Hi All,
Could somebody explain how new Object[1] and new Object[2] can be used in the below snippet. I understand if new Object(), new Object() was used instead of new Object[1], new Object[2]
public class Practice { public static void main(String args[]) { Object sample [] = {new Object[1], new Object[2]}; } }
Thanks in advance
Anand

After creating a socket, can it be used to send and receive data .
or is it each time i use it for sending or receiving i have to close the socket and create a new one?

i was reading the java buzzwords when i came across the buzzword HIGH PERFORMANCE, it spoke on jit compilers .

what are JIT Compilers and how do they improve the performance in the context of java?

i'm writing a program wherein when i specify the filename it searches in all the available drives for a match.

is their an alternative way to do it , other than by using list() ?

This is my situation.

i'm trying to locate a file in a directory , when i identify a file object as a directory i use the String[] list() method defined in File class but it oftens throws NULLPOINTEREXCEPTION !

if (fileobj.isDirectory())
String s[] = fileobj.list();

it gives me nullpointerexception how come?

Assume i have a package tv, consisting of an interface and two classes class1 and class2 ,all the three stored in separate files within tv
class2 implements the interface and extends class 1

i successfully compiled the interface file and class1.
HOW DO I COMPILE CLASS 2...

could you tell me how to compile the program and to run it,

let's assume its located as the way its mentioned above..

thnx

i think if you set the path variables , you should be able to

but haven't tried it yet

i'm working with windows vista home premium

i have compiled programs where i dont use packages..
so its not my very firs program

How do i compile and run this program...

this is my path where the MyPack folder is..
g:\Program Files\java\jdk1.6.0_01\bin\examples\MyPack
package MyPack; class Balance { String name; double bal; Balance(String n,double b) { name = n; bal =b; } void show() { if(bal<0) System.out.print("-->"); System.out.println(name + ": $ " + bal); } } public class AccountBalance { public static void main(String args[]) { Balance current[] = new Balance[3]; current[0] = new Balance("Anand Divakaran", 1000.50); current[1] = new Balance("Rashmi Divakaran", 2000.50); current[2] = new Balance("Ajay Divakaran", 3000.50); for(int i=0;i<3;i++) current[i].show(); } }
