编程的艺术：Java的VS C＃

问题描述

在我的整个大学生涯我用Java来code项目，直到我开始工作，这是我不得不深入到C＃的境界。虽然NET库是相当广泛的我不禁感到有东西在C＃中失踪相比，Java的。我想知道，如果Java是比任何C＃，反​​之亦然从专家那里更好。你会用什么来开发既复杂又相当琐碎的应用程序？有哪些优点和使用这些技术，2比其他的缺点是什么？

Throughout my university career I used Java to code projects until I started working which is where I had to delve into the C# realm. Though the .Net library is fairly extensive I can't help but feel that there is something missing in C# as compared to Java. I would like to know if Java is any better than C# or vice versa from the experts out there. What would you use to develop both complex and fairly trivial applications? What are some of the advantages and disadvantages of using these 2 technologies over the other?

推荐答案

多年来，C＃在玩追赶与Java。与C＃/结束。.NET 3.0 / 3.5，现在它的（大部分）的其他方式。什么C＃Java那样呢？

For years C# was playing catchup with Java. That ended with C#/.Net 3.0/3.5 and now it's (mostly) the other way around. What does C# have that Java doesn't?

• 瓶盖;


• 运行仿制药;


• 原始类型的泛型（这个排序一百万个整数VS百万Integer对象名单基准揭示的改善3倍）;


• 代表;


• 活动;


• LINQ


• 扩展方法;


• 一流的性能;


• 运算符重载;


• 索引器;


• 匿名类型;


• 防爆pression树木;


• 使用块;


• 否检查异常。万岁！


• 十进制类型;


• 作为C＃4.0：在动态类型，它基本上是。

• Closures;
• Runtime generics;
• Generics of primitive types (benchmarks of this sorting a list of a million ints vs a million Integer objects have revealed a factor of 3 improvement);
• Delegates;
• Events;
• LINQ;
• Extension methods;
• First-class properties;
• Operator overloading;
• Indexers;
• Anonymous types;
• Expression trees;
• Using blocks;
• No checked exceptions. Hooray!
• Decimal type;
• As of C# 4.0: the dynamic type, which is basically duck typing.

和Java有：

• WAY ，更好的方式枚举。 C＃枚举只是INTS有条纹画下侧。 Java的枚举治疗与行为的对象是远远优于（恕我直言）;


• 我知道这将是有争议的：更好的IDE ，特别是在code重构，其中的Visual Studio（没有ReSharper的）仍然远远落后的IntelliJ，Eclipse和甚至可能NetBeans的境界;


• 它运行在Linux上。单尽管如此，Windows是目前的.Net最大的阿喀琉斯之踵（恕我直言）;


• 这是免费的。 Java的6 + Glassfish的Eclipse的+ + LINUX成本，你什么都没有。现在做同样与.net + IIS + VS + R＃+的Windows Server ...;


• 恕我直言，Java 5的并发utils软件包仍优于任何形式的，我已经看到在C＃中迄今为止并发工具;和


• 值得注意的是更多的开源项目，但铅正在迅速减少。

• WAY, way better enums. C# enums are just ints with a stripe painted down the side. Java treating enums as objects with behaviour is far superior (imho);
• I know this will be controversial: better IDEs, particularly in the realm of code refactoring where Visual Studio (without Resharper) is still lagging far behind Intellij, Eclipse and possibly even Netbeans;
• It runs on Linux. Mono notwithstanding, Windows is by far .Net's biggest achilles heel (imho);
• It's free. Java 6 + Glassfish + Eclipse + Linux costs you... nothing. Now do the same with .Net + IIS + VS + R# + Windows Server...;
• IMHO the Java 5 concurrency utils package is still superior to any sort of concurrency tools that I've seen in C# to date; and
• Significantly more open source projects but that lead is being rapidly diminished.

而可悲的是这就是所有我能想到的在Java列蜱。

And sadly that's about all I can think of for ticks in the Java column.
