Java employs a virtual machine, which makes it platform-dependent. All APIs and the Java programming language are compiled into bytecodes. In actuality, bytecodes are platform-specific. The virtual machine handles the variations in bytecodes for various platforms. If you want to know Why is Java Platform Independent Language?

Java requires very little runtime. No code needs to be compiled for varied hardware because Java Virtual Machine takes care of all hardware-related difficulties.
Java has surpassed all other programming languages in popularity since its inception. The capacity to provide distinctive features is what has led to such a strong response. The grammar of Java is almost identical to that of C++, but it offers more functionality.
Java distinguished itself from all other programming languages of its era by supporting object-oriented programming (OOP). One of the reasons Java is the most popular language is that it was created with OOP at its foundation. This idea improves processing efficiency and reuse.
Many industries heavily rely on Java, including software development, web development, and application development. Additionally, it offers numerous libraries that make things simpler. Also, the availability of the IDE is a key factor in drawing developers’ attention.
Java can move different computer systems, effectively making it “run-once, anywhere.” Java’s portability is key to its superiority to the C language.
Compiling a Code
To make our code relatively legible, we always adhere to the grammar of a computer language. Additional words, phrases, variable names, method names, etc. are contained in it. All of this text is regarded as being readable and intelligible by humans.
Java is Platform Independent
When we type “javac filename.java” or compile Java code, javac performs the compilation. And it produces byte code, an intermediate kind of code.
Because Bytecode is platform independent, it gives Java this crucial functionality. This dependency makes Tasks easier since it requires less planning and translation to use in various scenarios.
Java distinguishes itself from all other programming languages in this area. With this, a.class file is produced, which is interpreted as byte code. Languages like C and C++, on the other hand, require a platform to compile and output natively executable code.
ClassLoader
It belongs to the Java Virtual Machine’s subsystem. It loads the.class file, looks for runtime exceptions, and raises a few of them. After checking, it allocates memory for variables and the prevailing techniques and gives arrays and variables default values.
In the code, static variables or methods are also implemented. The classloader handles the job, so the Java runtime does not need to be aware of the file or its settings. Classes are loaded as needed. FITA Academy offers the best Java Training with Live Projects. Placement guidance is provided for the applicants who complete Java Online Course.
JVM Language Stack
When a function occurs, it keeps the current information in blocks also referred to as stack-frames or frames, it maintains local variables, and it is heavily involved in thread management.
PC Register
It saves the address of the instruction that is presently running. This is helpful when there are multiple threads being executed.
