What is the output of the following code?
class Gen<T> { T vals[];//w w w .j a va2 s. c om Gen() { vals = new T[10]; System.out.println(vals.length); } } public class Main { public static void main() { Gen<String> g = new Gen<>(); Gen<Integer> g2 = new Gen<>(); } }
Compile time error Cannot create a generic array of T
We cannot instantiate an array whose element type is a type parameter.
