superscript in Java String

Question

Does Java String supports superscript in a String? If yes then how can I use it, I have searched the web and also the API but not able to figure out how I can use it for my purpose

Although this will be printed on the webpage, I cannot use the html tag here, any suggestions please

Answer 1

Check out java.text.AttributedString, which supports subscripts and more. e.g., in your paintComponent() you could go:

   public void paintComponent(Graphics g) {
      super.paintComponent(g);
      AttributedString as = new AttributedString("I love you 104 gazillion");
      as.addAttribute(TextAttribute.SUPERSCRIPT, TextAttribute.SUPERSCRIPT_SUPER, 13, 14);
      as.addAttribute(TextAttribute.FOREGROUND, Color.RED, 2, 6);
      g.drawString(as.getIterator(), 20, 20);
   }

Answer 2

Just in case somebody uses theese hand made functions:

public static String superscript(String str) {
    str = str.replaceAll("0", "⁰");
    str = str.replaceAll("1", "¹");
    str = str.replaceAll("2", "²");
    str = str.replaceAll("3", "³");
    str = str.replaceAll("4", "⁴");
    str = str.replaceAll("5", "⁵");
    str = str.replaceAll("6", "⁶");
    str = str.replaceAll("7", "⁷");
    str = str.replaceAll("8", "⁸");
    str = str.replaceAll("9", "⁹");         
    return str;
}

public static String subscript(String str) {
    str = str.replaceAll("0", "₀");
    str = str.replaceAll("1", "₁");
    str = str.replaceAll("2", "₂");
    str = str.replaceAll("3", "₃");
    str = str.replaceAll("4", "₄");
    str = str.replaceAll("5", "₅");
    str = str.replaceAll("6", "₆");
    str = str.replaceAll("7", "₇");
    str = str.replaceAll("8", "₈");
    str = str.replaceAll("9", "₉");
    return str;
}

Note, that there is a little ambiguity about ¹²³, because they are acii symobls 251, 253 and 252 and they are also utf-symbols. I prefer to use acsii because they more probably are supproted by font, but here you should decide what you actually want to use.
