List
List<E>
(mainly ArrayList
and LinkedList
) is the most used interface in Java to work with ordered collections of elements. Its efficiency stands out even more when combined with lambda expressions, allowing concise and efficient data manipulation.
Let’s look at some examples:
<code class="language-java">List<String> nomes = Arrays.asList("Ana", "Carlos", "Bruna"); // Iteração com forEach e lambda nomes.forEach(nome -> System.out.println(nome)); // Remoção de elementos com removeIf e lambda nomes.removeIf(nome -> nome.startsWith("C")); System.out.println(nomes); // Saída: [Ana, Bruna] // Transformação de elementos com replaceAll e lambda nomes.replaceAll(nome -> nome.toUpperCase()); System.out.println(nomes); // Saída: [ANA, BRUNA]</code>
As demonstrated, forEach
, removeIf
and replaceAll
simplify common operations on lists, making the code cleaner and more readable through the use of lambdas. This combination is ideal for tasks such as filtering, transforming and iterating elements.
