JLabel set as text list items

Question

I have a list that contains Strings and I am trying to set its items as JLabel text, the only problem is that the result is a single line

JButton btnSearch = new JButton("Search");
btnSearch.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent arg0) {
        String fileName = textField.getText();
        StringBuilder result = new StringBuilder();
        List <String> searchResult = new Search().cautaFisiere("C:\\AdwCleaner", fileName);

        for (int x = 0; x < searchResult.size(); x++) {
            result.append(searchResult.get(x)).append("\n");

        }
        lblNewLabel.setText(result.toString());
    }

});

As you can see I tried appending items as new line but no result. I also tried append(System.getProperty("line.separator")) but still no result, the text is still displayed in one line

Uma Kanth it is not empty, and I can print the results on the label as a single line, but I want them printed as a list — alin dradici, Jan 17 '17 at 16:07

I tried doing it. The result was the same, it just prints in a single line. — hashmap, Jan 17 '17 at 16:11
If you want to display the contents of a file then `JLabel` is the wrong component. Consider using a multi-line text component like `JTextArea` (and use `jtextarea.setEditable(false)` to make it read-only). — Quota, Jan 17 '17 at 16:20
Quota I am trying to display the contents of a list, JTextArea is for text editing — alin dradici, Jan 17 '17 at 16:21
That's what `setEditable(false)` is for. Then you have a perfectly fine component to display text. Works nearly out of the box (don't forget scroll panes--which you'd need for the label, too...). — Quota, Jan 17 '17 at 16:24

As mentioned in here Multiline text in JLabel, just can just use HTML tag <br> to make a new line, but it must be in <html></html> tags.

JButton btnSearch = new JButton("Search");
btnSearch.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent arg0) {
        String fileName = textField.getText();
        StringBuilder result = new StringBuilder();
        List <String> searchResult = new Search().cautaFisiere("C:\\AdwCleaner", fileName);

        for (int x = 0; x < searchResult.size(); x++) {
            result.append(searchResult.get(x)).append("<br>");
        }
        lblNewLabel.setText("<html>" + result.toString() + "</html>");
    }
});

this is what I was looking for – alin dradici Jan 17 '17 at 16:25 — alin dradici, Jan 17 '17 at 16:25
