  1. What Is Java For Intermediate Java, was developed by Sun Microsystems, by James Gosling, is an object oriented programming language.

  2. Introduction to Java • Java, was developed by Sun Microsystems, by James Gosling, is an object oriented programming language. • Now oracle has taken over sun Microsystems, so all the products of sun comes under Oracle license. • Now Java has become more than a language as time passed. It is a platform because it has its own Runtime environment, has open source API, distributed programming through RMI. • It may look like very unclear but you will feel better after started learning Java.

  3. Language of Java • First and foremost Java is an object oriented programming language. Object oriented means we have to develop software collection of distinct objects. There is a famous saying about Java: WORA (Write Once Run Anywhere). • Java are saved in any editor (e.g.: notepad, notepad++) with java extension. These source codes are then compiled using Java compiler which converts it into Java byte code , and then byte code is executed using the Java Virtual Machine (JVM). Both java compiler and Java Virtual Machine are the part of java development kit.

  4. Java Bytecode • Java Byte Code is a code which is stored in a separate .class file which is created after compiling your source code. • We can run this byte code on different-different operating systems by using their specific JRE. • In other words we can say Java is platform dependent in case of JRE.

  5. Java SDK And JRE Java Software Development Kit (Java SDK) The Java SDK (Software Development Kit) is the complete package to develop any java software. It has many tools in bin folders; like Javac, Javap, javadoc, java etc.It is the combination of JRE and other library tools. Java Runtime Environment (JRE) For executing any compiled class, Java Runtime Environment provides a runtime environment for it. It is the combination of JVM (Java Virtual Machine) plus other libraries. It reads the code line by line and executex the code.

  6. Java Code Conventions And Applets Java Code Conventions As per the oracle standard, to write code as per the naming convention is a good programming practice. Naming conventions are given for class, package, function, variable etc are to be followed. Java Applets Java Applet is a program which executes and runs on web browser. To run an applet browser must have enable Java plugin.
