I have a nice and clean interface like so:

I have a parameter where the user of library supplies a lambda expression, usually something like (i,j) => i != j or along the lines of (i,j) => i == j + 2.

I have a parameter where the user of library supplies a lambda expression, usually something like (i,j) => i != j or along the lines of (i,j) => i == j + 2.

This is the below code that I have.

If I want to automate building of an object of my class from some Map or JSON I can use reflection inside some method or constructor of this class. To modify only fields of the method’s object, to which it has access. But in this case, I still need to use field.setAccessible(true) for private fields. As I see it, in this case, I don’t need to use “Illegal Access”. Even more, I’d prefer that compiler ensure my code doesn’t rely on “Illegal Access”. Is there a mechanism of more precise control of which rules reflection breaks? And if not, what is the reason?

i use google guava ClassPath utils to get Classes under specified package, but it returns a strange class which name is end $1 when i debug in idea. i know the anonymous inner class will return the name end with $+number, but the class i try to reflect doesn’t exist anonymous inner class. this is my code:

I am getting an IllegalArgumentException in using newInstance.
