Java JList and JTextArea - jlist

Question

I am stuck on a java project.
I am working with TXT files, and i have the open these TXT files from the JList.
Since i am a total noob at this, it took me a few hours to manage to make the JList work. But now i am stuck at the JTextArea.
The idea is this: clicking on a item from the JList (item = a TXT file from a folder), it should open that TXT file in the JTextArea to view it.
..here is my code so far ..it's a bit long:
-JButton for the search and putting the TXT files in the JList:
JButton searchSearchButton = new JButton("Search");
searchSearchButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
DefaultListModel model1 = new DefaultListModel();
File dir = new File("C:\\Users\\Zoli\\Desktop\\New folder");
File[] matches = dir.listFiles(new FilenameFilter() {
public boolean accept(File dir, String name) {
return name.startsWith(searchKeywordTextField.getText()) && name.endsWith(".txt");
}
});
for(File f : matches){
model1.addElement(f.getName());
}
searchList.setModel(model1);
}
});
searchSearchButton.setBounds(186, 43, 89, 23);
linuxSearchPane.add(searchSearchButton);
-This is the JTextArea and the JList code:
final JTextArea searchTextArea = new JTextArea();
JScrollPane searchTextAreaScrollPane = new JScrollPane(searchTextArea);
searchTextAreaScrollPane.setBounds(316, 43, 496, 430);
linuxSearchPane.add(searchTextAreaScrollPane);
final JList searchList = new JList();
searchList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
searchList.setVisibleRowCount(20);
searchList.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
searchTextArea.setText("");
for(Object o : searchList.getSelectedValuesList()){
searchTextArea.append(o.toString()+"\r\n");
}
}
});
-All i managed to do is, when i select an item from the JList, it prints out the item name in the JTextArea not what it contains in the TXT.
Here is a picture to show you:

Answer 1

I DID IT!!!
Here's the code:
final JTextArea searchTextArea = new JTextArea();
JScrollPane searchTextAreaScrollPane = new JScrollPane(searchTextArea);
searchTextAreaScrollPane.setBounds(316, 43, 496, 430);
linuxSearchPane.add(searchTextAreaScrollPane);
final JList searchList = new JList();
searchList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
searchList.setVisibleRowCount(20);
searchList.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
searchTextArea.setText("");
String root = "C:\\Users\\Zoli\\Desktop\\New folder\\";
String filename;
String lineRead = "";
String fileContent = "";
try {
for(Object o : searchList.getSelectedValuesList()){
filename = o.toString();
FileReader reader = new FileReader(root + filename);
BufferedReader buffer = new BufferedReader(reader);
while(lineRead != null){
try {
lineRead = buffer.readLine();
} catch (IOException e1) {
e1.printStackTrace();
}
if(lineRead != null){
fileContent = fileContent + lineRead + "\r\n";
searchTextArea.setText(fileContent);
}
}
}
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
});
Also here's the picture to see how it works: picture
