在main中调用出错，是不是写少了什么

//package fourth;
 //要求：创建一个corporation类，以基本工资和工作小时为参数，计算出总工资或错误信息，在main()方法中每一个员工调用这个方法
 public class corporation {
     String name;
     double basicWage;
     int workHours;
     public corporation(String name,double basicWage,int workHours)
     {    this.name=name;
         this.basicWage=basicWage;
         this.workHours=workHours;
         
         float wage;
         //基本工资小于8元。报错
         if(this.basicWage<8)
             System.out.println("Error!");
         else
         {    //工作时间<40,，基本工资=工作小时*基本工资
             if(this.workHours<=40)
             {    wage=(float)(this.workHours*this.basicWage);
                 System.out.println(this.name+"  "+wage);
             }
                 //40<工作时间<=60,，超时工资=基本工资*1.5
             else if(40<this.workHours && this.workHours<=60)
             {    wage=(float)(40*this.basicWage+(this.workHours-40)*this.basicWage*1.5);
                 System.out.println(this.name+"  "+wage);
             }
             //工作时间超过60小时，则出错
             else
                System.out.println("Error!");
         }
     }   

public static void main(String[] args) {
     corporation cor1=new corporation("员工1",7.50,35);
     corporation cor2=new corporation("员工3",8.20,47);
     corporation cor3=new corporation("员工3",10.00,73);
     
    }
 }

谢谢！
