请阅读程序,写出程序运行结果。 class A{ static String name ="tom"; static int getX() { return 2; } int getY() { return 3; } } class B extends A{ static String name ="Tuny"; static int getX() { return 4; } int getY() { return 5; } } class C extends A{ static String name ="Tuny"; static int getX() { return 4; } int getY() { return 5; } } interface D{ int getY(); } class E implements D{ public int getY() { return 6; } } public class Demo{ public static void main(String[] args) { A a= new A(); A b= new B(); A c= new C(); D d= new E(); int sum=a. name .length()+b. getX ()+c.getY()+d.getY(); System. out .println(sum); } }
