    <p>This project I'm working on, here is the function which write data's in to file :</p> <pre><code> public void writetofile(){ String bucky[]={custname,custlname,agee,address,id}; for(int i = 0; i &lt; bucky.length; i++) { try (BufferedWriter bw = new BufferedWriter(new FileWriter("records.txt", true))) { String s; s = bucky[i]; bw.write(s); bw.newLine(); bw.flush(); } catch(IOException ex) { JOptionPane.showMessageDialog(null, "Error In File"); } } }; </code></pre> <p>and there is another function defined which reads data's from file , </p> <pre><code> public void filereader (){ int i=0; Object[] options = {"OK"}; try { FileInputStream in = new FileInputStream("records.txt"); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; StringBuffer sb = new StringBuffer(); while((strLine = br.readLine())!= null) { sb.append(strLine +"\n"); } JOptionPane.showMessageDialog( null, sb.toString()); }catch(Exception e){ JOptionPane.showOptionDialog(null, "Error", "Customers", JOptionPane.PLAIN_MESSAGE,JOptionPane.QUESTION_MESSAGE, null, options, options[0]); } }; </code></pre> <p>and the problem is , let's say I want to create an account for a customer in my project , so few questions were asked such as name , last name , gender , etc. and all those info's have been saved , but when I try to read files all the data's will appear in no format , I want them to be appear in the proper way like this : </p> <pre><code>customer name : Michelle , gender : Female ; </code></pre> <p>but right now it appears as this : </p> <pre><code>michelle , female , </code></pre>

    1. COThat's how data will be stored in a file. You can create a class which has all these fields and after reading each line from your file, you can split it and populate an object of that class and add it to a list. Keep repeating this till you've read the whole file. And then you can override the `toString()` method in your class which will print the data in the format you want! :)

    2. COYou need to change your writer to support the format that you want. You could also consider using XML or even a light weight database

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.
