Interfaces must contain methods which uses the classes object as a parameter. Look at ActionListener Interface, in this interface you will get actionPerformed method. This method uses ActionEvent object. All the backend work is done by ActionEvent object. You must implement your interface in a manner like this.

Its a simple project but with network understanding. For Lan Monitering you must be connected as a gateway so you can map p.c's which are attached with network. For starter search api's which can help you getting connected p,c information. Please watch these api's

I remember i used to initialize the head with the first linked list address in C/C++ language. But in java there are no addresses concept, Jvm handle pointer for you. So instead of making traditional linked list in java like c/c++ , why dont u try something new. Also LinkedList classes are available in java, then why are you re-inventing the wheel.

How can i ready physical layer of osi through c language? Is there any other language to perfom this task?

`select s.sname as stationname , sum(di.quantity) as quantity from demand_information di, demand d, company c , station s where s.sno = d.sno(+) and di.demandno = d.demandno and d.cno = c.cno and c.cname = $P{companyname} and to_char(d.demanddate,'MM-yyyy') = $P{gdate} and di.pno = (select pno from products where productname = $P{productname}) group by s.sname'

Following is my query ... i want to print all the stations , so i am using s,sno =+ d.sno ( left outer join) on station but nothing is working right... Please give it a view. Thank you.

I want to assigne value to string array but i dont know the size of the array from start... Is there any way to do it
Programatically

for(int i=0 ; i < unkownSize; i++)

Thank you for giving time.

This error simply means you havnt initialized object. Paste the complete error message so we can clear your problem

Its not a new question, i already searched many forums and found many answers but the builders i found arent able to compete with builder of vb.net and c#.net, so i thought to take some decision from some experience people , please give me some of your suggestions. I already worked on code alot , now i want to work alot faster.

http://www.daniweb.com/software-development/java/threads/99132/starting-java-java-tutorials-resources-faq
On top of java forum this link is mentioned. Its nicely discussed thread with all suggestion and help.

Thank u v much, i found the solution myself....

I simply use setValueAt function in the default table model.

I am trying to make a excel sheet like structure, in which for each row when one cell is updated then it will update the other cell with formula... I think many people are familiar with excel sheet usage and formula... I just debug my code , it seems though table changed is called again and again when table.setvalue is called.... i havnt found any solution yet , so please kindly give me some of your kind suggestions.

Sorry, i cant understand this new forum... so cant arrange them... I will learn with time.

I am setting a table row manually.... its just for checking purpose , i have 10 rows and 10 columns but still i am getting this error, please help me to resolve it....

I dont know what is ur purpose of creating a user with admin privilege without root permission. But creating a user with root privilage will be a bad idea... create a simple user and switch to root by using "su" command, its safier then creating over heads.

Look creating a web browser isnt that simple, u can use already deployed project to understand the working or extend them like http://lobobrowser.org/java-browser.jsp. If you want to open URL in a webbrowser like firefox or IE then use JDESKTOP Api. Hope this Help...

I am using jasper report (ireport for designing). I want help regarding to set relative path of the images and jar files for report... As the jasper report pick up the absolute path so it create problem when the drive is changed or even pc is changed... Kindly please help me solving this problem. I m making desktop application.

are u using two different pc's?

You need an array of integer to place the number's which are use for division. Like

int dividend[] = {2,5};

Then you need a while loop

while(i<dividend.length)
if(start % a[i])

I have checked your code... Look at this line

for(start = start ; start <= end; start++){

You have done a blunder , try int i instead of start. and i want you to figure it out why.

First of All "rs.getString(indexno)" is treated as an string , it has no effect... You must write rs.getString(indexno). and is this complete code?

Problem lies in the column name, which you are using in the rs.getString() method. Correct your column name.

Just write your own function, it will be overwritten automatically. Search the necessary function which you want to edit.

Seems like you are working on bydefault class of JBUTTON, you can customize classes in java according to your needs...

AS JBUTTON implements imageobserver class you better check you desired function and overwrite it according to your own needs.

Swap these two line.

employee =Integer.parseInt(JOptionPane.showInputDialog(null,"Enter number of employees: "));
int size[]= new int[employee];

Check Line 15....... This is creating infinite Loop for you.

Nothing works, I simply bought a new switch to forward the connection............ and it worked... thank you all.

it isnt wireless , it is wired... I am using Xp sp2, and have a static ip too with all correct parameter's.

I have a laptop, i have pluged it with a wire which is near to the router it worked but when i connected it a wire which is 60m away from router it says "UN-identified network", please help me to resolve it.

There are two solutions for this ,
1) SERVER BASED (LEARN TO USE SOCKETS)
2) WEB BASED (LEARN TO USE JAVA EE)

Well count any not null column in the table. Then the below code will help u.

if(resultset.next())
long count = Parse to Long (resultset.getString("columnname"));

http://stackoverflow.com/questions/50532/how-do-i-format-a-number-in-java
You need format class in java

Convert Write String to a function which takes int as a parameter and returns the String to execute.
Let me explain more

method String writeString(int)
{
return Here is ur code
}

Declare a variable locally increment it and send to function.

Its too simple
String.split("(Space)") // Leave a space here ... Second split function returns a String array so u need a String array to carry the values.... Like

String a[] = String.Split(" ");

And then print them or use them for ur logic...

Hope this Help....

what java have to do with this? If you want to optimize sound then use a algorithem to optimize the sound.

I think you want to get the current salary of the user when u change the combo box value, try read this article
http://docs.oracle.com/javase/tutorial/uiswing/events/itemlistener.html
Make a method which on change or selected values in combo box search the file for the specified value and place it on the textfield.

Hope this helps....
