How can I convert strings to operators in Java?

Question

I have "+" and I want to use it as "if(1 + 2 == 3)"

Do you mean that you want to know how to write a program that parses a mathematical expression (like "1 + 2 == 3")? — siride, Jul 16 '11 at 03:13
Java does not have eval, if that's what you mean. For that, use JavaScript / ECMAScript. — wberry, Jul 16 '11 at 03:15

If you want to evaluate "1+2" as a mathematical equation: Evaluating a math expression given in string form

If you want to evaluate if(1+2==3) as an if statement, java should do that for you.
