Jul 25, 2024 · The meaning of Java platform-independent is that the Java compiled code (byte code) can run on all operating systems. A program is written in a language that is human-readable. It may contain words, phrases, etc. which the machine does not understand. For the source code to be understood by the machine, it needs to be in a language understood ...
Sep 7, 2023 · Because of the platform-independent, Java gets an important feature called portability. Each system has its specific JVM that is installed automatically when the Java Development kit (JDK) is installed, and it is the JVM that reads the Byte code or .class file. Note: Now, we know that Java is platform-independent, but JVM is platform dependent.
JDK has a compiler that converts your Java code to bytecode and bytecode is platform-independent. JVM can read this bytecode and using an interpreter convert them to OS-specific instructions which vary based on your OS. All JDK, JRE, and JVM are platform-dependent. But JAVA is platform-independent because bytecode is platform-independent.

Method names, class names, and variable names are among the data it stores. It serves as a centralized resource for all the methods and variables in a class. It functions as a memory that holds necessary data to complete the task. It is shared across all the threads of the computer. The execution will determine if it is a fixed or expandable size.
The Heap keeps track of all the data that is kept in its area. It keeps the data in a specific amount that won't be known until the programme has been executed. It is utilized all through the programme. It is utilized for the allocation of dynamic memory. In the heap region, new items are developed.
When a function is executed, it keeps the current data in blocks, also known as frames or stack-frames maintain local variables and are heavily involved in thread management.
The address of the instruction that is currently being run is stored there. It is beneficial when there are multiple threads being executed.

Jun 18, 2013 · Java libraries (e.g. all the nice open-source toolsets) are usually platform-independent, as long as they are written in pure Java. Most libraries try to stick with pure Java in order to maintain platform independence, but there are some cases where this is not possible (e.g. if the library needs to interface directly with a special hardware or call a C/C++ library that uses native code).
May 1, 2010 · With Java, you can compile source code on Windows and the compiled code (bytecode to be precise) can be executed (interpreted) on any platform running a JVM. So yes you need a JVM but the JVM can run any compiled code, the compiled code is platform independent. In other words, you have both portability of source code and portability of compiled ...

Why does Java retain platform independence after code is compiled?
Java is a platform-independent language, meaning we run the same code on multiple platforms. Java code is both compiled and interpreted language. Java utilizes the JVM and Byte Code to enable platform-independent execution. The Java compiler converts programming code into byte code, allowing it to run seamlessly on different processors and systems.
