Control Flow

Loops

For Loop

for(int i = 0; i < 10; i++) {
    // do something
}

List<String> myStrings = new ArrayList<>(List.of("hello", "world"));
for (String s : myStrings) {
    // do something
}
for (var s : myStrings) {
    // do something
}

Interable Interfaces

Many collections implement the Iterable interface, which has a method for each.

List<String> words = new ArrayList<>(List.of("hello", "world"));
words.forEach((s) -> System.out.println(s));
