Just because software is written in a popular programming language such as C or C++, it does not mean it will run on all OSs that support that language-or even on different versions of the same OS. One example is, which in 2006 did not natively run on AMD64 or Intel 64 processors implementing the x86-64 standards by 2012 it was "mostly" ported to these systems. Software written for one OS may not automatically work on all architectures that OS supports. For example, Linux uses a different API from Windows. Developing such software can be a time-consuming task because different OSs have different application programming interfaces (API). There are also subsets of Java, such as Java Card or Java Platform, Micro Edition, designed for resource-constrained devices.įor software to be considered cross-platform, it must function on more than one computer architecture or OS.

For mobile applications, browser plugins are used for Windows and Mac based devices, and Android has built-in support for Java. The Java Native Interface (JNI) can also be used to access OS-specific functions, with a loss of portability.Ĭurrently, Java Standard Edition software can run on Microsoft Windows, macOS, several Unix-like OSs, and several real-time operating systems for embedded devices. For example, disk and network access is usually enabled for desktop applications, but not for browser-based applets. This lets users to decide the appropriate protection level, depending on an ACL.
The JVM makes the system calls on behalf of the Java application.

Java code running in the JVM has access to OS-related services, like disk I/O and network access, if the appropriate privileges are granted. Java software can be executed by a hardware-based Java processor. This enables the same code to run on all systems that implement a JVM. The Java VM ( JVM) is a CPU implemented in software, which runs all Java code. The Java language is typically compiled to run on a VM that is part of the Java platform.

Hardware Ī hardware platform can refer to an instruction set architecture. For example, the Java platform is a common VM platform which runs on many OSs and hardware types. Applications can be written to depend on the features of a particular platform-either the hardware, OS, or virtual machine (VM) it runs on. There are, however, many devices such as smartphones that are also platforms. Other well-known desktop platforms are Linux/ Unix and macOS - both of which are themselves cross-platform. An example of a common platform is the Microsoft Windows OS running on the x86 architecture. Platform can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, the type of OS, or a combination of the two.
