清单5 显示了 IntSummaryStatistics 类。实际实现包含更多细节(包含用于获取汇总统计数据的 getter),但它的核心是简单的 accept() 和 combine() 方法。 清单5. summarizingInt() 收集器使用的 IntSummaryStatistics 类 public class IntSummaryStatistics implements IntConsumer { private long count; private long sum; ...
usingStringUtils.indexOfDifference(), whichwill return theindex at which the two strings start to differ(in our case, the fourth character of the string). This index can be used toget a substring of the original string, to showwhat is common between the two inputs, in addition to what’...
Reduction parallellizes well because the implementation can operate on subsets of the data in parallel, and then combine the intermediate results to get the final correct answer. (Even if the language had a "parallel for-each" construct, the mutative accumulation approach would still required the...
