我的时钟代码停止在Ten O＆＃39;时钟

Question

我的时钟代码每隔一小时工作一次，除了10点钟。时钟。在每隔一个小时，每当秒为60时，它会将分钟增加1，但是在10分钟时，它会增加1分钟。时钟，出于某种原因，每当秒数为10时，它会将分钟增加1.我不知道我做错了什么。请帮忙！

首先，你的代码很乱。

您需要学习如何更有效地使用条件，还要了解格式化。

您可以轻松添加＆＃39; 0＆＃39;在任何数字之前，如果它不是一个＆＃39; 2位数字＆＃39;。

System.out.println(String.format("%02d %02d %02d", hour, minute, second));

你的代码在10点钟没有工作。时钟，因为你所有的条件都是＆amp;小时＆gt; 10＆＃39;或者＆＃39;小时＆lt; 10＆＃39;，hour == 10时，这两个都是假的。
