thank u subodh.

hai, instance var live on the heap. local var live on the stack. does it mean heap lives longer than stack. i dont know what exactly heap and stack means all i know is they are memory parts. please explain

hai kahtir, <?> =< ? extends Object> because of that it will compile. check once again thanks

thanks nitin

can anybody explain me this code String [] sa= { ">ff<", "> f<", ">f<" ">FF<"}; PriorityQueue <String> pq = new PriorityQueue<String>(); for(String s:sa) pq.offer(s); for (String s: sa) System.out.println(pq.poll()+" "); o/p= > f< >FF< >f< >ff< thank u.

hai can anybody explain peek(), poll(), offer() methods thank u

hello seema, i your code what u r doing is 1) i =0 initially u assigned to 1 in for loop which prints 12 to the condition then it exists now the static var i=3 2) now i =0 this is not global var i is local to the for loop then again it prints to the condit 3)now again i=0 this is also local which prints the condition. 4)u r asking to print the value of class global var which i=3. i think this is clear thank u

hai deepak, i think u got it wrong static methods can be inherited by subclass. please checkit out. thank u

hai aneena, sorry to tell u that once u are typing caps JSP and in other program you typed small jsp that make the output change sequence. The collection u used tree is sorted in natural order so caps come first and so on... thanks
