Accessing DataOutputStream

I have a class named Class1 and it has a boolean method isClientConnection(InetAddress address, int serverPort) and code is
boolean isClientConnection(InetAddress address, int serverPort) {
//Here address is localhost and serverPort is 4093
InetAddress serverName = address;
int port = serverPort;
try {
System.out.println("Connecting to " + serverName
+ " on port " + port);
client = new Socket(serverName, port);
System.out.println("Just connected to "+ client.getRemoteSocketAddress());
outToServer = client.getOutputStream();
out = new DataOutputStream(outToServer);
out.writeUTF("OIE Raju " + client.getLocalSocketAddress());
out.flush();
return true;
} catch (IOException e) {
return false;
}
}

what i want is that i want to access out object from another class named Class2.
I tried this under Class2 but didnt work:

Class1 c1=new Class1();
c1.out.writeBytes("hellowwww");

How can i solve it ???? Help !!

Please explain. You need to show the definition of Class1 where out is defined and given a value.

Oh sorry for not providing it. I have made them global variable as :
Socket client;
OutputStream outToServer;
DataOutputStream out;

Are the variables local to a method or are they class variables? Are they public or private?

Please post the full text of any error messages.

under class2.java, i write :

private void sendButtonActionPerformed(java.awt.event.ActionEve nt evt) {
Class1 c1=new Class1();
try {
mf.out.writeUTF("Hellooooooooo");
} catch (IOException ex) {
System.out.println("unable to send message");
}

but it didnt work.
Helllooooooooo is not written to the serverPort (4093) that i defined in Class1.
Sorry for my weak English.

Is mf.out.writeUTF("Helloooooooo") wrong ??

What is written?

You will have to provide a small, complete program that compiles and executes to test with. A SSCCE

That code there instantiates c1 and then doesn't use it.
How does the call to writeUTF() have anything to do with that Class1 object?
