Lambda in Java

April 13, 2022 Java

In this post, you will learn how to work with lambda so that you can use that same knowledge and thus evolve.

lambda is used in the creation of anonymous functions and these are so called because they are not declared with the terms of creating a typical function;
in short, lambda’s main objective is to simplify certain and certain functions, and these often do not use the term “return” but rather an expression;

package com.caffeinealgorithm.programminginjava;

import java.util.ArrayList;
import java.util.List;

public class Lambda {
  private List<String> people = new ArrayList<>();

  public void Run() {
    people.add("Nelson Silva");
    people.add("Larissa Fernandes");
    people.add("Pedro Henrique");
    people.add("Raquel Soares");

    // listPeople();

    people.forEach((person) -> System.out.printf("Name: %s\n", person));
  }

  private void listPeople() {
    for (String person : people)
      System.out.printf("Name: %s\n", person);
  }
}

/*
  Name: Nelson Silva
  Name: Larissa Fernandes
  Name: Pedro Henrique
  Name: Raquel Soares
*/
