While预期错误

Question

我不断地得到这个错误，我并没有试图解决它。

包bonuscalc；

导入java.text.DecimalFormat；导入java.util.scanner；

公共类BonusCalc{/***@param args命令行参数*/public static void main(String[]args){

     Scanner input = new Scanner(System.in); 
     DecimalFormat formatter = new DecimalFormat("#0.00");

     int Salary;
     double NewSal, Comm;
     double p1 = 0.1;
     double p2 = 0.15;
     double p3 = 0.2;
     double p4 = 0.3;

     System.out.println("Welcome to Bonus Calculator");

     do{
        System.out.print("Enter your Salary: ");
        Salary = input.nextInt();
       }While (Salary < 0)

     if((Salary >  0) && (Salary <= 8000)){
         Comm = (Salary  * p1);
         NewSal = Salary + Comm;
         System.out.print("Your Commition is RM" + formatter.format(Comm)); 
         System.out.println(" and your New Salary is RM" + formatter.format(NewSal));

    }
      else if((Salary >  8000) && (Salary <= 15000)){
         Comm = (Salary  * p2);
         NewSal = Salary + Comm;
         System.out.print("Your Commition is RM" + formatter.format(Comm)); 
         System.out.println(" and your New Salary is RM" + formatter.format(NewSal));

    }
     else if((Salary >  15000) && (Salary <= 25000)){
         Comm = (Salary  * p3);
         NewSal = Salary + Comm;
         System.out.print("Your Commition is RM" + formatter.format(Comm)); 
         System.out.println(" and your New Salary is RM" + formatter.format(NewSal));

    }
     else if(Salary >  25000){
         Comm = (Salary  * p4);
         NewSal = Salary + Comm;
         System.out.print("Your Commition is RM" + formatter.format(Comm)); 
         System.out.println(" and your New Salary is RM" + formatter.format(NewSal));

    }
     else{
         System.out.println("Input invalid. Renter Salary");

     }

}

}

您编写了while而不是while。

do {
...
} While (Salary < 0);

正确的是：

do {
...
} while (Salary < 0);

希望这能解决你的问题。
