Java 1.8 Consumer 消费者

更新时间 2023-05-26 08:57:51

对于 Consumer，我们需要提供入参，用来被消费，如下面这段示例代码：

class Person {
    String firstName;
    String lastName;

    Person() {}

    Person(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }
}

Consumer<Person> greeter = (p) -> System.out.println("Hello, " + p.firstName);
greeter.accept(new Person("Luke", "Skywalker"));
