泛型数组 @SafeVarargs 怎么使用？-灵析社区
七厦import java.util.Arrays; public class Main { public static void main(String[] args) { String[] arr = asArray("one", "two", "three"); System.out.println(Arrays.toString(arr)); String[] firstTwo = pickTwo("one", "two", "three"); System.out.println(Arrays.toString(firstTwo)); } static K[] pickTwo(K k1, K k2, K k3) { return asArray(k1, k2); } @SafeVarargs static T[] asArray(T... objs) { return objs; } }  调`pickTwo`报错：` class [Ljava.lang.Object; cannot be cast to class [Ljava.lang.String; ` `@SafeVarargs` 怎么没效果呢？不是这样用的吗？
老詹啊老詹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));
}
}
