public class Dog {

        //尝试编写一个类，定义一个修饰权限为private的成员变量，
        //定义两个成员方法，一个方法实现为此成员变量赋值，
        //另一个成员方法获取这个成员变量的值，保证其他类继承该类时能获取该类的成员变量的值。

    //品种
    private String type;
    //年龄
    private int age;
    //颜色
    private String color;
    //重量
    private double weight;

        return type;
    }

        this.type = type;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getColor() {
        return color;
    }

        this.color = color;
    }

        return weight;
    }
    public void setWeight(double weight) {
        this.weight = weight;
    }
    public Dog(String type, int age, String color, double weight) {
        super();
        this.type = type;
        this.age = age;
        this.color = color;
        this.weight = weight;
    }
    public void texing(double weight)
    {
        if(weight<70)
        {
            System.out.println("您的狗狗偏瘦，处于亚健康状态");
        }
        else if(weight>100)
        {
            System.out.println("您的狗狗过于肥胖，请及时锻炼");
        }
        else
        {
            System.out.println("体重正常，符合达标");
        }
    }
    
    public static void main(String[] args)
    {
        Dog myAlasijia=new Dog("阿拉斯加");
        System.out.println("品种="+myAlasijia.getType());
        System.out.println("年龄="+myAlasijia.getAge());
        myAlasijia.texing(80);
        System.out.println("当前状况为："+myAlasijia.getWeight());
    }

初始化Dog时出现错误，希望老师指点。
