要求用戶輸入1元,5元,10元的張數,以元為單位輸出所有錢的總和的編程怎麽寫

public class test{

public static void main(String[] args) {

int yiYuan,wuYuyan,shiYuan,total;

System.out.print("請輸入壹元的張數：");

yiYuan = new Scanner(System.in).nextInt();

while(yiYuan < 0){

System.out.println("數量必須大於0，請重新輸入！");

System.out.println("");

System.out.print("請輸入壹元的張數：");

yiYuan = new Scanner(System.in).nextInt();

}

System.out.print("請輸入五元的張數：");

wuYuyan = new Scanner(System.in).nextInt();

while(wuYuyan < 0){

System.out.println("數量必須大於0，請重新輸入！");

System.out.println("");

System.out.print("請輸入五元的張數：");

wuYuyan = new Scanner(System.in).nextInt();

}

System.out.print("請輸入十元的張數：");

shiYuan = new Scanner(System.in).nextInt();

while(shiYuan < 0){

System.out.println("數量必須大於0，請重新輸入！");

System.out.println("");

System.out.print("請輸入十元的張數：");

shiYuan = new Scanner(System.in).nextInt();

}

total = yiYuan + 5 * wuYuyan + 10 * shiYuan;

System.out.println("妳輸入的壹元有：" + yiYuan +"張，五元有："

+ wuYuyan +"張,十元有：" + shiYuan + "張，總金額是：" + total +"元.");

}

}
