Java execute math equation

Question

As you'll probably be able to tell by my way of doing things, I'm a beginner when it comes to Java. Basically I have something like this:

 String math = "1 + 1";

I want to be able to execute that math equation so that it will return the value 2. Something presumably like this:

 String math = "1 + 1";
 int answer = Math(math);
 System.out.print(answer);

How would I go about doing this? Thanks in advance.

How about trying something and coming back when you have a specific question? You probably need to start by splitting the string into numbers and operators. — John3136, Feb 19 '14 at 22:21
