Architecture Dependent /* My first C program. b) Verifies all bytes code of .class file proper or not . c) Memory is divided into 5 areas Java was designed to support applications on networks. The JVM performs following operation: According to Sun, Java language is a simple programming language because: 1. That is the architectural neutral part. Java is written to be write once,run anywhere.Java is architecture neutral only because the JVM abstracts away the specifics of the particular machine where java code runs on.Java has different implementations of the JVM (called JRE) for different OS. Thus when you write a piece of Java code in a particular platform and generated an executable code .class file. Why in Java there is no multilevel inheritance? It's the specification of an abstract machine for which Java programming language compilers can generate code. To enable a Java application to execute anywhere on the network, the compiler generates an architecture-neutral object file format--the compiled code is executable on many processors, given the presence of the Java runtime system It can also compile it into native code with a JIT (a just-in-time compiler that compiles and caches your code, usually one method at a time). Java application runs the same bytecodes regardless of any environment (Operating System). 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. Java is true object-oriented language. Since Java supports this feature it can be created and stored on the basic platform following the prompts.

If you are developing and selling a software product, Java's support for platform independence can help you to compete in more markets. More so than Java. Whereas C and C++ are complied languages which makes them platform dependent. … Architecture Neutral. What is JVM As part of step 1 you convert the code as part of compilation to "binary code format" that's independent of hardware architectures, operating system interfaces, and window systems. When we will run the byte code, it is converted into native code with the help of JVM and then it will be executed. JVM makes this possible because it is aware of the specific instruction lengths and other particularities of the platform. When you issue a command like java , the JVM loads the class definition for that particular class and calls the main method of that class. Credit for JVM: http://net-informations.com/java/intro/jvm.htm. Java language and Java Virtual Machine helped in achieving the goal of “write once; run anywhere, any time, forever.” Software that is designed without regard to the target platform. Although many object-oriented languages began strictly as procedural languages, Java was designed from the … Thus when you write a piece of Java code in a particular platform and generated an executable code .class file. The interpreted nature of Java technology solves both the binary distribution problem and the version problem; the same Java programming language byte codes will run on any platform. Java's platform independence consists mostly of its Java Virtual Machine (JVM) . - Executes code. Networks connect platforms with different architectures based on various microprocessors and operating systems. With the java runtime system presence, its covert compiled code to executable form. Almost “Everything is an Object” paradigm. # Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. This make java architectural neutral.While both are not present in every language, Compilation is done outside JVM (Java Virtual machine).Compilation means conversion of .java file into .class file. That is the architectural neutral part. When you run a Java program, it runs as a thread within the JVM process. Dynamic and Extensible.
