How to setup java in windows 10

#java

Recently i was installing JDK on my system, and i did everything from downloading jdk, jre and setting environment variables but when i went to run java code with the command "java MyProg" Error occurred saying something like "JNI error check your installation and try again" so I went on some online research and below is what i found: -->

JRE(JAVA Runtime Environment):it provides us with minimum stuff required for execution of java application/program, NOTE that it is helpful only in execution, We cannot compile or create byte code with it for that you need jdk.

JDK(JAVA Development Kit): it provides us with everything we need for developing java applications/programs, using jdk we can create byte code as it contains javac
during the online surfing I also came to know that for the versions of jdk older than jdk-11 we used to have JRE folder separately but in JDK-11 we don't need that as JRE is the part of JDK-11 link to source
also before doing anything understand the need means, if you are a developer who writes code you need to have compiler, runtime environment and other stuff but if you are a client or just want to run certain application then only thing you require is JRE that's it source
