Java中的多级继承
多级继承-类从再次继承属性的类继承属性。
示例
class Shape {
public void display() {
System.out.println("Inside display");
}}
class Rectangle extends Shape {
public void area() {
System.out.println("Inside area");
}
}
class Cube extends Rectangle {
public void volume() {
System.out.println("Inside volume");
}
}
public class Tester {
public static void main(String[] arguments) {
Cube cube = new Cube();
cube.display();
cube.area();
cube.volume();
}
}输出结果
Inside display Inside area Inside volume
