Java - ref parameters to achieve a similar C # in Java

Look at the code

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

        Person person1 = new Person();
        PersonWrapper person1Wrapper = new PersonWrapper(person1);

        System.out.println(person1.toString());// Person@4554617c
        System.out.println(person1Wrapper.person.toString());// Person@4554617c
       
        //分别改变包装类和本类的对象引用
        changePerson(person1);
        changePersonWrapper(person1Wrapper);

        System.out.println(person1.toString());// Person@4554617c
        System.out.println(person1Wrapper.person.toString());//Person@74a14482 指针发生了改变

    }

    private static void changePersonWrapper(PersonWrapper personWrapper) {
        personWrapper.person = new Person();
    }

    private static void changePerson(Person person){
        person = new Person();
    }
}


class Person{}

//包装Person类
class PersonWrapper{
    public Person person;

    public PersonWrapper(Person person){
        this.person = person;
    }
}

Here we are by implementing a wrapper class for the Person itself, to implement changes to the internal object fields and references by the process.
This method can be achieved, but I do not know the internal implementation, there is to know, then you can tell me, thank you
