Answer 3

Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%\bin

Answer 5

Its still the same concept, you'll need to setup path variable so that windows is aware of the java executable and u can run it from command prompt conveniently

Details from the java's own page: https://java.com/en/download/help/path.xml That article applies to: •Platform(s): Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, Windows 8, Windows 7, Vista, Windows XP, Windows 10

Answer 6

if you have any version problems (javac -version=15.0.1, java -version=1.8.0)
then delete these in your system variable path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\Common Files\Oracle\Java\javapath

then if you're using java 15
path = C:\Program Files\Java\jdk-15.0.1\bin
is enough

if you're using java 8
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_271
path = %JAVA_HOME%\bin
