Bigdecimal takes the value of a string

Question

I have the following question, how to accomplish the sum of a BigDecimal with a String.

String a = "8";
BigDecimal b = new BigDecimal(2);

It would look something like this? b.add(a);

Note: I need the logic to be this, I just need to know how to assign the value of a BigDecimal of a variable String.

Answer 1

String a = "8";
BigDecimal a2 = new BigDecimal(a);
BigDecimal b = new BigDecimal(2);
BigDecimal c = b.add(a2);
