I'm stuck with javassist. I've added a new method to my object class on runtime.

My object class:

```
package tmp3;

public class Car {
    public Car(){}
}

```

My test class:

```
package tmp3;

import java.lang.reflect.Method;
import javassist.ClassPool;
import javassist.CtClass;
import javassist.CtMethod;
import javassist.CtNewMethod;

public class TestMain {
    public static void main(String[] args) {
        try {

            CtClass ctclass = ClassPool.getDefault().get("tmp3.Car");
            CtMethod newmethod = CtNewMethod.make("public void testPrint() { System.out.println(\"test ok\"); }",ctclass);
            ctclass.addMethod(newmethod);
            ctclass.writeFile();

            for(Method me: ctclass.toClass().getDeclaredMethods()){ //test print, ok
                System.out.println(me.getName());
            }

        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

```

But after that point, I don't know how to call(invoke) it. I've read that javassist has not the capability to invoke methods. Then how can I invoke the method which I've just added with javassist?

I've tried lots of things in two days but had no success. Could you please help me with this?
