public class Employee {
private int id;
private String name;
private double salary;
public Employee() {
this.id = 0;
this.name = null;
this.salary = 0.0;
}
public Employee(int id, String name, double salary) {
super();
this.id = id;
this.name = name;
this.salary = salary;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
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;
}
}
代码一：
private Double weeklySalary;
代码二：
public void setWeeklySalary(Double weeklySalary){
this.weeklySalary=weeklySalary;
}
代码三：
private Double salary;
private Integer piece;
public PieceWorker (String name,Integer p,Double s) {
super(name);
setSalary(s);
setPiece(p);
}
public void setPiece(Integer p){
this.piece=p;
}
public void setSalary(Double s){
this.salary=s;
}
public double earnings() {
return piece*salary;
}
代码四：
private Double salary;
private Integer hour;
public PieceWorker (String name,Integer h,Double s) {
super(name);
setSalary(s);
setHour(h);
}
public void setHour(Integer h){
this.hour=h;
}
public void setSalary(Double s){
this.salary=s;
}
public double earnings() {
return h*salary;
}
