/**
 * ConsumerSample接口的使用
 */
public class ConsumerSample
{
    public static void main(String[] args)
    {
        output(s -> System.out.println("Put：" + s));
    }

    public static void output(Consumer<String> consumer)
    {
        String text = "123";
        consumer.accept(text);
    }
}
