}

class Worker {
private String name;
private int age;
private double salary;
private int level;
private Helmet myHelmet;

    public  Worker(String  name,int  age,double  salary,int  level,Helmet  myHelmet){

1.  }
   
    public  void  setName(String  name){
            this.name=name;
    }
    public  String  getName(){
            return  this.name;
    }
   
    public  void  setAge(int  age){
            this.age=age;
    }
    public  int  getAge(){
            return  this.age;
    }
   
    public  void  setSalary(double  salary){
            this.salary=salary;
    }
    public  double  getSalary(){
            return  this.salary;
    }
   
    public  void  setLevel(int  level){
            this.level=level;
    }
    public  int  getLevel(){
            return  this.level;
    }
   
    public  void  setHelmet(Helmet  myHelmet){
            this.myHelmet=myHelmet;
    }
    public  Helmet  getHelmet(){
            return  this.myHelmet;
    }
   
    
    public  void  display(){
            
   

2.  }
   

   }

class Helmet{
private String code;
private String color;
private String checkDate;

    public  Helmet(String  code,  String  color,String  checkDate){
            this.code  =  code;
            this.color  =  color;
            this.checkDate  =  checkDate;
    }
    
    public  void  display(){
            System.out.println("Helmet="  +  code+","+color+","+checkDate);
    }

}

对于这段代码我应该怎么改（只在1、2处修改）
