Hello I have a program that displays the area of some land. The number is 1900 square kilometers. I want to write this as 1900 km2 but the two should look like a "to the power of 2" symbol. Is there a way I can insert a symbol like that?

    How? Print to console, or some form of UI, or output in a doc, or what? Java supports unicode. Have you tried just `System.out.println("1900 km²");`? – tobias_k Aug 27 '15 at 14:59
  • Do you mean `^` or you want superscript? – Ivaylo Strandjev Aug 27 '15 at 15:00

  • My keyboard has a Shortcut for it: AltGr+2 makes a ². Other than that, Java files upport Unicode. Just get the character somewhere from the Internet and copy/paste into your source file. – Thomas Weller Aug 27 '15 at 15:02

  • The console only has one font, unlike HTML. This means if you want super script you have to use different characters. http://www.fileformat.info/info/unicode/char/b2/index.htm – Peter Lawrey Aug 27 '15 at 15:17

Unicode code u00B2 will give you the superscript two symbol. Try the following:

 System.out.println("km\u00B2");

Working example

You could alternatively use the extended ASCII code alt + 253 as stated here

If your output is an html page:

km<sup>2</sup>

or

km&sup2;

If your output is a String to the console 

System.out.println("km\u00B2");

Other outputs

If you need to print it to other systems (pdf, excel...) and they accept unicode values use the char '\u00B2' for the 2 at the exponent

You can try to use the "SUPERSCRIPT TWO" Unicode Character (escape code \u00B2) if your font supports it.

You can use the string literal "km\u00B2", or just use km² directly in your source code if you are using a unicode-supporting file encoding.
