本文整理了Java中java.util.Calendar.isSet()方法的一些代码示例，展示了Calendar.isSet()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Calendar.isSet()方法的具体详情如下：
包路径：java.util.Calendar
类名称：Calendar
方法名：isSet

Calendar.isSet介绍

[英]Whether the corresponding element in field[] has been set. Initially, these are all false. The first time the fields are computed, these are set to true and remain set even if the data becomes stale: you must check areFieldsSet if you want to know whether the value is up-to-date. Note that isSet is not a safe alternative to accessing this array directly, and will likewise return stale data! The array length is always FIELD_COUNT.
[中]是否已设置字段[]中的对应元素。起初，这些都是错误的。第一次计算字段时，这些字段被设置为true，即使数据过时也保持设置状态：如果要知道值是否为最新值，必须检查arefieldset。请注意，isSet不是直接访问此阵列的安全替代方案，它同样会返回陈旧数据！数组长度始终为字段计数。

      String ms = Integer.toString(n);
      while (ms.length() < 3) {
        ms = '0' + ms; // left 0 paddings.
      }
      buf.append('.');
      buf.append(ms);
