Hi,

    I am new to Java and coming from a C++ background ...... I have my
trusty Java books in hand. The similarity to C++ is obvious, but I m a
little confused about some of the logistics behind Java.

For example
when I declare an instance of an object in Java

class obj
{
    obj ()
    {
        // obj construct
    }
    // some methods
}

public static void main(String []arguments)
{
    obj x = new obj();
}
now is the new operator explicitly asking for memory ?..... and is x a
pointer of my type obj ?....
or does new have a total different meaning in Java ?

If so then what is the difference if I have
obj x;
 // or
obj y = new obj();

Thankyou if you can help.
