how to change method annotation using reflection in java

I want to change method annotation using reflection in java

here is a snapshot:

can you suggest?.

final List<Method> allMethods = new ArrayList<Method>(Arrays.asList(klass.getDeclaredMethods()));
    Method thisMethod = allMethods.stream().filter(m->m.getName()   == "getWithPathParam" ).findFirst().get();

    Annotation[][] parameterAnnotations = thisMethod.getParameterAnnotations();
    for(Annotation[] annotations : parameterAnnotations){
        for(Annotation annotation : annotations){
            if(annotation instanceof ApiParam){
                Annotation newAnnotation = new ApiParam() {
                    @Override
                    public String allowableValues() {
                        return "test";
                    }

                    @Override
                    public Class<? extends Annotation> annotationType() {
                        return annotation.annotationType();
                    }
                };

here I want basically to exchange annotation field with newAnnotation field

it is possible?
