It is always a good practice to know a little bit of history and background of any technology before starting to actually use it. In fact Java has nothing to do with the 'Island Java' in Indonesia. It all started at Sun Microsystems when they were developing an application for the 'set-top box'.

There are a number of C++ features that Java does not support. In some cases, a specific C++ feature simply didn't relate to the Java environment. In other cases, the designers of Java eliminated some of the duplication of features that exists in C++. In still other instances, a feature of C++ is not supported by Java because it was deemed too dangerous for Internet applets.

Java has changed tremendously and included more features over the years. The first basic version of Java comprised of just six packages. A package is a collection of Java classes.

For the most part, it is quite easy to convert a C++ function that uses pointer parameters into its equivalent Java method. Since Java passes all objects by reference, sometimes the conversion simply requires the removal of C++'s pointer operators. For example, consider this C++ program that reverses the signs of a Coord object, which stores a pair of Cartesian coordinates. The function reverseSign( ) is passed a pointer to the Coord object that will be reversed. As you can see, C++'s *, &, and -> pointer operators are used to perform the operation.
