yes. it is .. Single quote. 1-Key right of L.

Java is very nice. I m on east. India. +5.30

fantastic.. It works.. you made my day (night here actually) .. Thanks a lot.

yes, no problem. do you use messenger ?

please do it in c# if you can, I will convert. I did my all possible things.

We both post posted at the same time. haha.

99% done..

for (int i=0;i<first.length;i++)
{
for (int j = 0; j<second.length;j++)
{
sum[i][j] = first[i][j] + second[i][j];
System.out.println(sum[i][j]);
}

But result are showing in vertical manner.. not like matrix way..

poor me... I modified as following ,, and I m done around 90%

same error is showing when i m adding two arrays.. :(

but that line add column values for 2nd row and so on till

Hello. I did this..

Here in bold text.. first[m][n] = Integer.parseInt(br.readLine()); throws ArrayIndexOutOfBoundexception .... When I replace first[m][n] with first[i][j] .. it taking value .. how to rectify this error any suggestion..

Thanks a lot a lot to both of you guys.. You made my day..

I tried that thing earlier but as I declared array as.. int[] value = {2,1,3,6,5} So this line Arrays.sort(value, Collections.reverseOrder()); giving error, red line under value, I don't understand why.. But now I declare array as .. Integer[] value = {2,1,3,6,5} It works....

Please explain why is it happen so.. it bit strange for me. and thanks a lot.

I read the documentation now, I didn't find descending. There is a way by Comparator .. but its lengthy .. Any other way .. please tell.

thanks I did ascending..

public class Main{
public static void main(String[] args) {
int[] value = {2,1,3,6,5};
System.out.println("Unsorted value"); // Print unsorted array.
for (int s : value)
System.out.print(s + " ");
System.out.println("\n");
Arrays.sort(value); // Sort array

    System.out.println("sorted value ascending");       // Print unsorted array.
    for (int s : value)
        System.out.print(s + " ");
    System.out.println("\\n");      
}}

please tell how to do descending...

Hi. I m running this code.

import java.util.*;
public class Main{
public static void main(String[] args) {
int[] value = {2,1,3,6,5};
System.out.println(value); // Print unsorted array.
Arrays.sort(value); // Sort array
System.out.println(value); //
}}

The output is showing.. run: [I@3e25a5 [I@3e25a5 why is it so.. I m confused.. Please help me. Also please tell me how to do in descending order by user input. Collections class will do with List

Thanks.. Sorry to say from my above post regarding this Suppose when I open SQL Server 2005 and Run the Insert Query on a table then that insert should ALSO reflect in SERVER. We don't care if that Data will store in Client side too This will provide inconsistency if 1 client is used to re-enter the data already entered by other client. So I think, continuous Synchronization should be there between databases as soon as any DDL/DML operation will done. How to achieve this ?

Sorry I didn't get you mate. All PCs have Developer Edition [DE]. And application are made by me and my friends. Suppose when I open SQL Server 2005 and Run the Insert Query on a table then that insert should ALSO reflect in SERVER. We don't care if that Data will store in Client side too.
