Java Image Query Problem

Hello. I am posting here, as I am having a problem, maybe more. What I am trying to do is to emulate a Google Image Search.
I found a way to do this by using no special APIs as I am completely unfamiliar to this kind of practice. What I am trying to do in order to grab an image query
is this:
Append my query term to the following link:

http://ajax.googleapis.com/ajax/serv...mages?v=1.0&q=

You can see the actual page here:
http://ajax.googleapis.com/ajax/serv...?v=1.0&q=panda
This will return a result like:

Code:

for Querying the term "panda"

The Result itself might seem confusing at first, but by filtering it with the following regex a much more clear list of results can be displayed.

(\"http\\S+?jpg\")

After applying this regex a list like the following can be extracted:

As you can easily tell, not all URLs are valid, but there are 2 or 3 that could be used.
What I am trying to do is extracting a list of "potential valid URLs" and then try to make labels with imageIcons extracted off the valid links.
This is my code so far.

Code:

import java.awt.BorderLayout; public class browser extends JFrame { private JPanel contentPane; private JTextField textField; /** * Create the frame. */ public browser() { setBounds(100, 100, 450, 300); setVisible(true); contentPane = new JPanel(); contentPane.setBorder(new EmptyBorder(5, 5, 5, 5)); setContentPane(contentPane); contentPane.setLayout(null); textField = new JTextField(); textField.setBounds(6, 11, 390, 28); contentPane.add(textField); textField.setColumns(10); mainFrame mOb = new mainFrame(); JButton search = new JButton(""); search.setIcon(new ImageIcon("C:\\Users\\Mihai\\Desktop\\search-icon.png")); search.setBounds(397, 11, 31, 28); contentPane.add(search); JScrollPane scrollPane = new JScrollPane(); scrollPane.setBounds(6, 51, 422, 205); contentPane.add(scrollPane); scrollPane.getViewport().setOpaque(false); final JPanel editorPane = new JPanel(); scrollPane.setViewportView(editorPane); editorPane.setOpaque(false); editorPane.setBackground(new Color(0,0,0,0)); JLabel background = new JLabel(""); background.setBounds(0, 0, 434, 262); contentPane.add(background); background.setIcon(mOb.BG); final JEditorPane editorPane_1 = new JEditorPane(); editorPane_1.setBounds(6, 35, 0, 0); contentPane.add(editorPane_1); editorPane.setLayout(new FlowLayout()); //SEARCH LISTENER search.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { String query = textField.getText(); // VALID SEARCH if(query!=""){ String rawString=""; try{ URL rawURL = new URL("http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q="+query); editorPane_1.setPage(rawURL); rawString = editorPane_1.getText().replaceAll("\n", System.getProperty("line.separator")); editorPane_1.setText(""); System.out.println(rawString); }catch(Exception ex){ ex.printStackTrace(); System.out.println("FIRST BLOCK "); } //GET NUMBER OF LINKS Pattern pattern = Pattern.compile("(\"http\\S+?jpg\")"); Matcher matcher = pattern.matcher(rawString); int j = 0; while (matcher.find()) { j++; } String refString[] = new String[j]; //ASSIGN LINKS Pattern pattern2 = Pattern.compile("(\"http\\S+?jpg\")"); Matcher matcher2 = pattern.matcher(rawString); int k =0; while (matcher2.find()) { refString[k]=matcher2.group().toString(); System.out.println(refString[k]); } //INSERT PROPER REGEX int i = 0; for(i = 0; i<refString.length; i++){ JLabel label= new JLabel("SUP"); label.setPreferredSize(new Dimension(200,100)); try{ URL url = new URL(refString[i].trim()); ImageIcon icon = new ImageIcon(ImageIO.read(url)); label.setIcon(icon); }catch(Exception ex){ ex.printStackTrace(); continue; } System.out.println("\n FINISHED BLOCK!!!!

//I have deleted one of the exceptions as i should limit myself to 20000 characters per post, but it's essentially the same as the other null-pointers

The first line is the raw query, the nest 6 are "potentially valid URLs" and the code following is a series of exceptions. You can observe that The first exception refers to a malformed URL exception, while all the others refer to null-pointer exceptions.

I am curious and seeking help about the following:

•Why is the sequence of exceptions like it is?
•Can you help me design a better RegEx to grab valid URLs?
•Is there a better, and not very complicated way of doing the same thing(making an image query) without all this trouble?

Thank you so much for your time!
