Java Trivia

-----------------------------------

Let's see how good the resident Java gurus really are.  :)

Two true or false tests.

In Java, all object types are passed by reference.

Java does not have pointers.

True. True. (although java references can contain null values and are re-assignable, it really depends on ur definition of a pointer/reference.. in my books a pointer is somthing to which u can directy assign a physical address as in C-pointers.)

False and false.  :)

public class Test
{
   public static void main(String

#include 
#include 

void foo(std::string& s)
{
   s = "Hello";
}

int main()
{
   std::string str("Foo");
   std::cout str = "Hello";
}  

int main()
{
   A *a = new A;
   std::cout str
