Java decimal point given by user

How to printf decimal point by user? For example:

float a = 122.32445;

int decimal = 2;

And I want to print 122.32 I know that exist:

System.out.printf("%.2f", a);

But how to implement that decimal point there? I came up with something like this:

System.out.printf("%.%df, decimal, a);

But it of course it doesn't work. Thanks for any help.

I would assume that 

DecimalFormat decimalFormat = new DecimalFormat("##,##0.00");

does the trick.
