Appending text to TextArea

I have a DoublyLinkedList with displayforward() function which displays the content of my list onto the console. I am using objects to call the displayforward() function from a Router.java file. DoublyLinkedList is another class contained in a separate file. I use ObjectOutputStream inorder to receive the objects.

How do i display the same content onto the TextArea of the Router front end?

TextArea.relpaceRange(String, int, int), TextArea.append(String), TextArea.insert(String, int) and/or new TextArea(String)

InputStream is = socket.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is);

Link pktrecv = (Link) ois.readObject();
Link a=pktrecv;
while(a!=null)
{
String disp="Encoded:"+a.en+"\nPacketNo:"+a.pktno+"\nSour ce:"+a.src+"\nDestination:"+a.dest+"\nData:"+a.dat a+"\nDistance:"+a.dist+"\n";
a=a.next;
jTextArea1.append(disp);
}
pktrecv.displayforward();


pktrecv.displayforward() displays the object content in the console. How do i append the same to the TextArea? Is there a way to directly read from the inputstream and display like the above code?

Does that code not do it?
