The Java programming language requires the Java virtual machine (JVM) to function properly. The JVM interprets requests and converts them into machine language. The JVM is platform independent, making Java programs versatile and able to run on multiple operating systems. The JVM also supports multitasking capabilities, saving processing resources and making applications run faster.
The Java® programming language uses special management software called the Java® virtual machine (JVM). This JVM is required for any Java® software program to function properly on a computer. The JVM interprets requests from a software program and converts them into machine language that the computer hardware understands. The JVM is hardware platform independent, making it suitable for many types of computer operating systems.
Most programming languages today are hardware platform specific. These programs are known as proprietary because they can only run on specific operating systems. The Java® virtual machine is the special element that makes Java® programs platform independent. This JVM is an automated linking process that manages communication between computer hardware and Java® programming code.
When a computer user turns on their computer, they interact with the computer hardware and software operating system (OS). Your computer’s operating system is the primary device that captures actions from your computer’s mouse and keyboard. These events are transmitted from the operating system to the program using special operating system code. The Java® virtual machine is a Java® process that captures operating system events and transforms them into understandable Java® messages.
Using a Java® virtual machine offers many benefits. The technical nuances of each operating system are hidden from the developer. This allows for greater versatility for the program because it can work with multiple computer hardware platforms. The JVM also allows for the flexibility to use more than one operating system platform within your organization.
Today, several operating systems are available, including Windows®, MAC®, UNIX® and Linux®. A single Java® software program can run on multiple versions of operating systems. This is because Java® programs use the JVM to interact with the operating system. Other types of software code typically require a separate build codebase for each operating system.
Microsoft®.NET is an example of a software language that requires specific compilation for each operating system. To distribute this type of software in a UNIX® environment, the code would need to be recompiled. This would require maintaining multiple code bases for each operating system used.
Today Java® virtual machine technology has been deployed on millions of computers and devices around the world. This JVM is freely available on the Internet with the Java® development software environment. This process is installed automatically when Java® software code is installed on a computer.
Multitasking is a process that allows multiple programs to run in parallel on a computer. The Java® virtual machine supports multitasking capabilities. This technique allows a JVM to support multiple concurrent applications. The availability of multiprocessing capabilities saves valuable computer processing resources, which makes applications run faster.
