Hi, sorry to bump an old thread. But I happened to see ur issue. I'm recently using a Java barcode library to generate code 128, but somehow it didn't work. I think something might go wrong with my code. Can u post some sample code snippet please?  And how to do the settings for it automatically generate on each of the documetn pages? Thanks in advance!

The barcode generator software is a Java library that enables the creation of barcodes in a variety of standard formats that can be displayed as Swing/AWT components. Java barcode packages are provided in convenient JAR files. Each symbology type is combined into a single JAR file with the Applet, Servlet, and Class Library.

I am a developer of java barcode generator,my work is to develope qrcode in java,but i am new to thread safe queue in Java.

I want to implement a queue, that is hit by multiple threads.

This is stack is in a singleton class.

Now, a simple solution is to synchronize this? I assume it would need this as standard? However, I want to prioritize writing to it.

So, write is high priority, read is low priority.

Is this possible?

Ideally writing by multiple threads without synchronizing would be great, if possible.
