Introduction

Welcome to Java All-In-One Desk

Reference For Dummies, Second

Edition-the one Java book that's designed to

replace an entire shelf full of the dull andtedious Java books you'd otherwise have

to buy This book contains all the basic(and not-so-basic) information you need toknow to get going with Java programming-starting with writing statements and usingvariables, and ending with techniques forwriting programs that use animation andplay games Along the way, you find

information about programming user
