I am trying to use the JNativeHook library in my project so I can get the global keystrokes, but I am not sure how to import or install the library in my project. I need help on importing the library to my project. I need simple steps to install the library as I am new to java programming.
With Eclipse, right click on project > properties > Java Build Path > Libraries > Add JARs... Then add jnativehook.jar

I cannot create Java record class in IntelliJ, and I could not find the option to enable it.
Is there a way to enable it?
Make sure you have an updated version of the IntelliJ IDEA (2020.1 or later);
Go to the Project Structure and set your Project Language Level to Java 14 (remember, as well, to set Java 14 as your Project SDK, if not done yet).
See more here.

After downloading the code required for the book, I extracted the file in C: and whenever I try to open the project in NetBeans it doesn't read the file as a project. It sees it as a normal file.
I found a similar question asked about Eclipse, and the answer wasn't clear. I'm hoping I can get a step by step beginner friendly answer.
Thanks.
Edit: I'm using NetBeans IDE 8.2, the code I downloaded was from this link: https://github.com/BruceEckel/TIJ4-code
I simply clicked File -> Open project -> unzipped file
This is how I typically open any project I download.
IDE's have project files which are different from language files such as java or c.
You can probably just create a new project and then pull that java file into the project through copy-paste or moving it through your computer's directory.

this is my projects's hierarchy
I'm currently doing a project, and one of the function is to play videos.
So, i'm using dsj.jar to play the videos..
It works perfectly when running using eclipse, but after export it into .jar,
the video won't play.
So, i guess, i don't have problem in defining the resource path or import the jar
(built path -> add external jar).
But why the video won't play after I export it into runnable jar?
If you run your jar outside eclipse, you need to specify the classpath, i.e. the jars that your jar depends on.

I'm not able to find out why does the manually importing any project even a very small app like "hello World" is not importing successfully.
I receive lots of compilation errors saying that name is not resolved.
Basically name could be anything, it could be variable, it could be package or even class name, it can't be resolved by eclipse.
But when i made explicitly that project into eclipse - it works fine? please help me out?
Try to add new system library, this is like common where we get errors.

Hi I try to create a simple Map project in Eclipse, when I run my project from Eclipse to device, my map can shown, but when my project was compiled as .apk my map not shown in my Fragment. How to solve my problem?
If you signed your APK with a different keystore you may not have registered both your debug and release keystore on the Google Developer Console.
Check out this link for details on how to add both SHA1 fingerprints (debug and release) so that your API Key works on both.
