How to compare equality of lists of arrays with modern Java?

Question

I have two lists of arrays.

How do I easily compare equality of these with Java 8 and its features, without using external libraries? I am looking for a \"bett

Answer 1

using zip (which originates from lambda b93) function from https://stackoverflow.com/a/23529010/755183, code could look like:

boolean match = a.size() == b.size() && 
                zip(a.stream(), b.stream(), Arrays::deepEquals).
                allMatch(equal -> equal)

update

in order to check size of arrays first and then content this could be a solution to consider

final boolean match = a.size() == b.size() 
                   && zip(a.stream(), b.stream(), (as, bs) -> as.length == bs.length).
                      allMatch(equal -> equal)
                   && zip(a.stream(), b.stream(), Arrays::deepEquals).
                      allMatch(equal -> equal);
