java编写类

public class Employee{
String name;
int number;
public Employee(String name,int number){
this.name=name;
this.number=number;

}
public void listInfo(){
}
public double raiseSalary(double proportion){
return 自己写......

}

}

public class Manager extends Employee{
private String officeID;
private double bonus;
public Manager(String name,int number,String officeID,double bonus){
super(name,number);
this.officeID=officeID;
this.bonus=bonus;

}
public void listInfo(){
}
public double raiseSalary(double proportion){
return 自己写......
}
}
基本是这样了，具体方法里面怎么实现看题目的需求啦，纯属手写，望采纳！！
