Java社区进程（JCP）执行委员会的成员Ben Evans认为最急需重构的应用恰好就是最适合进行模块化的应用。如果你已经备受Lava Flow/God Class/Stovepipe System地狱的折磨，而且你的利益相关方明确知道这一点，那么你可能更容易说服他们进行一次完整的底层重构，通过渐进式的努力形成一个完成的模块解决方案（而不是简单重构并迁移至Java 8）是值得去做的。
对特定类型的应用来说，这是很有帮助的。例如，我曾经见到有的电子商务网站具有非常大的堆空间，其中包含了大约40G的字符串数据。Java 9的ompact Strings技术能够将这种类型的内存使用减半。这反过来又会对GC的性能带来积极的影响。对于有些应用来说（这可能就包括大型的Solr安装环境及类似场景），单单这一项收益就值得将运行时升级到Java 9。
这项变更是很重要的，因为相对于Parallel来说，G1会在应用线程上做更多的事情，而Parallel几乎没有在应用线程上做任何事情，它基本上完全依赖GC线程完成所有的内存管理。这意味着切换到G1将会为应用线程带来额外的工作，从而直接影响到应用的性能。 在很多（甚至可以说大多数）场景中，这种额外的性能损耗都不是什么问题。但是，在这方面，我确实也曾经见过从Parallel切换到G1时，有一定比例的工作负载会引起性能的下降。对于这些应用来说，这种性能下降是无法接受的，所以他们无法切换至G1收集器。随着G1成为默认的收集器，这将会影响到升级至Java 9的每个应用。

每个人都知道编程正在成为几乎每个行业的重要组成部分，它对组织的帮助和对大型系统的维护是独一无二的，因此越来越多的人开始了他们的编程旅程。你可以从你觉得合适和方便的任何交互式平台和书籍中学习编程。但是这还不够，我们应该练习更多新的东西。
编码与你的创造力、创新能力密切相关。但很多时候，我们花费大量时间来处理常见问题而忘记了创造力。我不太确定这是否是编码挑战出现的原因，但它们肯定可以帮助你去思考。
我们可以说编程挑战是伟大的：
学习新的做事方式
练习一种新的编程语言
解决遇到的关键问题
保持我们的大脑活跃和集中力
以及玩得开心！
在寻找最好的编程挑战过程中筛选了五个非常好的资源。相信这对你的编程旅途有所帮助，并探索更大的计算机科学领域。
