Exploring the Basics of Java 8 Object To Map
When it comes to “Java 8 Object To Map”, there are a few things you need to know. First, it’s a feature introduced in Java 8 that allows you to convert objects to maps and vice versa. This feature is available in the java.util.stream.Collectors class.
Converting Objects to Maps
Let’s say you have a list of objects, and you want to convert it to a map. With “Java 8 Object To Map”, you can achieve this in just a few lines of code. Here’s an example:
Listpeople = new ArrayList<>(); people.add(new Person("John", 25)); people.add(new Person("Jane", 30)); people.add(new Person("Mike", 35)); Map peopleMap = people.stream() .collect(Collectors.toMap(Person::getName, Person::getAge));
This code creates a list of Person objects and converts it to a map of names and ages. As you can see, it’s straightforward and easy to understand.
Converting Maps to Objects
