java第十一周周总结

这周我们学习了类的多态，和类的重载方法和继承

public class Student4 { 
        private String name; 
    
	      public String getName() { 
           return name; 
 }    
       public void setName(String name) { 
           this.name = name; 
      } 
   
     /** 
      * 喂养方法 
     * 
     * @param animal 
     */ 
public void feed(Animal animal) { 
      animal.move(); 
      animal.eat(); 
      } 
} 

3、创建TestStudent4类
 public class TestStudent4 { 
     public static void main(String[] args) { 
     Student4 student4 = new Student4();    
     Dog dog = new Dog(); 
	 dog.setName("瑞瑞"); 
     dog.setAge(3); 
  
      student4.feed(dog); 
    
       Cat cat = new Cat(); 
       cat.setName("欢欢"); 
       cat.setAge(5); 
    
	   student4.feed(cat); 
 
        Bird bird = new Bird(); 
        bird.setName("灵灵"); 
        bird.setAge(2); 
       student4.feed(bird); 
  }   } 

这个代码是老师讲课笔记里照着打的，我觉得很完美的诠释了类的多态

下周的学习我将更加努力，为学好java而奋斗。
