关于#java#的问题，请各位专家解答！

package emppackage;

class Mydate{
    private int year;
    private int month;
    private int day;
    public  Mydate(int year,int month,int date) {
        this.year=year;
        this.month=month;
        this.day=date;
    }
    public String toDateString()
    {
        return year+"年"+month+"月"+day+"日";
    }
}

abstract class employee1{
private String name;    
private String num;
private Mydate birthday;
abstract public int earnings();
public employee1(String name,String num,Mydate birthday)
{this.name=name;
 this.num=num;
 this.birthday=birthday;
    
}
public String toString()
{
    return "姓名:"+name+","+"工号:"+num+","+"生日:"+birthday.toDateString();
}

}


class SalariedEmployee extends employee1{
    private int monthlysalary;
    public SalariedEmployee(String name,String num,Mydate birthday,int monthlysalary){
        super(name,num,birthday);
        this.monthlysalary=monthlysalary;
    }
    public int earnings() {
        return monthlysalary;
    }

    public String toString(){                    
        return "月工:"+super.toString();      
    }    



 class HourlyEmployee extends employee1{
    private int hour;
    private int wage;
    public HourlyEmployee(String name,String num, Mydate birthday,int hour,int wage){
        super(name,num,birthday);
        this.hour=hour;
        this.wage=wage;
    }
    public int earnings(){
        return hour*wage;
    }

    public String toString(){
        return "小时工"+super.toString();
    
    }
    
}
 
 
public class Employee {
    public static void main(String args[]){
    employee1 c1[]=new employee1 [4];
    Mydate a=new Mydate(2000,11,120);
    c1[0]=new SalariedEmployee("张三","202226",a,3000);
    System.out.println("c1.toString()");    
}
}

怎么修改gets（）输出信息

刚才怎么删了？ 我给你改了，参考如下：
gets() 没必要调用，如果你想用，也可以 super.gets()
