在C#中假设Class1是一个类，而IExample是一个接口，下面的（ ）类声明是正确的。
A: class Employee: Class1, IExample
B: class Employee: IExample, Class1
C: class Employee- Class1, IExample
D: class Employee: Class1/Iexample
A: class Employee: Class1, IExample
B: class Employee: IExample, Class1
C: class Employee- Class1, IExample
D: class Employee: Class1/Iexample
举一反三
- 以下语句能顺利通过编译： abstract class class1 { } public class mainClass { public static void main（String args[]) { class1 cs1=new class1（); } } 。（)
- class Employee; class Manager extends Employee; class Director extends Employee;
- 以下程序的运行结果是______ abstract class class1{abstract void method1();}class class2 extends class1{public void method1(){ System.out.println("子类");}｝public class MainClass{public static void main(String args[]){class1 ac=new class2();ac.method1();}}
- 已知类的继承关系 class Employee; class Manager extends Employee; class Director extands Employee; class Director extands Employee; 下语句能通过编译的有哪些?
- class Class1 { public static int Count = 0; static Class1() { Count++; } public Class1() { Count++; } } Class1 o1 = new Class1(); Class1 o2 = new Class1(); 请问，Class1.Count的值是多少？( )( 2 分)
