显示多行

Question

我创建了一个基本的订单输入系统，客户将能够放入他们想要的物品和多少个物品。 放入名称和数量后，我希望他们能够选择一个选项来添加其他项目或他们想要的更多项目。 当他们完成添加他们想要的所有物品时，它将显示他们输入的每个物品。

这完全是要通过命令提示符

package stringvars; 

import java.util.Scanner; 

public class NewOrder { 
    public static void main(String[] args) { 

    Scanner user_input = new Scanner(System.in); 
    Scanner in = new Scanner(System.in); 
    String itemName = null; 
    String itemQuantity = null; 
    int continueOrder = 0; 

    if(continueOrder == 0) { 

      System.out.print("What item you would like? "); 
      itemName = user_input.next(); 

      System.out.print("How much of item would you like? "); 
      itemQuantity = user_input.next(); 

      System.out.print("Press 1 to order another item Press to 2 end"); 
      continueOrder = in.nextInt(); 
    } 

    else(continueOrder == 2) { 


    System.out.println("XYZ Company Order"); 
    System.out.println("Here is your order: "); 
    System.out.println(itemQuantity + "of " + itemName); 

    } 
} 

}
