Redirecting output to table in Java Swing



Newbie here, I have a problem, redirecting my output to a Jtable. The data is coming from a different class that does the real work which is Scanner.java.


With this said, Scanner.java could print what i want on console but since I added gui which am still learning I have created a new class MainFrame.java and I want search or scan result form Scanner.java to be populated in my JTable but am finding it hard to get the login.


Scanner.java



public void getCompanyProfile(){
Document sourceCode;

EventQueue.invokeLater(new Runnable() {
public void run() {
try {
List<String> allLinks = results();
Document sourceCode;
int counter = 1;
for (String link : allLinks){
System.out.println("Link #:" + counter + " " + link);
sourceCode = PageVisitor.getHtmlSource(link);
Elements profile = sourceCode.select("div.company a.cd");
for (Element links : profile) {
String linkHref = links.attr("href");
System.out.println(linkHref);
setUserData(linkHref);
}
counter++;
}
} catch (Exception e) {
e.printStackTrace();
}
}
});

}

private void setUserData(String url) throws IOException{
Extractor data = new Extractor();
// Scan each page alibaba initial result
data.setProfile(url);
this.companyName = data.getName();
this.country = data.getCountry();
HashSet<String> webites = data.getSellerUrls();

this.webAndEmail = new HashMap<String, HashSet<String>>();
HashSet<String> emails;

for (String webs: webites){
emails = data.emailExtractor(webs);
webAndEmail.put(webs, emails);
for (String anEmail : emails){
//This is the part i want to be displayed in my JTable Component.
System.out.println("Company=" +companyName + ", country=" + country + ", web="
+ webs + ", email=" + anEmail);
}
}

}

public String getProductName(){
return this.product;
}
public String getSource(){
return this.source;
}
public String getCompanyName(){
return this.companyName;
}
public String getCountry(){
return this.country;
}
public Map<String, HashSet<String>> getWebandEmail(){
return this.webAndEmail;
}


Finally, this is my MainFrame.java file below .



![JButton btnStart = new JButton("Start");
btnStart.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {


}
});
btnStart.setBounds(197, 166, 75, 29);
frame.getContentPane().add(btnStart);



//more statements like the above to establish all col. titles
String\[\] columnNames = {"Company Name", "Email", "Website", "Country", "Product", "Source"};
//Sample data to be printed
Object\[\]\[\] data =
{
{"Code Java Ltd", "bingo@codejava.net", "http://www.codejava.com", "Universe", "Polythecnic", "Ebay - B2B"},

};

DefaultTableModel model = new DefaultTableModel(data, columnNames) {

@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
};



resultTable = new JTable(model);
//resultTable.setBounds(37, 259, 553, 143);
resultTable.getColumnModel().getColumn(0).setPreferredWidth(150);
resultTable.getColumnModel().getColumn(1).setPreferredWidth(150);
resultTable.getColumnModel().getColumn(2).setPreferredWidth(150);
resultTable.getColumnModel().getColumn(3).setPreferredWidth(150);
resultTable.getColumnModel().getColumn(4).setPreferredWidth(100);
resultTable.getColumnModel().getColumn(5).setPreferredWidth(100);

resultTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

JScrollPane scrollPane = new JScrollPane( resultTable );
scrollPane.setBounds(37, 259, 806, 143);
frame.getContentPane().add( scrollPane );
//frame.add(resultTable);

JButton button = new JButton("Stop");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
button.setBounds(289, 166, 75, 29);
frame.getContentPane().add(button);][1]


This is what am trying to attain. My other idea is to write the content to CSV from Scanner.java class file and read the file lated to populate the table. But like I said, am a beginner still don't think it would be that easy. So I kindly need someone to point me in the right direction.
