1)如果不是x是"foo"(而不是<> "foo") 2)“OrElse”和“AndAlso”短路(而不是简单的“Or”和“and”，它们的作用不同) 3) Nothing(而不是Null)

很多人认为Java很慢，但我同意一定程度的使用。

Java是戏剧性的。他们为你想做的一件事提供了很多课程。但是你知道灵活性属性XD。

Java一开始很难，但总是很有趣。

当你写一个简单的代码打印“Hello,World!”请不要使用java !XD我相信我是有道理的。

Java是一种混合，所以不要说它是纯粹的面向对象语言。

还有很多，但我只局限于5个XD。谢谢!

以下是我不喜欢Java的一些地方(它不是我最喜欢的语言):

Generics type erasure (i.e. no reified generics) Inability to catch multiple exceptions (of different types) in a single catch block Lack of destructors (finalize() is a very poor substitute) No support for closures or treating functions as data (anonymous inner classes are a very verbose substitute) Checked exceptions in general, or more specifically, making unrecoverable exceptions checked (e.g. SQLException) No language-level support for literal collections No type-inference when constructors of generic classes are called, i.e. the type parameter(s) must be repeated on both sides of the '='

Javascript;

the dynamic binding of "this" is very confusing and dangerous if you don't know exactly what you're doing. a function declaration requires the keyword "function". It's not the typing I object to, it's the reading it when I want to do something slightly clever. Hrm now I think of it maybe that's a plus. Discourages me from doing clever things. As a result of number 2, it's often less code (in terms of characters) to just copy/paste a code segment than to declare it as a function, if it's a fairly short idiom. This unfortunately promotes bad practice, especially in my own code. Javascript makes motions at being a functional language by having first class functions and closures, but there's no way to verify referential transparency in a function, at either runtime or compile time. Without this, some architectures become either risky or bulky. Its fantastically bad reputation, and thus my inability to say "I program in javascript" to anyone without being laughed at.

Common Lisp:

关键词往往太啰嗦。 库支持是可怜的。 在希望更严格地处理内存的操作系统中不能很好地工作。 没有与操作系统交互的良好工具。 “循环”功能没有很好地定义，当然看起来也不像Lispy。

德尔菲:

IDE有点不稳定。 代码洞察有时令人困惑。 调试有时是有bug的。 更新多个项目文件可能会很麻烦。 如果启动时一个或多个包不可用，错误消息会弹出几次。
