How do i call a java program in matlab?

Suppose i have this java program with a main class ("Network") and a main method.

Suppose i want to run it from a matlab script, wait for it to finish and then continue the script.

I tried different combinations of solutions i found, none of them works.

o = Net.Network();
% javaclasspath('C:\Users\****\Documents\ProjectFolder\bin\Net');
 % set MATLAB_JAVA=C:\Program Files\Java\jre-9.0.4 c:> "C:\Program Files\MATLAB\R2019a\bin\matlab.exe"
javaaddpath C:\Users\****\Documents\ProjectFolder\bin\Net
javaMethod('main', o, '')

The error i get is as follows:

Error in main (line 6)
o = Network.Network();

Undefined variable "Net" or class "Net.Network".

Or the for one if i use Network as an object

Error using javaMethod
No class Network can be located on the Java class path

Error in main (line 9)
javaMethod('main', o, '')

I have been searching the internet for a solution but couldn't find any, there is just no clear way.

I would aprreciate any help! Thank you
