During Session8 when showing the exercise in DemoSet

You said something like there is only one way to loop through sets, that is with foreach

But it also possible with lambda

cards.forEach((card) -> System.out.println(card));

Which Intellij suggests to replace with method reference

cards.forEach(System.out::println);

Which I'm not sure of the syntax of ❓ but it looks clean and is a one-liner as well

Can you perhaps update the README with some guidelines on contributing so we avoid all the merge conflicts?
e.g. should we append our usernames to packages for specific problems like this:

package sessionX.G_Exercises.ProblemY_USERNAME;

or would it be better to group all our solutions for a specific session in packages like this?

package sessionX.Exercises.USERNAME.ProblemY;
