how to add @Override annotation to a method while creating the .class file using javaassist?

Question

How to add the @Override annotation to a method while creating the class using javaassist?

ClassPool pool = ClassPool.getDefault();
CtClass ctClasz = pool.makeClass("test.ExampleImpl");
ctClasz.addInterface(pool.get(MyInterface.class.getName()));
CtMethod method = CtNewMethod.make ("@Override public void print() { System.out.println(\"Hello!    \"); }", ctClasz);
ctClasz.addMethod(method);

System.out.println("Implementd: Interfaces:" + ctClasz.getInterfaces());
System.out.println("Methods: " + ctClasz.getMethods());
ctClasz.writeFile("D:");

This code is throwing exception as follows:

 Exception in thread "main" javassist.CannotCompileException: [source error] syntax error

@Override isn't a runtime annotation so even if you could add it, it wouldn't make any difference whatsoever.

For annotations that do have a runtime effect (RetentionPolicy.RUNTIME), you can take a look at this question.
