写一个实体类成员类例子

下面是一个示例实体类成员类:
```java
public class Person {
private String name;
private int age;
private Address address;
public Person(String name, int age, Address address) {
this.name = name;
this.age = age;
this.address = address;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
public static class Address {
private String street;
private String city;
private String state;
public Address(String street, String city, String state) {
this.street = street;
this.city = city;
this.state = state;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
}
}
```
这个例子中,`Person`类包含一个`Address`成员类。该类被定义为`static`,因此可以在没有创建`Person`对象的情况下直接访问它。`Address`类包含三个属性(`street`、`city`和`state`),它们都有对应的getter和setter方法。`Person`类也有类似的getter和setter方法,但它们用于访问`Person`对象的属性。在创建`Person`对象时,需要提供一个`Address`对象,以便初始化`address`属性。
