Java, assert file equals
equals, java, performance
Solution
Not sure what the objection to 3rd party libraries is... no need to re-invent the wheel.
I've found the open-source and widely used apache.commons.io method `FileUtils.contentEquals(file1, file2)` is pretty good - here's the javadoc.
Problem
I want assert to files using char by char comparation. What the best way to do this? Without 3rd part libraries. Which file-reader is most performance for this?
