cars_aircraft table id aircraft_name home_base_address alternate_base_airport 1 MIG 20 77 80 2 MIG 30 80 77 cars_airport table id airport_city airport_name 1 mumbai CST 2 pune PIA

id is foreign key for second table,I need aircraft_name,airport_name as a result
for airport_city="mumbai"

Condition is that in search not only searched city's aircraft should
come as well as closest city's aircraft should also come.

i.e closest city of mumbai is pune(based on alternative_base_airport
value of mumbai which is home_base_address of pune)

so when user provide argument airport_city="mumbai"

then result should be like that

airport_name aircraft_name CST MIG20 PIA MIG30

Yes , Luca I passed that last year but because of unavailability of proper study guide it took long time to feel confident to write ocjp 7 exam.

Hi
Luca, i passed exam with 81 %.

I got a link related to it.
Java EE 7 Job Task Analysis Survey Announcement – Participants Needed

Hi

Oracles released java EE 7 on june 12, 2013j. Is there any news for ocewcd 7 exam ? ,Should i wait for that new exam or i should write ocewcd 6 exam ?

Thank you

Thank you very much I scheduled my exam on Friday.I hope i would get at least passing marks.

Thank you for reply Did you get questions on each chapter ? which chapters have more weightage ?

Yes that' right

I think it is String[] args=new String[0]; but don't know how enhanced work with this ,anyways thank you.

Ulf Dittmer wrote:Because your loop ending condition is incorrect. You're accessing the 0-th element even though there is no such an element.

Why enhanced for statement doesn't throw runtime error ? and args is not null then what it refers ? thank you

class Test { public static void main(String[] args) { System.out.println(args==null); for(String s:args) System.out.println(s); for(int i=0;i<=args.length;i++) System.out.println(args[i]); } }
false
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

I ran this code thru IDE.My questions are 1) args is not null then what object it has ? 2) basic for loop causes runtime error then why enhanced for loop doesn't ?
at TestArray.main(TestArray.java:11)

If one moderator of the Forum think that my experience can be useful for everybody, you can stick this post ;)

Thanks!

Congrats great effort. There should be cow for you.

could you tell me difficulty of questions ?

oh got it , just passing reference.

I thought i have created three different threads and they use their own lock for synchronization and operating on their own StringBuffer object rather than a shared object. sb is not shared object , each class object has their own.

They are not in loop.
