java8.抽象类的应用

1.代码示例：

abstract class Person {
// age和name是所有人共有的属性
private int age;
private String name;

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

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public String getName() {
return name;
}

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

// 每个群体所想要的都不一样，可以声明为抽象方法
public abstract void want();
}

class Student extends Person {
// 由于父类含有构造方法，所以子类也需要自己的构造方法
public Student(int age, String name, int score) {
super(age, name);
this.score = score;
}

private int score;

public int getScore() {
return score;
}

public void setScore(int score) {
this.score = score;
}

public void want() {
System.out.println("姓名：" + getName() + "年龄：" + getAge() + "成绩："
+ getScore());
}
}

class Worker extends Person {
private int money;

public int getMoney() {
return money;
}

public void setMoney(int money) {
this.money = money;
}

public Worker(int age, String name, int money) {
super(age, name);
this.money = money;
}

public void want() {
System.out.println("姓名：" + getName() + "年龄：" + getAge() + "工资："
+ getMoney());
}

}

public class AbsDemo01 {

public static void main(String[] args) {
Student s = new Student(10, "小明", 98);
s.want();
Worker w = new Worker(35, "大明", 5000);
w.want();
}
}
