Install Java 11 OpenJDK on Windows (a system path issue)

The problem resided in the format of the path line:

1. My path included multiple entries, I was putting Java at the end of the line and the change was not working

2. But when I placed it right at the start of the path line, Java 11 got accepted and started to function alright on my Windows.

For other users facing a similar issue: The root of the problem was that, as Klitos Kyriacou rightly pointed out, my path included other entries that had a word 'java' in their names. When placed before Java 11 in the classpath, those entries were invalidating my adding of the java version.
