Is there a function similar to the Map function in Arduino for Java?
I need to map a range of values to another range of values, so I was wondering if there was something similar to it in Java, I've been searching but I only get the Java's Map function.

The map() function is a method in the Stream class that represents a functional programming concept. In simple words, the map() is used to transform one object into other by applying a function. That's why the Stream. map(Function mapper) takes a function as an argument.
The map() function provided by the Arduino language allows you to map that range of values to a different range.
map() applies function to each item in iterable in a loop and returns a new iterator that yields transformed items on demand. function can be any Python function that takes a number of arguments equal to the number of iterables you pass to map() .
The code of map() from Arduino's library is this:
long map(long x, long in_min, long in_max, long out_min, long out_max)
{
return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
}
This will work in Java just the same - no real magic. But standard Java has nothing predefined like this.
