There is a stream method limit in Java 8:

package com.concretepage.util.stream;
import java.util.Arrays;
import java.util.List;
public class LimitDemo {
    public static void main(String[] args) {
        List<String> list = Arrays.asList("AA","BB","CC","DD","EE");    
        list.stream().limit(3).forEach(s->System.out.println(s));
    }        
}

output:

AA
BB
CC

What is the name of analog in Kotlin, or how to do it better by another way?

  • If you view the API reference you can see extension functions on collections, which include the answer. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/index.html, other collection docs are new at https://kotlinlang.org/docs/reference/collections.html – Jayson Minard Feb 10 '16 at 16:44

Based on the documentation:

list.take(3).forEach(::System.out.println)
