Then you need to write it yourself, or use Google to search for samples[^].

Really? You've been here six months, and you haven't worked out that this site doesn't work like that?
If you need specific help with part of some code that you're working on, then we can help. If you just want someone to write some code for you, then you're in the wrong place.
It's even up there at the top of the page:
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'".
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

A homework question! Do your homework yourself. For specific problems, you may ask questions here, but it is up to you to learn to understand how things work, and hence you must try to write some simple programs instead of just copying code!

can anyone please help me with this.. ive created a class for gui..in which the frame consists 3 button and two text fields.. one button is to start server.. another button is to connect server.. and another button is for sending messages.. i have another server class... now how do i link the start server button object to server class inorder to start the server...???
startserver button say B1: gui class
link to server class?? can someone help me please..??

Write an event handler for the button, which creates a server object and starts it. Or is that too obvious?
|
|

You have need to implements ActionListener add actionlistener event like this
JButton btnStartServer = new JButton(" >> Start Server <<");
//Add action listener to button
btnStartServer.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e)
{
//Execute when button is pressed
Server svr=new Server()
svr.startServer();
}
});
In Server class you have to create a startServer() method to do backend processing part.
Like This Example Code:
public void startServer() {
keepGoing = true;
/* create socket server and wait for connection requests */
try
{
// the socket used by the server
ServerSocket serverSocket = new ServerSocket(port);
// infinite loop to wait for connections
while(keepGoing)
{
// format message saying we are waiting
display("Server waiting for Clients on port " + port + ".");
Socket socket = serverSocket.accept(); // accept connection
// if I was asked to stop
if(!keepGoing)
break;
ClientThread t = new ClientThread(socket); // make a thread of it
al.add(t); // save it in the ArrayList
t.start();
}
// I was asked to stop
try {
serverSocket.close();
for(int i = 0; i < al.size(); ++i) {
ClientThread tc = al.get(i);
try {
tc.sInput.close();
tc.sOutput.close();
tc.socket.close();
}
catch(IOException ioE) {
// not much I can do
}
}
}
catch(Exception e) {
display("Exception closing the server and clients: " + e);
}
}
// something went bad
catch (IOException e) {
String msg = sdf.format(new Date()) + " Exception on new ServerSocket: " + e + "\n";
display(msg);
}
}

hi guys please help any body

Hi , I am just trying to reverse all the words of a string at their place only ex if there is a string : "vandana is a good girl" then the out put of the program should be "anadnav is a doog lrig" for that i have created a package to calculate the no of words in the string and also for calculating reverse of a string that pacage is:
package p1;
public class meth
{
public int cal(String s)
{
int wrd=0;
for(int i=0;i<s.length();i++)
{
char c=s.charAt(i);
if(Character.isWhitespace(c))
{
wrd++;
}
}
return wrd+1;
}
public String rev(String b)
{
String p="";
for(int i=0;i<b.length();i++)
{
p=b.charAt(i)+p;
}
return p;
}
}
-----------------------------------------------------------------And the code of my program is :
import p1.*;
import java.io.*;
class rv
{
public static void main(String args[]) throws IOException
{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
System.out.println("Enter your string :");
String s=br.readLine();
meth ob=new meth();
int n=ob.cal(s);
String m="";
while(n>=0)
{
for(int i=0;i<s.lenght();i++)
{
char c=s.charAt(i);
if(Character.isWhitespace(c))
{
String p=s.substring(0,i);
meth ob1=new meth();
String sb=ob1.rev(p);
m=m+" "+sb;
s=s.substring(i+1,s.length());
}
}
n--;
}
System.out.println(m);
}
}
but the problem is my program gives different different out put and it's not working well and i've tired  to understand th problem.

Why make it so complicated? Just read the string and then loop through the characters in reverse order and print each one. You will end up with the string reversed.
|
|
|
|
|
i need to reverse the spelling of words and need not to change their order i.e dog is an animal out should be: god si na lamina .if i use for loop then then the whole string get it'sreverse.
|
|
|
|
|
Then all you need to do is split the string at each wordbreak (e.g. space) and then do the same to each word.
|
|
|
|
|
yeah same i was doing in my code can you please take a look of it

As I suggested earlier, it can be simplified considerably by using the Scanner class, as in the following sample. If you do not wish to use the scanner, then you could write your own class that splits a string into a collection of tokens.
public static void main(String[] args) throws Exception {
Scanner sc = new Scanner("Cotta and Balbus love the sweet voices of the girls");
while (sc.hasNext())
{
String nextWord = sc.next();
char c;
for (int i = nextWord.length() - 1; i > -1; --i)
{
c = nextWord.charAt(i);
System.out.print(c);
}
System.out.print(" ");
}
System.out.println(".");
}

Take a look at the Scanner class[^], which can help in the breaking up of words.
|
|
|
|
|
To get number of words in string u can simply split that string by space.
int[] words = string.split(" ");
int noofwords = words.length;
after getting number of words, loop the words and use reverse logic.
