Java Applications are found everywhere- on mobile phones, Blu-ray disc players, set top boxes, and even in your car(SUV or MUV). Today Java is so famous for its tools and services it gives while developing applications that is found everywhere. Even operating systems have been developed with the help of java, For example- Apple computers 'MAC', Fedora-2, etc. The Global Positioning System(GPS)/Navigation Systems are developed under Java, The 'Packets' in GPRS can be developed using Java socket programming, i will teach you in further Conversations.
Java is Completely Object Oriented ie object depends on its Data and not on the Codes. Other Languages Like C are process oriented ie object depends on its Code and not on Data.
For Execution or Running java, java uses 'Java Virtual Machine'.JVM understands(READ)/interprets ByteCode. ByteCode is a set of instructions which are designed to be executed by the java runtime system ie JVM. ByteCodes are Binary codes and Machines can understand only 0's and 1's ie Binary Code. Therefore java can reach up to machines which other application developing languages can't do.
Java is:
1) Simple
2) Object Oriented
3) Robust
4) Multithreaded
5) Architecture Neutral
6) Interpreted (can be run\access\loaded to any machine, it is not depended on the particular machine, this feature is used in web applications)
7) Distributed (java makes easy in Client/Server communication with this feature,
here client is the person wants a particular information and server possess this information)
8) Dynamic (this feature helps to dynamically link code in a safe manner)
Java language is a set of code containing in the libraries(contains set of universal code used while coding in java) executed by classes(such codes are classified under classes) and stored inside itself for future execution.
Java Consists of two parts the 'Core version' and the 'Advance version'.
In the Core Version of Java, I will teach you with the basics of the programming.
