forEachSystemoutprintln

This line of code is using the forEach method to print out each element in a collection or array. It is using a method reference to System.out.println, which is a method that prints out the argument to the console.

For example, if you had an ArrayList of Strings called "names", you could print out each name in the list with the following code:

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

This would print out each name on a new line in the console.
