JVM (Java Virtual Machine) JVM is a virtual machine which work on top of your operating system to provide a recommended environment for your compiled Java code. JVM only works with bytecode. Hence you need to compile your Java application(.java) so that it can be converted to bytecode format (also known as the .class file). Which then will be used by JVM to run application. JVM only provide the environment It needs the Java code library to run applications. JRE (Java Run time Environment) JRE contains everything required to   run   Java application which has already been compiled. It doesn’t contain the code library required to develop Java application. JDK (Java Development Kit) JDK contains everything that will be required to develop and run Java application.

 05, 2017 History of Java James Gosling initiated Java language project in June 1991 for use in one of his many set-top box projects. The language, initially called ‘Oak’ after an oak tree that stood outside Gosling's office, also went   by the name ‘Green’ and ended up later being renamed as Java, from a list of random words. Sun released the first public implementation as Java 1.0 in 1995. It promised   Write Once, Run Anywhere   (WORA), providing no-cost run-times on popular platforms. On 13 November, 2006, Sun released much of Java as free and open source software under the terms of the GNU General Public License (GPL). On 8 May, 2007, Sun finished the process, making all of Java's core code free and open-source, aside from a small portion of code to which Sun did not hold the copyright. Popular Java Editors To write your Java programs, you will need a text editor. There are even more sophisticated IDEs available in the market. But for now

Java Tutorial About JAVA TECH KNOWLEDGE MASTER, Java Tutorial Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. Java programming language was originally developed by Sun Micro systems which was initiated by James Gosling and released in 1995 as core component of Sun Micro systems' Java platform (Java 1.0 [J2SE]). The latest release of the Java Standard Edition is Java SE 8. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications. The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively.  Java is − ◆ bject Oriented  − In Java, everything is an Object. Java can be easily extended since it is based
