Problem Accessing ArrayList in another class

[MemberZero]

This is a simple Client-Server socket programming.
Here is my Server Class


import java.net.*;
import java.util.ArrayList;
import java.io.*;

public class Server {
public static ArrayList<MyThread> clients = new ArrayList<MyThread>();

public static void main(String args[]) throws IOException {
ServerSocket s = new ServerSocket(7777);
try {
while (true) {
Socket s1 = s.accept();
MyThread t = new MyThread(s1);
clients.add(t); // adds threads to an ArrayList
System.out.println(clients); // prints the ArrayList(It works and print all threads)
t.start(); //start the thread

}
} catch (SocketException e) {
System.out.println("Error: " + e);
}
}
}


This is a MouseClickeed method in my UI class where I want to access the ArrayList in Server Class

public void mouseClicked(MouseEvent arg0) {
try {

String s = textField.getText();
Client.ClientName = s; \\ gets the string entered and set it as Client Name
System.out.println(Server.clients); \\It's supposed to print Client ArrayList but instead it prints an empty List ([])


}

catch (NullPointerException e1) {
System.out.println("Error: " + e1);
}
}
});

I need help and need to understand why isn't the ArrayList accessible in the UI class !

It looks like the ArrayList is in fact accessible since you're not getting a compilation error. Perhaps you need to figure out instead why the ArrayList is empty.
