What is java virtual machine?
Java is one of the leading programming languages today. A code widely used in different areas for the development of all types
of applications. To facilitate the execution of programs so that they can be tested, there is the Java virtual machine (JVM).
The Java virtual machine is a program that aims to execute other programs developed with Java. It is a simple idea but, as we will
see, it is especially useful in the field of programming with this language. Thus, the JVM altered the status quo of its time and,
today, continues to support innovation within Java programming.
So the Java virtual machine is a program that allows us to run other programs. It is, in essence, an execution environment that
can be added to both operating systems and any of the browsers we use. The JVM is capable of interpreting and executing instructions
expressed, obviously, in Java.
However, the peculiarity of the JVM is that it is a tool that makes Java, as a programming language, portable. That is, it is an
executable that makes this language interpretable on all types of systems and browsers. Thus, in all those that have a JVM,
applications and programs coded and developed with Java can be executed.
There is a motto that follows Java as a programming language that says: "write it once, run it anywhere." This is a reality
thanks to the JVM
The Java virtual machine can be implemented in all types of software, hardware or development tools. In this way, one of its
great uses for Java programmers is in the area of testing programs when they are still in the development phase.
Thus, the Java virtual machine has become one of the fundamental pieces of this entire platform. Sitting at a higher level than
the hardware of the system on which the application is executed, the JVM acts as a bridge that understands both the Java code and
that of the system on which it is executed.
