What is the difference between "architecture-neutral" and "portable"?
(9 answers)
Closed 6 years ago.
I read that "Java is architectural neutral because it have the capacity to read the factor key of one processor into the factor of another processor."
Please explain me in detail the above statement?
Java was designed to support applications on networks.
To enable a Java application to execute anywhere on the network, the compiler generates an architecture-neutral object file format--the compiled code is executable on many processors, given the presence of the Java runtime system

Embedded Prolog Interpreter/Compiler for Java
(13 answers)
Closed 8 years ago.
I hope my question is not a duplicate... I have implemented some rules using Prolog. I would like to ask if there is any way to use these rules in a java application. I do not want to implement everything in java from scratch. I would like to embed the code written in Prolog in a java application. Thanks in advance.
There are various ways. But judging from your question you're looking for a quick solution.
JPL (since i notice a lot of people are using SWI nowadays):

The GNU Prolog library for Java:

SICtus (It comes with syntax examples, etc so it shouldn't be hard for you to use it quickly)

tuProlog (Said to be the easiest to use, beginner friendly)

No. Java does not have direct access to the hardware from pure Java code. You'd have to use native code loaded via JNI calls.

Best Practice: License enforcement for Java Desktop application [closed]

I am creating one Java project.
I want to know how I can create license key for security purposes.
Have you looked into TrueLicense? It's an open source, free software.
I've used it myself to successfully manage licenses on a large scale commercial product. It takes a little work to get it up and running, but it covers all the required bases, and it's hard to beat free.

How to determine if a screensaver is running in Java?
is there any way you can find out if the screensaver is active with java? I've searched the web but the only things I found was very complicated native code... My program is made for windows only.
Java cannot handle system tasks directly.
You should use JNI (Java Native Interface) or JNA (Java Native Access) to do it.
I haven't tried this code, but they claim to answer your question with JNA as Ammar suggested: Screen Saver State.

No, it cannot use multiple cores; however the Eclipse compiler can, if that helps.
