JVM provides a translator, which converts byte code to native code or machine code.

#BEST JAVA TUTORIAL SOFTWARE#

JVM is a software that is developed using C and C++ languages, so JVM is platform-dependent software. It is software provided by Java to run Java programs or applications. What is the difference between byte code and machine code in Java?

Byte code is the collection of mnemonics (MOVE, LOAD, ADD ETC), these byte codes are only understood by JVM.

Byte code is a platform-independent code.

Byte code is an intermediate language (IL) code.

When the Java code is compiled java compiler (javac) generates byte code (intermediate code). Java programs compiled code is called byte code. The intermediate code can be carried and executed on any machine provided by a software called JVM which is responsible for converting intermediate code into machine code What is Byte Code? In this case, when the source code is compiled, the compiler generates intermediate code (byte code) rather than machine code, which is not specific to any OS. Java is a platform-independent programming language because the Java program compiled code can execute (run) on any OS. The programming language which is used for developing such types of applications is known as the platform-independent programming language. If the applications complied code is able to run on different types of OS irrespective of the OS where it is compiled then such applications are called platform-independent applications. Solution: Need to develop a platform Independent application.

C, C++ is called a platform-dependent programming language, because when C, C++ programs have complied, C, C++ compiler generates machine codes that are specific to the operating system.ĭrawbacks: We need to develop the same application multiple times which increases the development cost and time. The programming languages which are used to develop such types of applications are called platform-dependent programming languages. The programs or applications complied on one platform (operating system) can be executed on the same type of operating system but cannot be executed on other types of operating systems is called platform-independent applications. For example, a computer platform is( OS+ hardware devices) What is Platform Dependent? A platform is a hardware or software environment where a program runs. What is a platform?Ī platform is an environment where we execute something. JME is used for developing software for consumer electronics devices meaning embedded systems like mobile, it is popular for developing mobile gaming applications, fully automated washing machines, and robots. JME is used for developing device applications, such as mobile games and tablets. An application that resides in the server system and that is executed directly in the server system via network call and sends the response back to the client system is called a web application. There are two types of Internet applications, such asĪn application that resides in the server system and that is downloaded and executed on the client computer by network call is called a web-supportive application. JEE is used for developing internet applications. These applications are present in the server system. All internet applications are called distributed applications. What is an Enterprise Application?Īn application whose resources are shared among multiple clients is called distributed/ enterprise application. JSE is used for developing standalone applications. The application developed for the context of one client is called a standalone application. Device application What is a Standalone Application?Īn application installed in one system that can be executed from the same system but can’t be executed from another system is called a standalone application.

Enterprise / Distributed / Internet application.

These three different types of editions allow us to develop three different types of applications. Java comes in three different editions which allows us to develop three different types of applications. Java is a technology that provides two thingsīy using the language we can develop Java applications and also provides a runtime environment (JVM) where we execute Java programs. Java programming language is mainly designed to overcome the disadvantages of C and C++ and to develop internet applications by achieving platform independence. Each and every concept will explain with simple as well as real-time examples. In this Java Tutorials For Beginners and Professionals article series, we discussed all the basic, intermediate, and advanced concepts of Core Java with simple as well as real-time examples.
