class Rectangle extends Shape {
void display() { //实现抽象类的方法
System.out.println("Rectangle");
}
}
class Triangle extends Shape {
void display() { //实现抽象类的方法
System.out.println("Triangle");
}
}
public class AbstractClassDemo{
public static void main(String args]){
(new Circle()).display();//定义无名对象来调用对应的display方法
(new Rectangle()).display();
(new Triangle()).display();
}
}
输出结果是 ?
">6.阅读程序,给出结果:// AbstractClassDemo.java源代码如下:
abstract class Shape { //定义抽象类Shape和抽象方法display
abstract void display();
