Output to TextArea

Question

This is for a college assignment. I'm trying to output some text
into a GUI TextArea instead of the console. How is this done? I want to execute the method from the GUI, and display the text in a TextArea.
Here is part of the method:
if (roomAvailable == false)
System.out.println("No bedrooms available"); //this to TextArea
}//end then
else
String custName = JOptionPane.showInputDialog(
"Enter name of customer booking bedroom: ");
customerName = custName;
String payName = JOptionPane.showInputDialog(
"Enter name of payee (company name or \"PRIVATE\"): ");
payeeName = payName;
System.out.println(customerName + " is booked into bedroom " + (counter + 6));//this to TextArea
bedrooms[counter--].occupyRoom(customerName, payeeName);
Any help wuold be appreciated.
Thanks

I want to call the method from another
class.Specifically, I am putting the GUI components
and layout in one class, and then calling this method
from here by instantiating an object of its class. My
problem is that the text output is embedded in this
method - how do I chage this output to my TextArea?Make this method return the String that you want to put in the TextArea and then have your GUI class call this method and load the TextArea with the return value as the above poster showed you how to.
