Java之抽象类

public abstract class Persons {
	private String name;
	private int age;
	
	public Persons(String name, int age) {
		this.name = name;
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public int getAge() {
		return age;
	}
	public abstract void show();
}
public class Students extends Persons{
	public Students(String name, int age, String num, double score) {
		super(name, age);
		this.num = num;
		this.score = score;
	}

	private String num;
	private double score;
	
	@Override
	public void show() {
		// TODO Auto-generated method stub
		System.out.println("姓名="+this.getName()+",年龄="
		+this.getAge()+",学号="+num+",成绩="+score);
	}
}
public class Test {
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Students stu=new Students("张三", 18, "1002", 99);
		stu.show();
	}

}
