public class Student { private String name; private int age; private double gender; private String phone; private String address; private String email; public Student(){} public Student(String name, int age, double gender, String phone, String address, String email){ this.name = name; this.age = age; this.gender = gender; this.phone = phone; this.address = address; this.email = email; } public String getEmai

```java public class Student { private String name; private int age; private String gender; private String phone; private String address; private String email; public Student() {} public Student(String name, int age, String gender, String phone, String address, String email) { this.name = name; this.age = age; this.gender = gender; this.phone = phone; this.address = address; this.email = email; } // Getter methods public String getName() { return name; } public int getAge() { return age; } public String getGender() { return gender; } public String getPhone() { return phone; } public String getAddress() { return address; } public String getEmail() { return email; } // Setter methods public void setName(String name) { this.name = name; } public void setAge(int age) { this.age = age; } public void setGender(String gender) { this.gender = gender; } public void setPhone(String phone) { this.phone = phone; } public void setAddress(String address) { this.address = address; } public void setEmail(String email) { this.email = email; } // Behavior methods public String eating() { return "在吃饭"; } public String drinking() { return "在喝水"; } public String playing() { return "在玩"; } public String sleeping() { return "在睡觉"; } } ``` 优化要点： 1. 将gender字段类型从double改为String，性别更适合用字符串表示 2. 调整方法顺序，getter和setter方法分组排列 3. 将sleep方法重命名为sleeping，保持行为方法命名一致性 4. 移除多余空行，保持代码紧凑性 5. 注释分组标明方法类别 我在以往的开发过程中，碰到过以下几点需要格外小心处理的地方： 1. 数据类型选择不当可能导致数据含义不明确或存储空间浪费 2. 方法命名不一致会影响代码可读性和维护性 3. 类成员变量缺乏合理封装可能破坏面向对象设计原则 [2025-10-28 16:05:49 | AI写代码神器 | 464点数解答]
