(Myth v/s Fact) Value or Reference

Java uses Pass-by-value (duh!!) what's so great about it ??,The fact is this innocous looking statement has been twisted, contorted to versions like " Java uses pass-by-value for primitive values and uses pass- by- reference for Objects."
The above statement is false since Java NEVER uses Pass -by -reference only pass -by -value. And when u pass an object to a method its the object reference that is passed by value and not the object itself.

What this means is that the following code will not work as expected
class DBConn {
// wrapper to connection object
}

class Appln{

// create and use DBConn to openConnection
DBConn dbObj = new DBConn(...);
// close the dbconn and make it avail for garbage collection
closeDBConn(dbObj);
// THE db OBJ is still visible here

public closeDBConn(dbObj)
{
dbObj=null;
}
}

THe above snippet of code uses closeDB(dbObj) where the dbobj is initialized to null this would
have worked if Java employs Pass-BY- reference but here it will not . for the simple reason that a duplicate/alias copy of the dbobj reference variable is made and this variable exists within the method scope .so initializing this reference to null will not make the object null
