How to create an instance of a class which is actually an array?

Question

the following code gives a runtime exception
Object obj = (Object )attributeClass.newInstance();
Exception:
java.lang.InstantiationException: [Ltest.Name;[/b]
Here test.Name is user defined class and i want to create an array instance of that class.
I have tried the following also:
[b]Object methodArgs[] = new Object[length];
for(int j=0;j<length;++j){
methodArgs[j] = singleMemberClass.cast(testArray[j]);
Object temp = attributeClass.cast(methodArgs);
In the above code singleMemberClass is test.Name, but the last line gives the following exception.
java.lang.ClassCastException

Try the following code
import java.lang.reflect.Array;
public class TestReflection {
     public static void main(String args[]) {
          Object array = Array.newInstance(A.class, 3);
          printType(array);
     private static void printType(Object object) {
          Class type = object.getClass();
          if (type.isArray()) {
               System.out.println("Array of: " + elementType);
          System.out.println("Array size: " + Array.getLength(object));
class A{
}
