Posted by kll on February 18 2025 21:39:07
i used JAVA only indirectly like with
PROCESSING
or first
ARDUINO IDE
Extended Blog
but now i want setup my win 10 PC to do some JAVA APP development.

i do have
VSCode installed VSCode
that can be used for JAVA
java-tutorial
get JavaCodingPack-0.4.2.exe
and help install
OpenJDK17U-jdk_x64_windows_hotspot_17.0.14_7.msi ( yes choose older version )

now make your first Project

-b- VSCode run > ( search field click down 'Schow and run Commands' click )
JAVA create JAVA Project click
no build tools click
give directory and example project is setup
run that App.java file and see in terminal:

LINUX:
on linux i start from opening VSCode
open EXTENSIONs
search
EXTENSION PACK for JAVA
install

on linux terminal
sudo apt install -y openjdk-17-jre-headless
reboot




now to make it a executable first need:
Video Tutorial

https://launch4j.sourceforge.net/
make launch4j.config
run and get .exe
( but still need JRE installed )


so even now we have a windows .exe, question is how to ship it?
following that same video tutorial:

install / need:
7-zip www.7-zip.org/
+ pack JRE and App.exe

7-zip SFX sourceforge.net/projects/sfx-maker/
+ run as Administrator
+ point to that 7-zip ( of JRE and App.exe )
+ add a Task to run program at start ( and point to App.exe )
+ temporary extraction path AND NOT allow user to change path
so it just starts after extraction
