Dynamic typing in Java

Question

Hi,
I keep reading that Java is predominantly a statically typed language, but with some added dynamic type checks at run-time.
What aspects of Java are dynamically typed?
Thanks

Try this little test, and then experiment some more.
class A {
  public void methA() {
    int i = 0;
    System.out.println("A.methA "+i);
class B  extends A {
  int i = 1;
  public void methA() {
    System.out.println("B.methA "+i);
public class AorB {
  public static void main(String[] args) {
    A a = new A();
    A ab = new B();
    B b = new B();
    a.methA();
    ab.methA();
    b.methA();
}
