What is platform independent code in Java?

The meaning of platform-independent is that the java compiled code(byte code) can run on all operating systems. A program is written in a language that is a human-readable language. It may contain words, phrases, etc which the machine does not understand.

What is platform independent and example?

Platform independent means that the application can run in different operating system. Example:Applications written in Java can run in any operating environment. Ruby, Lisp, Scheme, Scala, Clojure, Python, Perl, PHP, C# (via Mono)... Honestly, the list could keep growing.

What is meant by platform independent?

Software that can run on a variety of hardware platforms or software architectures. Platform-independent software can be used in many different environments, requiring less planning and translation across an enterprise.

What is platform independence in programming?

Platform independence is a term that describes a technology (usually a ProgrammingLanguage or a FrameWork) that you can use to implement things on one machine and use them on another machine without (or with minimal) changes.

Is JDK platform independent?

JDK is platform dependent i.e for different platforms different JDK required. Like of JDK JRE is also platform dependent. JVM is platform independent. As JDK is responsible for prime development so it contains tools for developing, debugging and monitoring java application.

03 - Why Java is Platform Independent | All about Java Byte Code | JVM, JRE

What is mean by platform dependent and platform independent?

Platform dependent means software will functions only in one particular platform it won't work in all platforms means not in all operating systems. • Platform independence means implementing a code irrespective of the Operating System on which it is being implemented.

What is the difference between JDK and JRE?

JDK(Java Development Kit) is used to develop Java applications. JDK also contains numerous development tools like compilers, debuggers, etc. JRE(Java Runtime Environment) is the implementation of JVM(Java Virtual Machine) and it is specially designed to execute Java programs.

Why is platform independent important?

Platform independence is a desirable feature for software vendors because they invest a large amount of money developing a modern, sophisticated application so they don't want to artificially cut out any market segment. They want to sell their baby to as many organizations as possible.

Why Java is not fully platform independent?

Java's compiler converts the code written by the developer into bytecode. This bytecode is utilised by JVM (Java Virtual Machine) and converted into a language the machine on which Java is being run would understand. For this particular reason, that Java is platform-independent it is also portable.

What is platform dependent and platform independent in Java?

In Java, programs are compiled into byte code and that byte code is platform-independent. The byte code is executed by the Java Virtual Machine and the Java Virtual Machine is platform dependent. Java is platform-independent.

What is JRE and API in Java?

Components of Java Runtime Environment (JRE)

Java API (Application Programming Interface)

What is the difference between machine independent and platform independent?

A program that run at any OS means, that is called platform independent and those programs run at any architecture of computer (hardware) are called machine independent and the phenomenon is platform and machine independency.

Is JVM same as all platforms?

No, JVMs are not platform independent. In fact they are platform specific run time environment provided by the vendor. Each platform (Windows, UNIX, Mac etc) has its own JVM to run Java applications. Although the byte code supports connection to multiple databases..

What is Polymorphism in Java?

Polymorphism means "many forms", and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit attributes and methods from another class. Polymorphism uses those methods to perform different tasks.

What is encapsulation in Java?

Encapsulation in Java is a powerful mechanism for storing the data members and data methods of a class together. It is done in the form of a secure field accessible by only the members of the same class.

Why Java is called portable language?

Java is known as a "portable language" because Java code can execute on all major platforms. What's more, once you've compiled your Java source to "byte-code" .

What is robust in Java?

Robustness is the capacity of a computer system to handle the errors during execution and manage the incorrect input of data. Java is robust because it utilizes strong memory management. There is an absence of pointers that bypasses security dilemmas.

What is difference between JVM and JDK?

JDK is a software development kit whereas JRE is a software bundle that allows Java program to run, whereas JVM is an environment for executing bytecode. The full form of JDK is Java Development Kit, while the full form of JRE is Java Runtime Environment, while the full form of JVM is Java Virtual Machine.

Is Javac JRE or JDK?

Java Development Kit (JDK) is a software development environment used for developing Java applications and applets. It includes the Java Runtime Environment (JRE), an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc), and other tools needed in Java development.

Is JRE different from JVM?

JRE is an environment, in order to execute any Java program locally. JVM is where it's responsible for converting the Bytecode into machine specific code and makes java program write-once-run-anywhere.

Which of the following is considered as platform independent code?

What is this platform-independent code called? Answer 1: Bytecode.

What is open source in Java?

OpenJDK (Open Java Development Kit) is a free and open source implementation of Java SE. It is an alternative that allows more than 70% of Java developers to continue stabilizing their Java application environments while remaining within the open source ecosystem. OpenJDK is primarily licensed under the GNU GPLv2.

What is compiler and interpreter?

A compiler translates the entire source code in a single run. An interpreter translates the entire source code line by line. It consumes less time i.e., it is faster than an interpreter. It consumes much more time than the compiler i.e., it is slower than the compiler.

Is JVM a compiler?

JVM have both compiler and interpreter. Because the compiler compiles the code and generates bytecode. After that the interpreter converts bytecode to machine understandable code. Example: Write and compile a program and it runs on Windows.

Why JDK JRE JVM is platform dependent?

JVM, JRE and JDK are platform dependent because configuration of each OS differs. But, Java is platform independent. The Java Runtime Environment (JRE) is part of the Java Development Kit (JDK). It contains set of libraries and tools for developing java application.
