定义民政业务类 Person

民政业务类 Person 可以定义如下：

public class Person {
    private String name;
    private int age;
    private String idNumber;
    private String address;

    public Person(String name, int age, String idNumber, String address) {
        this.name = name;
        this.age = age;
        this.idNumber = idNumber;
        this.address = address;
    }

    // getter and setter methods
}

该类包含了姓名、年龄、身份证号码和地址等属性，并提供了相应的构造方法和 getter/setter 方法。
