本文整理了Java中java.lang.Double.compare()方法的一些代码示例，展示了Double.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。Double.compare()方法的具体详情如下：
包路径：java.lang.Double
类名称：Double
方法名：compare
[英]Compares the two specified double values. There are two special cases:
代码示例来源：origin: google/guava
/**
* Compares the two specified {@code double} values. The sign of the value returned is the same as
* that of <code>((Double) a).{@linkplain Double#compareTo compareTo}(b)</code>. As with that
* method, {@code NaN} is treated as greater than all other values, and {@code 0.0 > -0.0}.
*
* <p><b>Note:</b> this method simply delegates to the JDK method {@link Double#compare}. It is
* provided for consistency with the other primitive types, whose compare methods were not added
* to the JDK until JDK 7.
*
* @param a the first {@code double} to compare
* @param b the second {@code double} to compare
* @return a negative value if {@code a} is less than {@code b}; a positive value if {@code a} is
* greater than {@code b}; or zero if they are equal
