Question

我是java的新手，我坚持使用非常简单的代码。我已经添加了while条件，但eclipse仍然要求它。

错误：

语法错误，插入while (Expression);以完成BlockStatements

代码：

 package assignment517;
 import java.util.Scanner;

 public class Products {
   public static void main(String[] args) {
     // TODO Auto-generated method stub 
     do{
       Scanner input = new Scanner(System.in);
       System.out.print("Enter the number of product");
       int numberOfProduct=input.nextInt();
       System.out.print("Enter the products sold");
       int productsSold=input.nextInt();

       double pprice = 1.0;

       switch(numberOfProduct){ 
         case 1: {
           System.out.print("Price of total products sold");
           System.out.print (pprice= 2.98*productsSold);
           break;
         }

         case 2: {
           System.out.print("Price of total products sold");        
           System.out.print(pprice= 4.50*productsSold);
           break;
         }

         case 3: {
           System.out.print("Price of total products sold");
           System.out.print(pprice= 9.98*productsSold);
           break;
         }

         case 4: {
           System.out.print("Price of total products sold");
           System.out.print(pprice= 4.49*productsSold);
           break;
         }

         case 5:{
           System.out.print("Price of total products sold");
           System.out.print(pprice= 6.87*productsSold);
           break;
         }

         default:{
           System.out.print("invalid value");
         }

       }while(numberOfProduct !=6);
     }
  }

您的while放错地方了 - 它应该在}的关闭do之后，而不是switch。请注意，由于它依赖于numberOfProduct变量，因此您需要将其定义移到do-while循环之外。
