What is the Java Virtual Machine and does it work?

What is a java virtual machine?

A Java Virtual Machine (JVM) is the software that interprets the compiled Java bytecode and runs the Java program. The Java Virtual Machine language conceptually represents the instruction set of a stack-oriented capability architecture. JAVA is a high-level object-oriented language, which is compiled using JAVA code.

It is first converted to highly efficient bytecode by the Java compiler and the generated bytecode is then interpreted by a JVM. Since Java is a platform-independent language, JVM is available for almost all platforms. It is for both windows and various portable devices.

Let’s get to know how the Java virtual machine works:

Java Virtual Machine does not have any information about programming languages. JVM only knows about binary bytecode format. The programmer can generate bytecode that adheres to this format in any of the programming languages. Every Java program runs within the limits defined by the Java virtual machine. Java code runs inside the JVM and cannot go beyond the security restrictions defined by the Java Virtual Machine. Java applications are considered safe applications on the Internet thanks to this software.

Java virtual machine language support:

Java Virtual Machine (JVM) was primarily intended for running compiled Java programs. Later on though, other languages ​​can now be run like Python with Jython, Common Lisp with Armed Bear Common Lisp, Ruby with JRuby, JavaScript with Rhino, Groovy, Scala and Forth with Misty Beach Forth. of the Java Platform.
