set方法和get方法

手写set方法和get方法

public class Person01 {
    
    private String nickname;

    
    private int gender;

    
    private int age = 18;

    public void setNickname(String name) {
        nickname = name;
    }

    public String getNickname() {
        return nickname;
    }

    public void setGender(int sex) {
        gender = sex;
    }

    public int getGender() {
        return gender;
    }

    public void setAge(int nianling) {
        age = nianling;
    }

    public int getAge() {
        return age;
    }


}

使用IDEA快捷键创建set方法和get方法

alt+ins如下

public class Person02 {
    
    private String nickname;

    
    private int gender;

    
    private int age = 18;

    public void setNickname(String nickname) {
        nickname = nickname;
    }

    public String getNickname() {
        return nickname;
    }

    public void setGender(int gender) {
        gender = gender;
    }

    public int getGender() {
        return gender;
    }

    public void setAge(int age) {
        age = age;
    }

    public int getAge() {
        return age;
    }

}

lombok注解自动生成set方法和get方法

@Setter
@Getter
public class Person06 {
    
    private String nickname;

    
    private int gender;

    
    private int age = 18;
}
     * 性别 1代表男性 0代表女性
     */
    private int gender;

    
    private int age = 18;
}
