with Source Code

IP Finder in Java with Source Code: We can develop IP Finder in java with the help of Networking, AWT/Swing with event handling. Let's see the code of creating IP Finder in java.

1. String url="www.javatpoint.com";  
2. InetAddress ia=InetAddress.getByName(url);  
3. String ip=ia.getHostAddress();  

Let's see the Swing code to find IP address.

1. import javax.swing.*;  
2. import java.awt.event.*;  
3. import java.net.*;  
4. public class IPFinder extends JFrame implements ActionListener{  
5.     JLabel l;  
6.     JTextField tf;  
7.     JButton b;  
8. IPFinder(){  
9.     super("IP Finder Tool - Javatpoint");  
10.     l=new JLabel("Enter URL:");  
11.     l.setBounds(50,70,150,20);;  
12.     tf=new JTextField();  
13.     tf.setBounds(50,100,200,20);  
14.       
15.     b=new JButton("Find IP");  
16.     b.setBounds(50,150,80,30);  
17.     b.addActionListener(this);  
18.     add(l);  
19.     add(tf);  
20.     add(b);  
21.     setSize(300,300);  
22.     setLayout(null);  
23.     setVisible(true);  
24. }  
25. public void actionPerformed(ActionEvent e){  
26.     String url=tf.getText();  
27.     try {  
28.         InetAddress ia=InetAddress.getByName(url);  
29.         String ip=ia.getHostAddress();  
30.         JOptionPane.showMessageDialog(this,ip);  
31.     } catch (UnknownHostException e1) {  
32.         JOptionPane.showMessageDialog(this,e1.toString());  
33.     }  
34. }  
35. public static void main(String[] args) {  
36.     new IPFinder();  
37. }  
38. }
