Java简单类，（康复训练1）

定义并测试一个代表员工的Employee类。员工属性包括"编号",“姓名”, “基本薪资”,“薪水增长率”,还包括计算薪水增长额及计算增长后的工资总额的操作方法。

设计一个Dog类，有名字，颜色，年龄等属性，定义构造方法来初始化类的这些属性，定义方法输出Dog信息。

class  Dog{
    private  String name;
    private  String color;
    private  String age;

    public Dog() {
    }

    public Dog(String name, String color, String age) {
        this.name = name;
        this.color = color;
        this.age = age;
    }

    @Override
    public String toString() {
        return "Dog{" +
                "name='" + name + '\'' +

                ", age='" + age + '\'' +
                '}';
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }
}
public class JavaDemo4 {
    public static void main(String[] args) {
        Dog dog = new Dog("小帅","雄性","1");
        System.out.println(dog.toString());
