Just to give you a little excitement about Java programming, I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time. High Performance − With the use of Just-In-Time compilers, Java enables high performance.ĭistributed − Java is designed for the distributed environment of the internet.ĭynamic − Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. The development process is more rapid and analytical since the linking is an incremental and light-weight process.
COREJAVA BASICS CODE
Interpreted − Java byte code is translated on the fly to native machine instructions and is not stored anywhere. This design feature allows the developers to construct interactive applications that can run smoothly. Multithreaded − With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. Robust − Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.
COREJAVA BASICS PORTABLE
Portable − Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Authentication techniques are based on public-key encryption.Īrchitecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system. Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. If you understand the basic concept of OOP Java, it would be easy to master. Simple − Java is designed to be easy to learn. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on. Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. Java can be easily extended since it is based on the Object model. Object Oriented − In Java, everything is an Object. Java is guaranteed to be Write Once, Run Anywhere.
The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.
With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. The latest release of the Java Standard Edition is Java SE 8. Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 ).
