Can you post some code examples of what you are trying to do?
The String class has methods for getting at sub parts of the string.
I don't know what you mean by "sub scripting integer variables".
You can get at bits in an int variable by using the AND (&) operator and shifting.

alright, well say you have beryllium and Nitrogen, the beryllium has a charge of +2, and nitrogen -4, so when combined, they would be Be(subscripted 4)N(subscripted 2)

What you posted looks like notation for chemistry. I don't understand chemistry, so you'll need to show what you want to do in a java program.

That is exactly what I want to do. I need the 2 and the 4 subscripted, but not as strings so they can be changed. It has nothing to do with chemistry, code wise, it just means I want to have the numbers subscripted.

Do you just want them subscripted when printing? You could do that by displaying strings as HTML.

Are you talking about the contents of a String? You want to use characters in a String that will display as subscripts.
Try asking Google for the Unicode values for the characters you want.

ah ok, but do you seriously think I haven't tried that? should there not be an easy way to do this? I've wasted at least 3 days on this already.

Not many people print characters that are not in the basic ASCII character set.
What did you find for Unicode character values for the characters you want to print/display? What have you tried?

No, I don't. It took me about 2 minutes:
java Code:
 Original
- java Code |

public static void main ( String[] argv ) { String subScript = "Be\u2084N\u2082"; System. out. println( "the string is \"" + subScript + "\"" ); } }
As my Google search revealed, superscript characters are in the x2070 to x2079 range and subscript are in the x2080 to x2089 range. However, the giant caveat is that whatever font set you are using must have those characters in it, otherwise it will display some junk character. On my Ubuntu command line, for example, not all of the superscript characters are represented.
