本文整理了Java中java.util.Objects.compare()方法的一些代码示例，展示了Objects.compare()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。Objects.compare()方法的具体详情如下：
包路径：java.util.Objects
类名称：Objects
方法名：compare

Objects.compare介绍

[英]Returns 0 if a == b, or c.compare(a, b) otherwise. That is, this makes c null-safe.
[中]如果a==b，则返回0，否则返回c.compare（a，b）。也就是说，这使得c null安全。

代码示例

@Override
 public int compare(Operator<?> o1, Operator<?> o2) {
  Long id1 = Long.valueOf(o1.getIdentifier());
  Long id2 = Long.valueOf(o2.getIdentifier());
  int c0 = Objects.compare(o1.getOperatorName(), o2.getOperatorName(), Comparator.naturalOrder());
  if (c0 != 0) {
   return c0;
  }
  return Long.compare(id1, id2);
 }
};
