JDK, JVM and JRE in Java
Java is a powerful, versatile programming language used to build a wide range of applications, from mobile apps to large-scale enterprise systems. A key part of working with Java effectively is understanding its core components: the JDK (Java Development Kit), the JVM (Java Virtual Machine), and the JRE (Java Runtime Environment). Java Virtual Machine(JVM):- The JVM is a virtual machine that enables a computer to run Java programs. It converts Java bytecode, produced by the Java compiler, into machine code that the host operating system can execute. The JVM's ability to run bytecode on any platform that has a compatible JVM implementation makes Java a "write once, run anywhere" language. JVM Architecture:- Class Loader Role : The class loader is responsible for dynamically loading Java classes into the JVM. It loads classes from the filesystem, network, or other sources as needed. Types : Bootstrap Class Loader : Loads core Java libraries located in the <JAVA_HOME...
