      Introduction

      The world of programming is a very diverse one where each programming language has its own specific advantages. There are languages such as C and Assembly which focus on operating system instructions and other computer software while there are other languages such as HTML and JavaScript which focus on web-based applications. An example of a programming language that can do both is Java. This eBook contains guides and instructions that will help you learn and understand java in one day.

      So what is Java?

      Java is actually a decent programming language developed at Sun Microsystems. It was originally used for Internet applications or applets. Those applets are embedded on web pages and run in the browser. Java uses a special format known as byte code instead of an ordinary machine code. With the help of a Java interpreter program, the byte code can be executed on any computer. This Java interpreter program is called a Java Virtual Machine or JVM. It is available today in most computer systems. Java may use byte code format but there is nothing about Java that requires this byte code technique. There are some compilers that exist and generate real machine code, or more commonly known as native code.

      Java programs consist of sets of classes. The source files of those programs are written in .java. These source files are then compiled into .class files which contain the byte code instead of the CPU-specific machine code. The .class files are then executed by a Java Virtual Machine (JVM or interpreter) at run time.

      Java is not limited to Internet applications. It is technically a complete general object-oriented programming language which can be used to develop all sorts of applications. The syntax of Java is very much similar to the syntax of C++ but removes its error-prone features and complications.

      Do not mistake Java for JavaScript. JavaScript is an entirely different language.  JavaScript is an interpreted programming language used as one of the three essential components of a webpage or website content production.  The difference between Java and JavaScript is that Java is an object-oriented programming language while JavaScript is an object-oriented-scripting language. Codes written in Java need to be compiled while the codes written in JavaScript are all in text. Java creates applications that can run in both a virtual machine and a browser while JavaScript can only run on a browser.  Each language also requires different sets of plug-ins.

      Sun Microsystems, the company behind the creation of Java, offer free tools for developing Java-based software. If you want to know more
