Java how to insert a "power of" symbol?

Question

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?

Answer 1

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

Answer 2

If your output is an html page:

km<sup>2</sup> 

or

km² 

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

Answer 3

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