A Java function to Generate Mock data CODE by taking a Java Object

Is there a Java function to Generate Mock data CODE by taking a Java Object? The output uses the existing setter but not constructor. Say such a function named void Generate(Class<T> klazz)

Generate(person);//person is a POJO with data in it.

This will sysout the following in stdout.

Person mockPerson = new Person;
mockPerson.setName("name");
mockPerson.setAge(1);

I believe this may take advantage of Java Reflection.
