Discussion on JAVA

[CAILYN]

Hi,
Today JAVA is mostly used language. It is compatible platform to work on and develop applications. Java is a programming language for general use, and advanced object-oriented syntax, which is close to C. If I compare C with JAVA then I found the second one more easy and interesting. The the best thing is that the language works on many platforms. I need some suggestions regarding the same. Learning JAVA according to me is worth.

Java is interpreted. The source is compiled into pseudo code or byte code and executed by a Java interpreter: the Java Virtual Machine (JVM). This concept is the basis of the slogan of Sun Java WORA (Write Once, Run Anywhere: write once, run anywhere). Indeed, the byte code, it does not contain code specific to a particular platform can run and get almost the same results on any machine with a JVM. Java is interpretedJava is portable: it is independent of any platform. There is no specific compiler for each platform. The code remains independent of the machine on which it runs. It is possible to run Java programs on all environments that have a Java Virtual Machine. This independence is ensured at the source code with Unicode and byte code level.

Java is object oriented. As the most recent language, Java is object oriented. Each source file contains the definition of one or more classes that are used with each other to form an application. Java is completely object because it defines primitive types (integer, character, float, boolean ,...). Java is simple, his choice of authors has been to abandon elements misunderstood or exploited in other languages such as the concept of pointers (to avoid incidents directly manipulating the memory), multiple inheritance and operator overloading,. It is strongly typed all the variables are typed and there is no automatic conversion that could data loss. If such a conversion should be done, the developer must follow a cast or a static method provided as standard to achieve.

Java manages memory, allocating memory for an object is automatic and it automatically retrieves Java unused memory by the garbage collector that captures the areas of free memory left after the destruction of objects. Safety is an integral part of the delivery system and compiler. Planted a Java program does not threaten the operating system. It may not have direct access to memory. The hard disk access is regulated in an applet. Java multitasking, it allows the use of threads that are isolated execution units. The JVM itself, using multiple threads.

There are 2 types of programs with the standard version of Java applets and applications. A standalone application (stand alone program) is an application that runs under the direct control of the operating system. An applet is an application that is loaded by a browser which runs under the control of a plug in for it. The main differences between an applet and an application are: applets have no main () method: the main () method is called by the virtual machine to run an application. The applets cannot be tested with the interpreter, but must be integrated into an HTML page, itself viewed with a browser with a plugin-Smart Java applets, or tested with the applet viewer.
