Use an if statement to test the value of the String to see what it is.
The code will have to have the math operations in it already and use the value of the String to determine which operation to do. There is no way to "compile and execute" a String as a java statement.
If you don't understand my answer, don't ignore it, ask a question.

Re: How to convert from string to math sign
To do addition use the +: x + ykind of math operations
to do subtraction use the -: x - y
etc
if(str.equals("+")) // test the string val = x + y; // do the math operation else id(str.equals("-")) val = x - y;
