Yes, its templates.

[android-developers] Re: Is this template in java
Not really. The confusion between Java generics and C++ templates causes more trouble than it explains things. When you come right down to it, the only thing in common is the angle-bracket syntax. It's very misleading to say that Java generics are like C++ templates. For that matter, it's pretty misleading to say that anything in Java is like its counterpart in C++. In Java pointers are called "references" and behave very differently from C++ pointers or references. Garbage collection works differently from destructors. The memory model is different. And so on. Not only that, but almost nothing from 1996 Java applies today. You don't use 'Vector' or 'Hashmap' any more, you have Swing (well, not for Android), a new threading model, generics, 'assert', for:each, enums, ... OMG! The list is HUGE what's missing from a 15-year-old reference. So much that it is essentially useless for a budding Android programmer. > I did a little search on net, but did not see documents explaining the > above. http://lmgtfy.com/?q=Java+tutorial Mine, I am reading a 15-year old book (from a friend) to catch up on Java. I think you have over-emphasized somewhat, it can't be that nothing applies. On second thought, may be I should sue my friend for (may be intentionlly ) misleading me. -- Using Opera's revolutionary email client: http://www.opera.com/mail/ -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

I didn't say that nothing applies, I said that a 1996 book is essentially useless. Does it even mention nested classes, which IIRC didn't exist in Java in 1996? You underestimate the changes. Java 1.1 was pretty much a different language from 1.0, adding inner classes and reflection. 1.2 introduced significant library changes. 1.4 brought in a new keyword, NIO, and other changes. Java 5 once again pretty much reinvented the language, and changed the fundamental memory model. You would do well not to be so dismissive of accurate information.
