Java Reading Text Inside File

Question

![enter image description here][1]I have a file called notes.txt containing several lines of text that I want show to my JPanel.

Here is my code:

private void loadNotes() {
    File file = new File("notes.txt");
    if (file.exists()) {
        try {
            FileInputStream fs = new FileInputStream(file);
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(fs));

            for (int i = 0; i < notes.length; i++) {
                if (br.readLine() != null) {
                    String note = br.readLine();
                    System.out.println(note);
                    notes[i] = new JCheckBox(note, false);
                    panel.add(notes[i]);
                    panel.revalidate();
                    panel.repaint();
                }
            }
            br.close();

        } catch (Exception e1) {
        }
    } else {
        System.out.println("File does not exist");
    }
}
            br.close();

This method grabs the lines from the file and prints out the check boxes. So if I have 4 notes then it prints out 4 checkboxes. However, it doesn't print out the text? Why not?

Would like to see more of your code.

You're calling br.readLine() twice in the for loop so every second line of the file will be skipped. Assign the note variable at the start of the loop

String note;
for (int i = 0; i < notes.length; i++) {
    if ((note = br.readLine()) != null) {
        ...
    }
}

i.sstatic.net/YVX8Y.png My result. I removed the if (bt.readLine() != null) correct? I just want each line to print out.... -.-

What does the input file look like?

No spaces, no extra boxes. So aggravating Input file: i.sstatic.net/SDtMm.png

Couldnt have known that, kinda important to post an SSCCE to help us diagnose such issues :)
