Insert java variable in html-styled jTextPane

Question

I'm building a Java Swing interface in which I have a HTML-styled jTextPane, which I use for displaying the current system status. I want to be able to display a few Strings (which may change over time), while using HTML to set the appearance and placement of the text. I use the line of code below to display two strings of them in the jTextPane.

jTextPane1.setText("<html><font size=\"4\" ><b><center> String A here! </center></b></font><br><br><font size=\"3\" ><center> String B here</center></font>");

What I want, is to insert two Strings (A and B) so that I can change them over time. But unfortunately, I cannot find the syntax to insert a String anywhere. Is there a simple way to do this? Thanks in advance.

Define your HTML code as template and use the placeholders %s for stringA and stringB. Then use String.format() to insert your strings. At the end set this in your TextPane.

String template = "<html><font size=\"4\" ><b><center>%s</center></b></font><br><br><font size=\"3\" ><center>%s</center></font>"
String text = String.format(template, stringA, stringB);
jTextPane1.setText(text);

jTextPane1.getDocument().insertString(offset, stringToInsert, attributes);

You can use some constant strings like:

    final String PRE_HTML = "<html><font size=\"4\" ><b><center> ";
    final String MID_HTML = " </center></b></font><br><br><font size=\"3\" ><center> ";
    final String POST_HTML = "</center></font></html>";

And you can set like:

    String strA = "String A";
    String strB = "String B";
    jTextPane1.setText(PRE_HTML + strA + MID_HTML + strB + POST_HTML);

You could use String.format:

jTextPane1.setText(String.format("<html><font size=\"4\" ><b><center> %s </center></b></font><br><br><font size=\"3\" ><center> %s </center></font>", a, b));
