Question

求JAVA高手，使用抽象类及抽象方法abstract编成！

抽象类及抽象方法abstract
设置抽象类：Employee，成员变量：工号，姓名
方法包括：构造函数Employee(string, string)
设置姓名setName()
获得工号getNumber()
获得姓名getName()
抽象方法：获取状态getStatus()
设置子类：FullTimeEmployee和PartTimeEmployee，继承Employee超类，并实现抽象方法getStatus，分别输出"Full-Time"及“Part-Time”

Answer 1

代码很简单，完全可以自己写的，以下代码供参考：
public abstract class Employee {
private String empNo;
private String name;
public Employee(String empNo, String name) {
super();
this.empNo = empNo;
this.name = name;
}
public String getEmpNo() {
return empNo;
}
public void setEmpNo(String empNo) {
this.empNo = empNo;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public abstract String getStatus();

}

public class FullTimeEmployee extends Employee {
public FullTimeEmployee(String empNo, String name) {
super(empNo, name);
}
@Override
public String getStatus() {
return "Full-Time";
}
}
public class PartTimeEmployee extends Employee {
public PartTimeEmployee(String empNo, String name) {
super(empNo, name);
}
@Override
public String getStatus() {
return "Part-Time";
}
}
public class Test {
public static void main(String[] args) {
new Test().exec();
}
private void exec(){
Employee emp1 = new FullTimeEmployee("001", "张三");
Employee emp2 = new PartTimeEmployee("002", "李四");

System.out.println(emp1.getStatus());
System.out.println(emp2.getStatus());
}
}
