Question

I want to use the infinity symbol (8 lying sideways) in java.

furthermore i want to use it as a String component.
i did not find a working charcode/ascii code for this (is there any?).

i tried:

String s=Character.toString(236);
String s=Character.toString('236');

am i missing something?

i got this now:

System.out.println(Character.toString('\u221E'));

but the output is ?

i am using java 1.7 jdk and eclipse. why is the infinity sign not showing up?

Answer 1

You need the Unicode infinity sign, U+221E. 236 is a Windows typing convention, that won’t help you at all. '\u221e' is the character constant.

Now, I can’t promise that this will result in any ∞ characters on your screen. That depends on what sort of computer you have, what font you are using, and what you set in -Dfile.encoding. Also see this question.
