Text and variables

Question

Hello Forums,
Just for some fun, i'm trying to make something somewhat
similar to a stat calculator. I'm testing out my design using the
base for a MMORPG game; where as the character level increases they
gain base attributes but also additional attribute points that they
can spend on those attributes. So for example;
A character has, health, attack and defence, at level 1 those
stats are low, at level 2, those stats increase with a predefined
build, however the character also gains 4 additional points which
they can use to raise a specific stat if they wanted to.
So basically saying, at level 100 you would have 400
additional points ontop of your predefined build, I have an 'Input
Text Box' where you obviously type in your level, then I am using a
'Dynamic Text Box' which is to display how many additional points
you will have at what level.
My question is, how can I set up a variable (through the
'Input Text Box') where whatever number you were to type in, it
would be multiplied by another number and then displayed (from the
'Dynamic Text Box')
Thanks in advanced to anyone who can understand and
answer.

You can use the default (StringBuilder) like this
String result = "My Text" + otherText;
Or you can use String.format
String result = String.format ("My text is this %1$s, the other value is this %2$s", otherText, text3);
