public static void filterTripleA(Collection<String> strings) { strings.removeIf(s -> s.startsWith("aaa")); }

The method filterTripleA removes all strings from the collection that start with the prefix "aaa".

It uses the removeIf method from Java 8+, which takes a predicate (a function that returns a boolean) and removes all elements for which the predicate returns true.

Example of usage:

Collection<String> strings = new ArrayList<>(Arrays.asList("aaaOne", "bbbTwo", "aaaThree", "cccFour"));
filterTripleA(strings);
System.out.println(strings); // Will output [bbbTwo, cccFour]

Here, the lambda s -> s.startsWith("aaa") checks whether the string starts with "aaa" and removes such elements from the collection.
