I had mistakenly save my class as fileName.text file and tried to rename it with fileName .java but the IntelliJ couldn't recognize it and throws the error saying..
After spending long hours on internet, I found a solution and sharing/keeping here for future reference.
Step 1: Click "File"==> "Settings"
Step 2: Expand "Editor" & Click "File Types"
Step 3: You will see all file types on Right. Navigate to the "Text Files" and Click it
Step 4: You should able to see your file name on the bottom of Registered Patterns (lower box)
Step 5: Remove your file from the Registered Patterns. The problem should solved and let you to rename with fileName.java
Step 6: If not, delete the file from the project and create it again with name fileName

Tips to share a leaflet map with multiple ROIs

zoomed to a particular event or ROI in the map? Yes. Then, how can you share
that map zoomed or centered with ROI/events to your webpage or email as a link? One of the
answers may be set the zoom level and set view near the ROI. Alright, what will you do if you have a map
with multiple ROI/events? Do you make multiple maps with multiple zoom level
and view? You can, but probably not a good idea to do that.
The solution comes here, leaflet-hash.js, solves your needs, it is a JavaScript library
written by Michael Lawrence Evans, which appends the URL hashes to web pages
automatically and the hash changes with Leaflet map on drag or zoom. The hash
consists of map zoom level and latitude/longitude of the center of map
viewport, everything you need to share the map with focused ROI as link in
following simple steps:
