java8 list filter in 子句 在Java 8中,可以使用`filter()`方法和`IN`子句来对`List`进行筛选。下面是一个示例代码: ```java List<Integer> tmp = Arrays.asList(1,2, 3); List<Integer>tmp1 = Arrays.stream(new Integer[]{1, 2, 3, 4, 5}) .filter(element -> tmp.contains(element)) ....
.listResources("/WEB-INF/classes"); for (WebResource webResource : webResources) { // Skip the META-INF directory from any JARs that have been // expanded in to WEB-INF/classes (sometimes IDEs do this). if ("META-INF".equals(webResource.getName())) { continue; }...
除了filter函数外,Python还提供了列表推导式(List Comprehensions)用于实现类似的功能。列表推导式是另一种强大的工具,用于创建新列表,其中包含满足特定条件的元素。 以下是使用列表推导式完成相同任务的示例: numbers = [1, 3, 5, 7, 9, 10, 11, 12, 13] filtered_numbers = [x for x in numbers if x ...
