我平时用java都是学校里Unix上用，从来不关心版本问题。所以就信口答来是 1.6.
后来他说是 java 6, 加上了generic programming. 我回来一看果然是6，而且对
generic programming不怎么了解. 这个是严重问题吗？他问我的java技术问题我都答
对的。。。。

1.6和6有啥不同
I personally don't think generics is a big deal. More syntactic
sugar to me.

it's just a question too see how familiar you are with the latest java trend.

What if I am unfamiliar with the latest trend. But still answered all his
java knowledge questions correctly (all the questions he asked were
traditional questions, not latest ones).

1.6 is still correct, it's Sun itself that made this versioning mess. The
official version is 6, but it still uses 1.6 internally
generics emgerged since Java 5, it's somewhat similar to C++ template.
shouldn't be a big problem because it's really not a rocket science. but it'
s good to know about it.

I think most recent major language updates are generics and annotation, just
make sure you understand what they are, and how generics work in collection
framework etc

yeah, type "java -version", you'll see
1.6 is internal version, or say, geek versioning, for example, XP is really
5.1, vista is really 6.0
Java SE 6 is the production version

Yeah. I suppose the interviewer should have known that
they are the same.

they just want to check how intimate you are with java ;-)

6和1.6是一样的。如果这个interviewer这么小的地方都抠，哪
我看以后和他工作没有什么好果子。
而且generic是1.5就开始有了。

maybe the statement is a trap waiting for the interviewee
to fight back and claim they are the same. i might do that.

Interviewer应该大气，本来interviewee在心理和气势上就占下风。
用这种方法不能测出interviewee的真实水平。
要用阳谋，不是阴谋。

Interview问这问题，真是谋财害命：回答上来的人，可能一行code都没写过；回答不
上来的人，你也不能disqualify他。还不如：你的咖啡加几块糖？至少还显得实诚。

真正关注java最新发展的，经常看技术文章的，都应该能回答出来这种问题。

Do you really understand what LZ means?
1. He/She answered 1.6 and the interviewer said "should be java 6".
This is very trivial.
2. Generics is added since 1.5, not 1.6

My understanding is that 1.6.0 is the implementation version Sun as a
JDK vendor assigned to specifically the Sun JDK implementation,
while 6 identifies the version of the platform standard, including language
spec, vm spec, core API, etc.

I think IBM uses the same release version.

Yeah, I found a box with ibm jdk after the post. It does print something
to that effect. But then JRockit is currently at like 3.0.3. And OpenJDK
just goes with 6 or 7.
I guess like somebody said above, it's all messed up. ;-)

JRockit is also recognized by my idea as 1.6.0_05
