根据需求，完成如下代码（按照标准格式写），并在测试类中进行测试。标准格式包含: 私有属性无参构造有参构造 setter 和getter 需求中的方法需求一：员工类Employee 属性：姓名name,工号id,工资salary 行为：显示所有成员信息的方法show() 需求二：动物类Animal 属性:姓名name,年龄age 行为:吃饭

// 员工类

public class Employee {
   private String name;
   private int id;
   private double salary;

   public void show() {
       System.out.println(name+"\t"+id+"\t"+salary);
   }
   public Employee() {

   }
   public Employee(String name, int id, double salary) {
       this.name = name;
       this.id = id;
       this.salary = salary;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public int getId() {
       return id;
   }
   public void setId(int id) {
       this.id = id;
   }
   public double getSalary() {
       return salary;
   }
   public void setSalary(double salary) {
       this.salary = salary;
   }
}

// 动物类

   public void eat() {
       System.out.println("吃饭");
   }
   public void sleep() {
       System.out.println("睡觉");
   }
}

//人类

public class Person {
   private String name;
   private int age;
   private String gender;

   public Person() {

   }
   public Person(String name, int age, String gender) {

   public void study() {
       System.out.println("学习");
   }

   public void sleep() {
       System.out.println("睡觉");
   }
