Im learning Java and I did one exercise that consists in reading the input of the user(name of the network and date of the report) and return the csv that was inputed by the user. I know that the code is far from clean but I dont know how to make it cleaner and is so far working. So Ibasically need help and suggestions on how to write a cleaner code.
