Java is one of the most well-known and widely used programming languages. Because it uses a virtual machine, it is a platform-independent programming language. All APIs and the Java programming language are compiled into bytecodes. As a result, Java’s run-time requirements are extremely low. The Java virtual machine (JVM) handles all hardware issues. To learn more about Core Java, You can join Core Java Training In Chennai with Certification and Placement support for your career enhancement.
In this blog, we will learn about why Java is an independent language.
Why Java is an Independent Programming Language?
Java is widely used in various industries, including app development, web development, and construction software tools. It also comes with an extensive library, which makes things easier. The availability of an IDE is important in attracting developers’ attention. Integrated development environments (IDEs) such as Eclipse, IntelliJ, and NetBeans are popular among programmers.
Compiling Code
A compiler is used by a machine to convert source code into machine-readable code, also known as machine-level language. The compiler formats the machine-level code so that it can be easily understood by the CPU and it executes seamlessly.
JVM Architecture
The Virtual Machine (JVM) serves as a run-time engine for applications. The JVM is responsible for calling the main method in code. It is a machine abstraction. Enroll in the Best Core Java Training In Chennai at FITA Academy, which will help you to understand more about the programming language.
ClassLoader
- The Class Loader is a component of the Runtime Environment that loads classes dynamically into the Virtual Machine.
- In JVM, there are three built-in class loaders: bootstrap ClassLoader, extension ClassLoader, and application class loader.
JVM Language Stack
It stores data in blocks, also known as stack-frames/frames, which store current information when a function call is made, local variables are stored, and it also plays an important role in thread management.
Execution Engine
- The execution engine executes the byte code and releases memory allocated to inaccessible or unreferenced objects. The interpreter in the execution engine will run the byte code, reading it in a stream and understanding it line by line.
- It also includes an interesting feature known as the JIT compiler (Just In Time Compiler), which generates native executable code for methods so that the JVM does not have to interpret it twice if there are repeated function calls.
Interface for Native Methods
Java makes use of this interface to communicate with applications written in other languages, such as C/C++. Native methods access system-specific functions and APIs that does not provide. Because native methods involve system-specific code
