用戶如何選擇多張門票，然後要求每張門票的總獎金總額？

Question

準備製作一個程序，詢問1到5之間的票數。 然後我需要知道每張票的獎品，要求用戶放置它。 然後做總數的總和。

//kb = keyboard, t = tickets, val = prize, sm = sum tickets 
    Scanner kb = new Scanner(System.in); 
    int t = 0; 
    double val = 0,sm = 0; 

    //this is a loop just for know the ticket number. 
    do { 
     System.out.print("How many tickets do you have?[max 5]"); 

     while(!kb.hasNextInt()){ 
      kb.nextLine(); 
      System.out.println("This is not valid, try again.");     
     } 
     t = kb.nextInt(); 
    } while ((t <= 0 || t >= 6)); 

的問題還是我卡住就在這裏。（它需要的是與）

//With the for I can ask for the value of each ticket 
    for (int i = 1; i<=t ;i++) { 
     System.out.println("Ticket número "+i+" es de:"); 
     val = kb.nextDouble(); 
    } 

如何我總結了diffents每張票的獎金，使總金額？

Answer 1

可以完全除去val，並簡單地添加到直接的總和：

for (int i = 1; i<=t ;i++) { 
    System.out.println("Ticket número "+i+" es de:"); 
    sm += kb.nextDouble(); 
} 

Answer 2

for (int i = 1; i<=t ;i++) { 
    System.out.println("Ticket número "+i+" es de:"); 
    val = kb.nextDouble(); 
    sm = sm + val; 
}
