Java 字符串转成运算公式

public static void main(String args[]) {

        Binding binding = new Binding();

        binding.setVariable("F",2.5);
        binding.setVariable("T",30);
        binding.setVariable("A",100);
        binding.setVariable("P0",1)">);

        binding.setVariable("language","Groovy");

        GroovyShell shell =  GroovyShell(binding);

        Object F1 =shell.evaluate("P1=(1+0.1 * (F/100) * T)*P0; return P1 ");

        Object F2 =shell.evaluate("P1=P0*(0.055*0.20+1.0011)+A; return P1 ");

        System.out.println(F1);
        System.out.println(F2);

    }

            Object result = JSFunction.eval(bindings);
            System.out.println(result); 调用缓存着的脚本函数对象，Bindings作为参数容器传入
        } catch (ScriptException e) {
            e.printStackTrace();
        }
