   • Class Loader. When you compile a .java source file, it is converted into byte code as a .class file. When you try to use this class in your program, the class loader loads it into the main memory.
   • Runtime Data Area. There are five components inside the runtime data area: Let's look at each one individually. Method Area. All the class level data such as the run-time constant pool, field, and method data, and the code for methods and constructors, are stored here.
   • Execution Engine. Once the bytecode has been loaded into the main memory, and details are available in the runtime data area, the next step is to run the program.
   • Java Native Interface (JNI) At times, it is necessary to use native (non-Java) code (for example, C/C++). This can be in cases where we need to interact with hardware, or to overcome the memory management and performance constraints in Java.

   Aug 31, 2012 · The difference is that Java binaries compiled as x86 (32-bit) or x64 (64-bit) applications respectively. On a 64-bit Windows you can use either version, since x86 will run in WOW64 mode. On a 32-bit Windows you should use only x86 obviously.

   What is a Java Virtual Machine (JVM)?

   • A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation.

   What is Java Architecture?

   • The below-mentioned points and diagram will simply illustrate Java architecture: There is a compilation and interpretation process in Java. After the JAVA code is written, the JAVA compiler comes into the picture that converts this code into byte code that can be understood by the machine. And finally, the machine runs that machine code.

   What are the components of Java Architecture?

   • Java architecture consists of three main components and those are JRE (Java Runtime Environment), JDK (Java Development Kit), and JVM (Java Virtual Machine). Java programs can run in a runtime environment created by the JRE software. The Java Runtime Environment (JRE) is a disk-based system that mixes Java code with necessary libraries.

   What is a JVM language?

   • A JVM language is any language with functionality that can be expressed in terms of a valid class file which can be hosted by the Java Virtual Machine. A class file contains Java Virtual Machine instructions (Java byte code) and a symbol table, as well as other ancillary information.
