Introduction to the JDK Java for Computational Finance

JDK Our choice of development environment –A product of Sun Microsystems (the creators of Java) –Most popular environment and most up to date –Widely available (free from –Widely tested –Simple to Use

JDK Simplicity has its price –Functional environment, but not many bells and whistles –Command line interface –Less than adequate debugging tools

JDK What you get with the JDK? –Java Virtual Machine Implementation –Java Core API –Documentation –Development Tools

JDK Virtual Machine Implementation –Abstract computing machine and execution environment for Java byte-code –Java bytecode runs on the virtual machine, and thus runs on any platform with an implementation of the VM –The code is independent of the platform underlying the VM!

JDK Java Core API –Essentially the raw materials from which you will build programs –Collections of classes organized in packages java.lang(Object, Integer, String ….) java.util (Vector, Hashtable, Date….) java.awt (Window, Menu, Button….) java.net(Socket, URL, DatagramPacket….) and more ….

JDK Documentation –HTML documentation on the Core API –Organized by Package –Documents fields and methods of each class –Was created automatically via javadoc (as we’ll see later)

JDK Tools –A wide array of tools for aiding development –Most importantly: javac java javadoc

JDK Tools –javac The Java Language Compiler that you use to compile programs written in the Java Programming language into platform-independent bytecode javac MyProgram.java

JDK Tools –java The Java Interpreter that you use to run programs written in the Java Programming Language. java MyProgram

JDK Tools –javadoc Generates API documentation in HTML format from Java source code. Requires some work on your part (a commenting format must be followed) javadoc MyProgram.java
