Java继承代码案例，不多说，直接敲代码

### Animal 类 ###

/** * @Author 公众号「MarkJava」 * @Date 2020/11/9 15:08 **/
    public class Animal { 
        private String name;
        private int month;
        private String species;
        public Animal() { }
        public Animal(String name, int month, String species) { 
            this.name = name;
            this.month = month;
            this.species = species;
        }
        public String getName() { 
            return name;
        }
        public void setName(String name) { 
            this.name = name;
        }
        public int getMonth() { 
            return month;
        }
        public void setMonth(int month) { 
            this.month = month;
        }
        public String getSpecies() { 
            return species;
        }
        public void setSpecies(String species) { 
            this.species = species;
        }
        @Override
        public String toString() { 
            return "Animal{" +
                    "name='" + name + '\'' +
                    ", month=" + month +
                    ", species='" + species + '\'' +
                    '}';
        }
    }

### Cat 类 ###

/** * @Author MarkJava * @Date 2020/11/9 15:10 **/
    public class Cat extends Animal{ 
        private double weight;
        public Cat(){ }
    
        public double getWeight() { 
            return weight;
        }
    
        public void setWeight(double weight) { 
            this.weight = weight;
        }
        //跑步方法
        public String run(){ 
            return getName() + ",是一只属于" + getSpecies() + "的动物，它在奔跑中！";
        }
    
    }

### Dog 类 ###

/** * @Author 公众号「MarkJava」 * @Date 2020/11/9 15:20 **/
    public class Dog extends Animal{ 
        private int age;
        public Dog(){ }
        public int getAge() { 
            return age;
        }
        public void setAge(int age) { 
            this.age = age;
        }
        //狗会叫的方法
        public String call(){ 
            return getName()+ ",今年" + getAge() + "岁，它是属于" + getSpecies()+ "动物的,会旺旺地叫...";
        }
    }

### 测试类 ###

/** * @Author 公众号「MarkJava」 * @Date 2020/11/9 15:15 **/
    public class Test { 
        public static void main(String[] args) { 
            //cat
            Cat cat = new Cat();
            cat.setName("白猫");
            cat.setSpecies("猫类");
            System.out.println(cat.run());
            //Dog
            Dog dog = new Dog();
            dog.setName("旺财");
            dog.setAge(2);
            dog.setSpecies("狗类");
            System.out.println(dog.call());
        }
    }
