import java.util.ArrayList; import java.util.Arrays; import java.util.List; public class Main { public static void main(String[] args) { List arr = asList("one", "two", "three"); System.out.println(arr); List firstTwo = pickTwo("one", "two", "three"); System.out.println(firstTwo); } static List pickTwo(K k1, K k2, K k3) { return asList(k1, k2); } @SafeVarargs static List asList(T... objs) { return new ArrayList(Arrays.asList(objs)); } }
