输出应该没有0值

Question

我从一定数量的钱中提取硬币数量（数十，五，一，四分之一）。我有这个代码，但输出应该是：10个10比索硬币和1个1比索硬币（没有0个5比索硬币）

    double money = 121;
    int tens = 0;
    int fives = 0;
    int ones = 0;

    while (money !=0) {
        tens = (int) money / 10;
        money = money % 10;
        System.out.printlm(tens + "pcs of 10 peso coin");
        fives = (int) money / 5;
        money = money % 5;
        System.out.printlm(fives + "pcs of 5 peso coin");
        ones = (int) money % 1;
        money = money % 1;
        System.out.printlm(ones + "pcs of 1 peso coin");

    }

输出：

12 pcs of 10 peso coin
0 pcs of 5 peso coin
1 pcs of 1 peso coin

所需的输出：

12 pcs of 10 peso coin
1 pcs of 1 peso coin.

Answer 1

在每个if语句之前添加println条件。

例如：

...
if (tens > 0)
    System.out.println(tens + "pcs of 10 peso coin");
...
if (fives > 0)
    System.out.println(fives + "pcs of 5 peso coin");
...
if (ones > 0)
    System.out.println(ones + "pcs of 1 peso coin");
...
