JAVA编程——父子类

编程需求

需求如下： 编写父类People，子类Student继承自People类。父类People具有姓名，性别，年龄等性质，还具有吃和说的行为。子类Student继承父类People，还拥有学号性质和学习行为。构造People类和Student类的对象，调用吃、说、学习的方法输出有关信息。

代码描述：

第一个类

class People {
    protected static String name;
    protected static String sex;
    protected static int age;

    public void eat(){
        System.out.println("吃吃");
    }
    public void speak(){
        System.out.println("喝喝");
    }

    public People (String name,String sex,int age) {
        this.name = name;
        this.sex = sex;
        this.age = age;
    }
}

class Student extends People {
    protected long stuNo;

    public void eat() {
        System.out.println("饭饭");
    }

    public void speak() {
        System.out.println("话话");
    }

    public void learn() {
        System.out.println("学学");
    }
    public Student(String name,String sex,int age,long
                   stuNoNo){
        super(name,sex,age);
        this.stuNo =stuNoNo;
    }
}

第二个类

public class Test {
    public static void main(String[] args) {
        Student student = new Student("大丘丘","boy", 1, 0000);
        People people = new People("二丘丘","boy", 2);
        System.out.println("学生：");
        System.out.println("姓名"+student.name);
        System.out.println("性别"+student.sex);
        System.out.println("年纪"+student.age);
        System.out.println("学号"+student.stuNo);
        student.eat();
        student.speak();
        student.learn();
        System.out.println("普通人：");
        System.out.println("姓名："+People.name);
        System.out.println(""+people.name);
        System.out.println("年龄："+people.sex);
        people.eat();
        people.speak();
    }
}

总结

希望对大家有帮助！！！
