How To Get the JDK

• http://java.sun.com/javase/downloads/– See instruction document on course website

Where Do We Write Our Java?

• We will be using TextPad– www.textpad.com– Follow instruction document on course website

• There are a number of other options– even just notepad

• But then we have to access the JDK commands directly– open a command line window (start -> run, then type “cmd”)– Navigate to our saved java file– To compile: “javac <insert filename>.java– To run compiled program: “java <insert filename>

First Program (Don’t Sweat the Details)

class HelloWorld{

public static void main(String[] args){System.out.println("Hello all");

}}

To-Do for This Week:• Look through chapter 1

• Download and install the JDK

• Download and install TextPad

• First Application– Enter the “hello world” text into a textpad window– Click “save as”– Change the filetype to “any”– Save as HelloWorld.java– Compile your java file (tools -> external tools -> compile java

application)– Run your application (tools -> external tools -> run java application)
