Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Some virtual machine emulators, such as QEMU and video game console emulators , are designed to also emulate or "virtually imitate" different system architectures thus allowing execution of software applications and operating systems written for another CPU or architecture. Operating-system-level virtualization allows the resources of a computer to be partitioned via the kernel. The terms are not universally interchangeable.

Jump to navigation. Java is commonly used to refer to the Java platform, a set of tools allowing for easy cross-platform application development, as well as the Java programming language, which is a general-purpose programming language often used to develop programs for this platform. The important thing about Java that differentiates it from many other technologies is that it is designed such that code written in Java can be run on any system that a Java virtual machine JVM can run on. Java environments can be found on all sorts of devices, large and small, and therefore a Java developer has more flexibility when it comes to being able to treat code as agnostic to the system on which it runs. Unlike some other languages which came before it, which implemented classes but did not require their use, Java programs are always designed with an object-oriented design. While the Java language and the Java virtual machine which runs Java code are closely paired, the two are separate. Code from other languages which is designed specifically for the JVM, like Groovy and Scala, can also run on the Java virtual machine.
Java (programming language)
Java is one of the most popular and widely used programming language. Java has been one of the most popular programming language for many years. Java is Object Oriented.
For every thread, JVM creates a separate stack at the time of thread creation. The memory for a Java Virtual Machine stack does not need to be contiguous. The Java virtual machine only performs two operations directly on Java Stacks: it pushes and pops frames. And stack for a particular thread may be termed as Run — Time Stack.
