0.54 -> hi everyone in this video I will be showing you
how to solve the error a jni error has occurred
6.48 -> please check your installation and try again
so this error occurs in Java as well as spring
11.22 -> boot application in some cases and I'm going
to show how you can solve this in IntelliJ
15.54 -> so this error also has another part like has
been compiled by more recent version so I'll
21.6 -> be showing you four ways how you can solve
this particular error so first way is going
26.28 -> to be downloading the latest version of java
so for doing that you have to just go to like
31.38 -> browser and type Java download you'll
be having Java downloads over here
35.58 -> just click it if you have already downloaded the
latest version of java it's well and good and
40.08 -> I'm also having a solution for that as well so
if you haven't downloaded just go and download
44.16 -> the latest version of java I think the latest
version is 19 and you can also download 17 so
48.96 -> just go select the particular version and click on
Windows or your required operating system and just
53.58 -> click on this installer one you can download
it so after downloading a particular latest
58.02 -> version you need to go to the location where
you have installed which is C program files
63.9 -> it's going to be Java this is a default
location and I am having jdk 17 I will
69.06 -> go with that and need to go to bin just copy this
particular path so this is going to be our second
75.48 -> method which is move up the path in environment
variables just copy the path till bin folder and
81.18 -> you need to go to search and you need to just
type environment variables and click on open
89.46 -> and you'll be getting the system properties dialog
box just click on environment variables again and
94.74 -> need to go to path click on edit so you'll be
getting all the paths over here and I am having
99.24 -> the I've already added the path over here jdk
17 if you haven't added just click on new and
103.86 -> paste the path and click on OK so since I've
already added I am not going to add it now so
109.02 -> after adding the path what you are doing is you
have to move this particular path the top most
113.58 -> all right so you will just select this particular
path jdk 17 bin and need to just click on move up
119.4 -> so that particular path should come at the top
and after only all the remaining Java or all the
124.8 -> remaining paths should come so after removing
it to the up just click on OK everywhere yeah
130.5 -> so this in some cases May fix your error
and even this also doesn't work we need to
135.42 -> change the settings inside our IntelliJ
or eclipse or your IDE so two important
140.16 -> things two places where you would change
one is file you need to go to settings
146.76 -> and in the settings you will be having this build
execution deployment and inside that you will be
153 -> having the build tools Gradle and here you
can see you need to select the particular 17
157.92 -> or the latest version all right they will be like
getting a list if you aren't having you can even
161.94 -> download it from here so just select the latest
version so it's already latest version for me so
166.44 -> I won't disturb anything over here the second
thing where you want to change is file you'll
171 -> be having project structure click it and here in
Project structure you'll be having the project
175.92 -> okay and inside that you will be having the SDK
you need to select the latest version here as well
181.14 -> so be careful both the SDK and that particular
jdk that you've mentioned over there should be
186.18 -> the same versions so just click on apply yeah so
latest version 17 I will click OK here as well so
193.2 -> it'll take some time to load and if I just now
run it I will run and check and after that even
198.24 -> if it doesn't work I will be showing you the
final method so yeah so if I just now run it
206.82 -> so here you can see this time I'm not getting
any error and my application has now started
210.96 -> if you are just compelling a Java program that
will also work most probably and if it doesn't
215.76 -> work now also the final method is going to be
uninstalling all the unnecessary Java versions
221.16 -> that is the old versions that you're having in
your system so for doing that you will just go to
226.44 -> search and type control panel just click on open
232.86 -> and you need to go to programs you'll
be having the programs and features
239.52 -> and you will be getting the list of all the
applications and programs that you have installed
244.14 -> on your system and here you can see we will be
having this Java 8 Java SC development kit 8
250.92 -> Java kit 19 so we will be uninstalling the older
versions of java that we have like we need to just
258.06 -> only have the latest version of java so by doing
this in some cases it may work so try this as well
264.42 -> so just like let me just wait till it loads so it
has loaded now so here you can see I'm having Java
270.96 -> 8 update this is I think the oldest version and 17
and 19 are the latest version so if you're having
275.88 -> any older versions you need to just right click it
and just click on uninstall it will automatically
280.8 -> uninstall from your system so just have the
latest version alone in your system and you
284.4 -> need to like restart your IntelliJ as well just
close and open it and I think this will work so
288.96 -> these are some of the four ways how I solved this
issue and I hope you would have found this video
293.46 -> useful mine's a programming Channel by the way I
have done many videos in C C++ Java python node.js
299.64 -> react JS mongodb MySQL so do check other videos
of my channel subscribe me thanks for watching
