本文整理了Java中com.annimon.stream.Optional.get()方法的一些代码示例，展示了Optional.get()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。Optional.get()方法的具体详情如下：
包路径：com.annimon.stream.Optional
类名称：Optional
方法名：get
[英]Returns an inner value if present, otherwise throws NoSuchElementException. Since 1.2.0 prefer #orElseThrow() method as it has readable name.
[中]如果存在，则返回一个内部值，否则抛出NoTouchElementException。因为1.2.0更喜欢#orelsetrow（）方法，因为它有可读的名称。

@Override
protected boolean matchesSafely(Optional<T> optional, Description mismatchDescription) {

mismatchDescription.appendText("Optional was empty");
return false;
}
final T value = optional.get();
mismatchDescription.appendText("Optional value ");
matcher.describeMismatch(value, mismatchDescription);
return matcher.matches(value);
