    <p>Hello i have coded an application to write something from a TextArea into a text document but the problem is,he does write it,but it dosen't store it and when i open it again,to write more in the same text document(or create a new document). How could i do that ? And a aditional information that i would require is how can i add date stamp alonside the text i enter in text document? Here is my code : </p> <pre><code>import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextArea; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.FileWriter; import java.io.IOException; public class Write extends JFrame { JTextArea text; public Write() { this.setTitle("Writerz!"); setSize(400, 200); setResizable(false); setLocation(370, 150); setLayout(null); JLabel lbltitlu = new JLabel("Insert your text here"); lbltitlu.setBounds(85, 5, 120, 25); this.add(lbltitlu); final JTextArea text = new JTextArea(); text.setSize(199, 199); text.setBounds(85, 65, 120, 25); add(text); JButton btn = new JButton("Add text"); btn.setSize(99, 99); btn.setBounds(125, 125, 120, 25); add(btn); ActionListener listenerbtn = new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { // TODO auto- generated method String actionbtn = arg0.getActionCommand(); if (actionbtn.equals("Add text")) { Adauga(text.getText()); } } }; btn.addActionListener(listenerbtn); } public void Adauga(String text) { String filename = "test.txt"; FileWriter writer = null; try { writer = new FileWriter(filename); writer.write(text); } catch (IOException exception) { System.err.println("Save oops"); } finally { if (writer != null) { try { writer.close(); } catch (IOException exception) { System.err.println("Error closing writer"); exception.printStackTrace(); } } } } } </code></pre> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
