Jan 22, 2010 · The JVM executes Java code, but is written in platform specific languages such as C/C++/ASM etc. The JVM is not written in Java and hence cannot be platform independent. answered Jan 22, 2010 at 21:29. Chris Kannon. 6,071 4 26 35. 2. Actually, several JVMs are written in Java: Maxine and Jikes are just two examples. – Jörg W Mittag.
Jul 25, 2024 · The meaning of Java 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 human-readable. It may contain words, phrases, etc. which the machine does not understand.
Jun 18, 2013 · In the specific case of Java: Java code is platform-independent in the sense that the same Java application or algorithms (typically compiled to Java bytecode and packaged in a .jar file) will run identically on Windows and Linux.

Java’shistory is as interesting as it is impactful. The journey of this powerful programming languagebegan in 1991 when James Gosling, Mike Sheridan, and Patrick Naughton, a team of engineers at Sun Microsystemsknown as the “Green Team,” set out to create a new language initially called “Oak.” Oakwas later renamed Java, inspired by Java coffee, and...
1. Platform Independent
Compilerconverts source code to byte code and then the JVM executes the bytecode generated by the compiler. This byte code can run on any platform be it Windows, Linux, or macOS which means if we compile a program on Windows, then we can run it onLinuxand vice versa. Each operating system has a differentJVM, but the output produced by all the OS is the same after the execution of the byte code. That is why we call java a platform-independent language.
2. Object-Oriented Programming
Javais an object-oriented language, promoting the use ofobjectsand classes. Organizing the program in the terms of a collection of objects is a way of object-oriented programming, each of which represents an instance of the class. Thefour main concepts of Object-Oriented programmingare: 1. Abstraction 2. Encapsulation 3. Inheritance 4. Polymorphism
3. Simplicity
Java’s syntaxis simple and easy to learn, especially for those familiar with Cor C++. It eliminates complex features like pointers and multiple inheritances, making it easier to write, debug, and maintain code.
Platform independent: Java code can run on any platform that has aJava Virtual Machine (JVM)installed, which means that applications can be written once and run on any device.Object-Oriented:Java is an object-oriented programming language, which means that it follows the principles of encapsulation, inheritance, and polymorphism.Security:Java has built-in security features that make it a secure platform for developing applications, such as automatic memory management and type checking.Large community:Java has a large and active community of developers, which means that there is a lot of support available for learning and using the language.Performance: Java can be slower compared to other programming languages, such as C++, due to its use of a virtual machine and automatic memory management.Memory management:Java’s automatic memory management can lead to slower performance and increased memory usage, which can be a drawback for some applications.Javais a powerful and versatile programming languagethat’s great for beginners and experienced developers alike. By learning the basics, like what classes, objects, and methodsare, you can start creating your own programs and see how Javacan be used in real-world applications. Whether you’re interested in building games, mobile apps, or websites, J...
