I have installed jFuzzylite and now I want to use it in java but I could not find any documentation or examples to learn how to use this package please could you kindly tell me what should I do?
As pasaba mentions, you can find examples at: https://github.com/fuzzylite/jfuzzylite/tree/master/examples
They also have a section dedicated to Java: https://www.fuzzylite.com/java/#example
Here's a simple dimmer using it: https://github.com/fuzzylite/jfuzzylite/blob/master/examples/application/src/main/java/com/fuzzylite/examples/SimpleDimmer.java
This is only meant to be a general answer--hopefully someone with experience in the library will be able to provide some additional resources!
