i have my applet made and the code all wrote for it..
i have a separate peice of code that allows info to be added to simulate a print queue on the applet...
when i add all the info in and hit the display button to display the details of the queue in the display box on the applet it is only showing one result.. if i enter 3 sets of data it only shows the middle set.. i need it to show all the data..

heres the code for the main display method..
public String displayQueueApplet()
// Pointer to access the queue
QueueNode nextQueueNode = new QueueNode();

String statement;

// Test if queue is empty
if (start == null)
statement = "\n\nThe queue is empty!";
return statement;
// Start at the front of the queue
nextQueueNode = start;

// Output the next data value in the queue
statement = "\nQueue Contains:\n";

// Loop through all the details in queue
while (nextQueueNode != null)
// Update the pointer
nextQueueNode =;

// Output the next data value in the queue
statement = "\nQueue Contains:\n" + "Document Name: " + nextQueueNode.string1 + "\n" + "Document Owner: " + nextQueueNode.string2 + "\n" + "Document Size(KB): " + nextQueueNode.number +"\n";
return statement;
return statement;

and heres the code that calls it for the applet
// Test for Display Queue button
else if (arg.equals("Display Queue"))

Welcome to the JavaRanch, Stephen.
Please do not post the same question to more than one forum. Most everyone here reads more than one forum so you aren't increasing your audience, and the community may duplicate effort answering your question twice.
