Java bytecode

Java bytecode (.class) can be executed using a virtual machine. The software program that runs this virtual machine is called the Java Virtual Machine (JVM). The JVM interprets the bytecode, which is created by compiling the Java source code, and translates it into machine code that can be understood by the computer's processor.

The JVM was developed by Sun Microsystems (now Oracle Corporation) and is available for different operating systems such as Windows, Linux, and macOS. It provides an environment in which Java applications can run independently of the hardware and operating system.

One of the advantages of using the JVM is that it ensures the portability of Java code across different platforms. As long as the JVM is installed, the same bytecode can run on any computer, regardless of the hardware architecture or operating system.

Another benefit of the JVM is that it provides memory management and garbage collection, which helps improve the performance and reliability of Java applications.

However, there are also some limitations to using the JVM. For example, it can be slower than native code, which may affect the performance of high-performance applications. Additionally, the JVM may not support certain native system calls or libraries that are required by some applications.

Despite these limitations, the JVM remains an important component of the Java ecosystem and is widely used by developers to create cross-platform applications.
