Notice : these algorithms achieved by Java. So,let's going to it. firstly, what is Bubblesort? why we call it in this name? emmmm.... Maybe this image will give you a clear understanding. Bubblesort.jpg I meet so many descriptions,and they all have a…

Scala比较器：Ordered与Ordering

在项目中,我们常常会遇到排序(或比较)需求,比如:对一个Person类 case class Person(name: String, age: Int) { override def toString = { "name: " + name + ", age: " + age } } 按name值逆词典序.age值升序做排序:在Scala中应如何实现呢? 1. 两个特质 Scala提供两个特质(trait)Ordered与Ordering用于比较.其中,Order…

Scala入门之Array

/** * 大数据技术是数据的集合以及对数据集合的操作技术的统称,具体来说: * 1,数据集合:会涉及数据的搜集.存储等,搜集会有很多技术,存储现在比较经典的是使用Hadoop,也有很多情况使用Kafka: * 2,对数据集合的操作技术:目前全球最火爆的是Spark: * * Spark的框架实现语言是Scala,首选的应用程序开发语言也是Scala,所以Scala对集合以及集合操作的支持就至关重要且必须异常强大: * 一个补充说明是:可能是巧合,Spark中对很多数据的操作的算子和Scala中…
