when a servlet is deployed in a server and multiple machines sends multiple requests then how the servlet handles those requests..............can anyone explain plz........
[/quote]

if I understand you ques clearly ...

oka servlet vundhi and adhi multiple requests ni ela handle chesthundhi ?? right ?

If so, servlet container every servlet ki oka instance create chesthundhi .. and each request ki oka thread create avthadhi .. then servlet service method will handle requests (like threads) ...

The interface by default extensible cuz it can't be final

[kiran karthik]

Can someone explain

List<MyClass> list = new ArrayList<MyClass>();
ArrayList<MyClass> arrayList = new ArrayList<MyClass>();

which one is more efficient?

More efficient is ArrayList. I would prefer using.

abbbaaa thammudu .... adi extensible kadhuuuuu .... externalize interface adiiiii.....


assalu adi enti anteee ... it is a kind of serialization ..... mari already serialization undi kadha gidhi endhuku antavu kadhaa ....


serialization sesthy .... JVM aaa object state ni byte gaa write chesthadi ....... geeda problem endhi anteee current object lo unna anni variables , objects , including super classes serialization aithai .... like nuvvu oka car object lo car model , car miles , and licence number serialazation chedam anukunav ..... kani java serialazation process car ki unna engine , tyrs , dikki gitlaa ani serialze chesthadi ..... so adi performance problem .......


ippudu exrernalize interface use chesthy , u can choose what feilds to serialize .... nuvvu 2 methods override cheyali writeExternal and readExternal .... vitini use chesi u can choose which feilds to serialize

below one is better programming model ..... choose always interface based programming ....

[b]List<MyClass> list = new ArrayList<MyClass>(); [/b]

May be coz we can use all the methods available in the particular Interface List.
