URL Source Code Generator in Java with Source Code

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

1. URL u=new URL("https://www.facebook.com");//change the URL  
2. URLConnection uc=u.openConnection();  
3. InputStream is=uc.getInputStream();  
4. int i;  
5. StringBuilder sb=new StringBuilder();  
6. while((i=is.read())!=-1){  
7.     sb.append((char)i);  
8. }  
9. String source=sb.toString();  

Let's see the swing code to generate Source Code of URL.

1. import java.awt.*;  
2. import java.awt.event.*;  
3. import java.io.InputStream;  
4. import java.net.*;  
5. public class SourceGetter extends Frame implements ActionListener{  
6.     TextField tf;  
7.     TextArea ta;  
8.     Button b;  
9.     Label l;  
10.     SourceGetter(){  
11.         super("Source Getter Tool - Javatpoint");  
12.         l=new Label("Enter URL:");  
13.         l.setBounds(50,50,50,20);  
14.           
15.         tf=new TextField();  
16.         tf.setBounds(120,50,250,20);  
17.           
18.         b=new Button("Get Source Code");  
19.         b.setBounds(120, 100,120,30);  
20.         b.addActionListener(this);  
21.           
22.         ta=new TextArea();  
23.         ta.setBounds(120,150,250,150);  
24.           
25.         add(l);add(tf);add(b);add(ta);  
26.         setSize(400,400);  
27.         setLayout(null);  
28.         setVisible(true);  
29.     }  
30.     public void actionPerformed(ActionEvent e){  
31.         String s=tf.getText();  
32.         if(s==null){}  
33.         else{  
34.             try{  
35.             URL u=new URL(s);  
36.             URLConnection uc=u.openConnection();  
37.           
38.             InputStream is=uc.getInputStream();  
39.             int i;  
40.             StringBuilder sb=new StringBuilder();  
41.             while((i=is.read())!=-1){  
42.                 sb.append((char)i);  
43.             }  
44.             String source=sb.toString();  
45.             ta.setText(source);  
46.             }catch(Exception ex){System.out.println(e);}  
47.         }  
48.     }  
49.     public static void main(String[] args) {  
50.         new SourceGetter();  
51.     }  
52. }
