introduction java the object oriented programming

Java is an object-oriented programming language with a built-in application programming interface (API) which can handle graphics, user interfaces and that can be used to create applications or applets. Because a lot of API's, similar to Macintosh and Windows, and its platform independence, Java can also be thought of as a platform in itself. Java also has standard libraries for doing mathematics.
Much of the syntax of Java is the same as C and C++. One major difference is that Java does not have pointers. However, the biggest difference is that you must write object oriented code in Java. Procedural pieces of code can only be embedded in objects. In the following we assume that the reader has some familiarity with a programming language. In particular, some familiarity with the syntax of C/C++ is useful.

to make java aplication we must create every think must be object oriented for the examples object oriented classes , object oriented database. in java many database can be embedded. embedded java database like mysql. In Java we distinguish between applications, which are programs that perform the same functions as those written in other programming languages, and applets, which are programs that can be embedded in a Web page and accessed over the Internet. Our initial focus will be on object oriented programming training. When a program is compiled, a byte code is produced that can be read and executed by any platform that can run Java.
To use this object oriented programming training you should run and study each program as you read along, so that you can see how added features affect the programs.
