<init>在Java异常中表示什么？

public class Person {
    private String name;

    public Person(String name) {
        this.name = name;
    }
}

public class Person {
    private String name;

    public Person(String name) {
        this.name = name;
        throw new IllegalArgumentException("Invalid name");
    }
}

public void main() {
    try {
        Person person = new Person("John");
    } catch (IllegalArgumentException e) {
        System.out.println("Invalid name");
    }
}
