The objective of this book is to teach both how to use and to develop with the Java Language The reader is continued on page 5 Opening Windows continued from page 1 have established a TCP IP connection Try using ping with a name rather than a number The same hosts can be pinged with PING www imicrosoft com PING www ibm com PING www nrcan gc ca If you do not get a response now the problem is that you do not have access to a Domain Name Server DNS which is what translates friendly names like wwwnrcan gc ca into the numeric address required to actually access a machine on the Internet Review the instructions that your ISP gave you Most likely you entered in the wrong address for the DNS server It is also possible that all DNS servers you have access to are down right now If you get a response at this point you know your basic TCP IP is functional and you have access to a working DNS server If you are still having problems they are most likely related to your web browser itself It may require a re install You may want to talk to the tech support people at your ISP Tell them the steps you have taken above and ask them how you should proceed TCP IP tools In addition to Ping which was used above Windows 95 provides a number of TCP IP tools that can help you in your computing on the Internet While many think of the Internet as just the World Wide Web it is so much more and Windows 95 provides some rudimentary tools

Java by example continued from page 3 brought up from the very basics of the language its constructs and features what is object oriented programming how to implement OOP in development creating applets and putting all the pieces together A well thought out feature is in the selection of examples in general the examples are interesting and educational One instance is the example of the four function calculator We have all at sometime or another used a variation of the four function calculator to do some needed calculation Some of us may have even wondered how it works internally The book explains the code necessary to develop the four function calculator code Another example we have probably encountered is the puzzle where the objective of the game is to slide the pieces around until a certain pattern is arrived at On a more practical example the code and May Ottawa PC User s methods are shown for creating a form for data entry One topic this book does not cover is the developing of code for Websites but anyone working through the book and learning to code in the Java language has the tools for developing Java applications for Web sites Again Java by Example is a very well written book on the Java language It is highly readable and should be considerd one of the books use to learn Java programming Java by Example by Jerry R Jackson and Alan L McClellan for intermediate and advanced programmers Comes with CD ROM Pub
