Point(lat, lon) in Polygon from GeoJSON data?

Question

Java

Gentlemen, does anyone have experience with GeoJSON data?
Tell me, I can not find the appropriate function or solution.
I have a file with GeoJSON data, I accept latitude as input, lontitude need to calculate in which polygon this point is located?
Need a java solution.
For NodeJs, the working solution is https://www.npmjs.com/package/geojson-utils#point-... There
are the same and similar libraries for Java, but I can't find how to do the same.
Thank you!

There is an algorithm in one cycle and four checks. Isn't it really so difficult to write your own code, I have other people's ready-made solutions? Or are you a fan of left-pad.
