Java: Write Once, Run Anywhere (WORA) - A Deep Dive into Platform Independence

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.

Top 5 Java Features: Examples and Explanations

The five major features of Java are polymorphism, Lambda expressions, StreamsAPI, generics and exception handling. 1. Polymorphism allows objects of different classes to be used as objects of common base classes. 2. Lambda expressions make the code more concise, especially suitable for handling collections and streams. 3.StreamsAPI efficiently processes large data sets and supports declarative operations. 4. Generics provide type safety and reusability, and type errors are caught during compilation. 5. Exception handling helps handle errors elegantly and write reliable software.

JVM Internals: Diving Deep into the Java Virtual Machine

The core components of the JVM include ClassLoader, RuntimeDataArea and ExecutionEngine. 1) ClassLoader is responsible for loading, linking and initializing classes and interfaces. 2) RuntimeDataArea contains MethodArea, Heap, Stack, PCRegister and NativeMethodStacks. 3) ExecutionEngine is composed of Interpreter, JITCompiler and GarbageCollector, responsible for the execution and optimization of bytecode.
