Java Archive file A Java Archive (JAR) file makes it possible to store multiple bytecode files in a single file. Java Bytecode – The instruction set of the Java virtual machine (JVM). Compiling Java source code results in a Java Bytecode that can be executed on any computer with an installed JVM.
We have designed this third edition of Java, Java, Java to be suitable for a typical Introduction to Computer Science (CS1) course or for a slightly more advanced Java as a Second Language course. This edition retains the “objects first” approach to programming and problem solving that was characteristic of the first two editions.
programmer only deals with the Java filesystem API. The virtual machine then handles translating between this “virtual” API to the true operating system API (see diagram B-2). What is Java? Part 3: Java Applets and Java Web Start Beyond the language, compiler, virtual machine and API, Java has a number of ancillary technolo-gies that .

Advantages of Using Java Once a Java program is compiled you can run the bytecode on any device with a Java Interpreter. –Because you do not have to recompile the program for each machine, Java is device independent. Java is safe. The Java

A Java program can run on several different CPUs and operating system combinations, usually with few or no modifications. Java programs are compiled with a Java compiler. The resulting format of a compiled Java program is platform-independent Java bytecode instead of CPU-specific machine code. Java Is Platform-Independent 8

The Java Virtual Machine: Java Virtual Machine (JVM) is the heart of entire Java program execution process. First of all, the .java program is converted into a .class file consisting of byte code instructions by the java compiler at the time of compilation. Remember, this java compiler is outside the JVM. This .class file is given to the JVM.
