6-1 Java类实现-小狗类输出样例： Puppy's age is : 2 Puppy's name is : wangzai Puppy's sex is : male

好的，这是一个小狗类的示例代码，可以实现输出小狗的年龄、名字和性别：

public class Puppy {
    private int age;
    private String name;
    private String sex;
    
    public Puppy(int age, String name, String sex) {
        this.age = age;
        this.name = name;
        this.sex = sex;
    }
    
    public int getAge() {
        return age;
    }
    
    public String getName() {
        return name;
    }
    
    public String getSex() {
        return sex;
    }
    
    public void setAge(int age) {
        this.age = age;
    }
    
    public void setName(String name) {
        this.name = name;
    }
    
    public void setSex(String sex) {
        this.sex = sex;
    }
    
    public void printInfo() {
        System.out.println("Puppy's age is : " + age);
        System.out.println("Puppy's name is : " + name);
        System.out.println("Puppy's sex is : " + sex);
    }
}

你可以根据需要调用该类的构造方法和方法，实现对小狗对象的创建和信息输出。例如：

Puppy puppy = new Puppy(2, "wangzai", "male");
puppy.printInfo();

以上代码会输出：

Puppy's age is : 2
Puppy's name is : wangzai
Puppy's sex is : male
