Problem
Hello!
I have a problem with my code.
I am trying to store the data that i read in the run method of SocketHandler in a singleton class.
But when i try to display it in the findMeeting method it is empty.
I cant get it out of the run method by returning it eighter because the runmethod returns void.
What is wrong in my code?
Can i get out the data from the run method in another way?
