Java-EX | Java Common Extension | Plugin library

Stream#empty returns an empty sequential Stream. From this tutorial, I learnt that an empty stream might be useful to avoid null pointer exceptions while callings methods with stream parameters. However, I am not able to think of an example that can help me understand this statement clearly.

Very annoying, gave me around 200 untracked files, every time I delete them they pop back up again. Tried to use lightweight mode and surprisingly it did not work. They files do not have a pattern but it seems like only adding them to .gitignore worked. But I thought there should be a better option.

Not sure if the Java Extension Pack did that or not, but after uninstalling it the problems are still there so I reinstalled them.

I really just wish to get rid of them, don't know if it's also causing some build problems. Been stuck on this for more than a week.

Some posts I have looked at:

Thank you!

Following is stretagy design pattern example take from here. First of all we will create the interface for our strategy, in our case to pay the amount passed as argument.

I am trying to setup my VSCode to get proper code completion in this project: https://github.com/structurizr/java-extensions

I have the Java Extension Pack installed in my VSCode.

But it is not even recognized as a Java project. If I add every single "src" folder via "Add folder to java source path" the Java imports are recognized but the code completion is still not working.

Any hints on what is wrong or what I need to configure in my VSCode to make it work?

Thank you

Before we start allow me to just say that I know that it is possible to integrate Gstreamer into Android natively using C code as done in the Android Tutorials themselves.

This question is not related to simply just getting Gstreamer running on Android but rather running it on Android using the pre-existing native Java wrapper library gst1-java-core alongside JNA inside of Android Studio in a new Native project. However, if Native C code is the only way do let me know if you have tried and failed what I'm trying to do.

Lets begin.

System Information:

• OS: Linux Ubuntu 18.04
• Android Studio Version: 4.1.2
• Java version: 8
• SDK version: 30 (targetting API 21)
• NDK version: 21 (also tried 23)
• Testing Device: Samsung Galaxy Tab S6 Lite (even though haven't gotten there yet)

Process involved setting up a brand new project in Android Studio and choosing Native C++ as the Project Template followed by keeping everything else default including the toolchain. Once the project was built and finished it's Gradle business I did the usual git init and set it up in Git. Following that I downloaded and added the gst1-java-core-1.4.0.jar from the releases page to the "libs/" directly inside the "app/" folder.

Once I had done so I modified the build.gradle file in the app directory to match this Gradle Gist.

This was then naturally followed by a Gradle sync and when that had completed correctly I went to my MainActivity.java and added two lines of code total. First at the top:

It's possible to configure the Beam portable runner with the spark configurations? More precisely, it's possible to configure the spark.driver.host in the Portable Runner?

Currently, we have airflow implemented in a Kubernetes cluster, and aiming to use TensorFlow Extended we need to use Apache beam. For our use case Spark would be the appropriate runner to be used, and as airflow and TensorFlow are coded in python we would need to use the Apache Beam's Portable Runner (https://beam.apache.org/documentation/runners/spark/#portability).

The portable runner creates the spark context inside its container and does not leave space for the driver DNS configuration making the executors inside the worker pods non-communicable to the driver (the job server).

1. Following the beam documentation, the job serer was implemented in the same pod as the airflow to use the local network between these two containers. Job server config:

Hi everyone and thanks for your attention!. Like title says i'm facing a problem trying to connect 3 entities in jpa, where two of them are connected with 3 keys (one Pk and two Fks). i create a simple project on github that works perfectly but i need to change a little bit that scenario. this is the link to the source code:

https://github.com/mcau92/java-exercises-projects/tree/master/com.cauduro.example.jpa/com.cauduro.example.mutlijoin

What i need now is to update the relation between Parent and Child, i need to connect both with 3 columns, the parentID(pid) + GranParentId (gid) + fk2 , what it should look like is something like this:
