以下程序定义了父类Employee和子类Manager。程序将输出：Jim 2。
class Employee{
private String name;
static int ID=0;
public Employee(String s){
name= s;
ID++;
}
String getName(){ returm name; }
int getID(){ retum ID; }
}
class Manager extends Employee{
private String department;
public Manger(String s, Sting d){
_______①___________;
department= d;
}
String getDepart(){ returm department; }
}
public class Test27{
public static void main(Sring[] args) {
Employee jim = new Employe("Jim");
Manager adom = new Manager("Adom", "HR");
System.out. println(jim._____②__________+*"+jm._____③_________);
}
}
