Dear newsgroup

With the following code, what is the difference from one written with 
Bounded Type Parameters? the code has type 'Number' with the 'add' 
method using the 'Integer' type. How can I stop a subtype from being 
passed to the 'add' method?

public class Test<T> {
  private T t;
  public void add(T t) {
  this.t = t;
  }
  public T get() {
  return t;
  }
  public static void main(String[] args) {
  Test<Number> test = new Test<Number>();
  test.add(new Integer(10));
  System.out.println(test.get());
  }
}


thanks in advance

Neil
