In ‘Variable name’ field,
put the value ‘Path’
and in ‘Variable value’ field
value would be %JAVA_HOME%\bin

reference to the environmental variable we
have set previously,, and here the value
would be %JAVA_HOME% followed by \bin
(don’t skip or ignore the backslash ‘\’)

Setting JDK Environmental Variables
Environmental Variable  classpath
In ‘Variable name’ field,
put the value ‘classpath’
The value field would actually contain three
values separated by semicolon ‘;’ and they are:
. (a dot), JDK library path and JRE library path
Thus the value would be like
.;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
(it’s like dot ‘.’ followed by semicolon ‘;’ then
%JAVA_HOME% followed by \lib followed by
another semicolor ‘;’ then %JAVA_HOME%
followed by \jre\lib (note backslashes carefully)
Then click on OK button
