Why Java Is Platform Independent?

Java is one of the most popular programming languages in use today. It has been around for a long time and it is not going anywhere soon. In fact, Java continues to grow with more than 9 million developers worldwide. Java is platform independent which means that it can be used on any device or operating system without having to change anything about the code.

What does platform independent mean?

Platform independence is the ability to run Java code on any platform without modification. This allows programmers to create programs that are not limited by a specific operating system and can be deployed anywhere.

Why is Java Platform Independent?

Java is platform independent because it does not make any assumptions about the underlying hardware or operating system. This means that Java developers can write their code and run without worrying whether they are using Windows, Linux, Mac OS X, iOS, Android etc.

How is Java’s platform independence accomplished?

Java has a Virtual Machine that translates the Java code into instructions for the underlying hardware or operating system. The translated instructions are then executed by the software on top of it which makes the program work like it is being run in its original environment – even if there isn’t one!

Which platforms does java mainly support?

Java supports six platforms. These are:

Java SE – the standard platform for general purpose programming, running on billions of devices worldwide.

Java ME/MIDP – often used in mobile phones and other wireless devices to provide a rich user interface with limited memory resources.

Java EE – an integrated platform that delivers embedded applications as well as runtimes for web application servers and enterprise server systems.

Android OS – operating system designed by Google which is based on Linux kernel and uses the open source code from java (OpenJDK). It’s included in all new phone models released by Google since 2008.

JavaFX – a software platform for creating and delivering desktop applications, as well as rich internet applications (RIAs) that can run across multiple operating systems.

CrossOver Mac – an application available from the App Store which allows you to install Windows programs on your Macintosh computer. It is based on Sun’s open source codebase under the CDDL license and includes Wine libraries to support Microsoft Office 2013/2010.

How did it happen that java became crossplatform?

The exact date when JVM was first created isn’t known, but it was designed to be platform independent from the beginning. JVM is compiled into bytecode that can run on any type of computer with a Java Virtual Machine (JVM) installed regardless of CPU architecture or operating system

How does java access native functions?

Java provides an interface between the programming language and host environments by means of standard libraries and class libraries for various types of systems such as GUI-based programs or command line tools: The GCJ library compiles Java code to native machine instructions using gcc;

The GNU Classpath project adds new features while maintaining compatibility with existing ones in order to provide a free, extensible runtime environment where applications execute reliably without crashing either due to bugs in AWT/Swing components or due to conflicts with the native platform’s libraries.

What are some drawbacks about java?

Java has evolved over time but it still suffers from performance problems. The bytecode isn’t necessarily optimized for the current hardware and doesn’t always take advantage of CPU or GPU capabilities.

Some of the other drawbacks to java include:

– The language is verbose, which can make it difficult for newer programmers.

– Java’s execution speed isn’t as fast on some devices and operating systems compared with native code written in C or assembly languages. This causes either an app to be too slow or a device not powerful enough to run it at all.

Why would I want my program to be running in multiple environments?

In order for your application or game to succeed, you need it available on all platforms. By programming with Java as opposed to C++/Objective-C which has some limitations, developers have more options when downloading an app or playing a game through various devices. For example, if Apple does release their own version of Android phones at some point in time then using Java will ensure compatibility with both systems while still being able to take advantage of each device’s strengths. In addition, the Java programming language is less prone to security vulnerabilities and doesn’t need administrative privileges.


Having a platform independent language can help a programmer avoid having to learn many different programming languages.
