Here is two example of deleting a file using java.nio.file.
%% Method1
str = fullfile(pwd, 'test1.txt' );
%jpath1 = java.nio.file.Paths.get(str) % not works
jpath1 = java.nio.file.Paths.get(str, javaArray('java.lang.String', 0)); % works
java.nio.file.Files.delete(jpath1)
%% Method2
jpath2 = java.nio.file.Paths.get(pwd, 'test2.txt');
java.nio.file.Files.delete(jpath2)
I've tested in MATLAB R2018b on Windows 10.
As you may know, from R2017b, MATLAB's JVM was changed to Java 8. So, java.nio.file.Files.delete used in MATLAB R2017b ~ R2018b is that of Java 8.

>> Btw, how to determine the success of the operation:
I would simply use "try catch".
try
java.nio.file.Files.delete(jpath2)
catch ME
% When delete was failed, do some error handle
error(ME.message)
end
% When delete was successful
msgbox('Successfully deleted')
