请问这段程序有啥问题？

Question

public class Person {

String name;

public Person(String personName) {

    name = personName;

}

public String greet(String yourName) {

    return String.format("Hi %s, my name is %s", name, yourName);

}

}

Answer 1

name 和 yourName 位置反了

Answer 2

personName 和 yourname 有些重复吧
