阅读以下说明和Java代码，将应填入(n)处的字句写在对应栏内。

[说明]

本程序的功能是给公司的员工Tom，Jack，Green增加薪水。三人的职位分别是programmer， Manager，CEO。

程序由6个类组成：WorkerTest是主类，programmer，Manager，CEO三个类，薪水增加的规则是 programmer的涨幅是5%；Manager的是10%；CEO也是Manager，但是它除了有Manager的涨幅，还有1000元的bonus。接口SalaryRaise提供了一个增加薪水的方法raise()。

[java程序]

public class WorkerTest {

public WorkerTest() {}

public static void main(String[] args) {

Programmer programmer = new Programmer("Tom" ,3000);

Manager manager = new Manager("Jack" ,4000);

CEO ceo = new CEO("Green" ,4000);

Worker [] worker = new Worker[3];

programmer, raise();

manager, raise();

ceo. raise();

worker[0] = programmer;

worker [1] = manager;

worker[2] = ceo;

for (int i = 0 ;i ＜ worker, length; i + + ) {

System. out. prinfln (" Name:" + worker [i]. getName () +" \ tSalary:" + worker [i]. getSalary ());

public interface SalaryRaise { void raise(); }

public class Worker {

public String name;

public double (1);

public Worker() {}

public String getName() {return name;}

public void setName(String name) {this. name = name;}

public double getSalary() {return salary;}

public void setSalary(double salary) { this. salary = salary; }

}

public class Programmer extends Worker implements (2) {

public Programmer() {}

public void raise() {

double pets=0.05;

double sala = this. getSalary() * (1 + pers);

this. setSalary (sala);

public Programmer(Siring name, double salary) t

this. name = name;

this. salary = salary;

public class Manager extends (3) implements SalaryRaise {

public Manager() { }

public Manager(String name, double salary) {

this. name = name;

this. salary = salary;

}

public void raise() {

double pets = 0.1;

double sala = this. getSalary() * (1 + pers);

this. setSalary(sala);

}

}

public class CEO extends Manager implements SalaryRaise {

public CEO() {}

public CEO(String name,double salary) {

this. name = name;

this. salary = salary;

}

public void raise() {

double bonus = 1000;

(4);

double sala = this. getSalary();

(5);

this. setSalary(sala);

}
