Create 15B. Write a class based on UML diagram

Create 15A. UML Modeling Language

ArrayList<String> list1 = new ArrayList<String>(List.of("item1", ...));

List, boxed()

Create 13B. Expression Statements Values+++

b = a++ [add, keep initial a]; ++a [add, get new 'a']

catch (FileNotFoundException e) {...}

try (PrintWriter file = new PrintWriter("fileName.txt")) {...}

str.substring equals; str.charAt ==; str.endsWith

map mapToInt mapToDouble collect

objList.stream().filter(obj -> obj.method() == value1).forEach(obj -> ...);

map then filter OR filter (directly)

sum returns int - no need getAsInt()

OptionalInt; chk ArrayList not empty -> then run getAsInt()

OptionalInt; chk ArrayList not empty -> then run getAsInt()

forEach

stringList.stream().forEach(strElement -> System.out.println(strElement));
