设有语句Employee A = new Employee( );，则语句中的第二个Employee代表（ ）。
A: 类
B: 构造方法
C: 对象
D: 重载
A: 类
B: 构造方法
C: 对象
D: 重载
举一反三
- 中国大学MOOC: 设有语句Employee A = new Employee( );，则语句中的第二个Employee代表（ ）。
- 已知：class Employee;class Manager extends Employee;class Director extends Employee;则以下语句能通过编译的有哪些？ A: Employee e = new Manager(); B: Director d = new Manager(); C: Director d = new Employee(); D: Manager m = new Director()
- 有如下类的定义，创建Employee对象正确的是（） public class Employee{ private int age; private String name; public void Employee(){ } public Employee(int age){ this.age = age; } public Employee(String name){ this.name = name; } } A: Employee e = new Employee( ) B: Employee e = new Employee(10); C: Employee e = new Employee(tom); D: Employee e = new Employee(10,"tom");
- 有如下类的定义，创建Employee对象错误的是（） public class Employee{ private int age; private String name; public Employee(int age){ this.age = age; } public Employee(String name){ this.name = name; } public Employee(int age,String name){ this(age); this.name = name; } } A: Employee emp = new Employee(10); B: Employee emp = new Employee("Tom"); C: Employee emp = new Employee(); D: Employee emp = new Employee(10,"Tom");
- 已知类关系如下:ClassEmployee{}ClassManagerextendsEmployee{}ClassDirectorextendsEmployee{}则下列语句正确的是:()。 A: Employee e=new Manager(); B: Director d=new Manager(); C: Director d =new Employee (); D: Manager m=new Director ();
