thankls. Why is it better to use commandline and simple editor ?

I know that programming a microcontroller is a good way to understand how programming actually works.. for instance how different variables work the 1's and 0's behind the scene.
iTS a low level and I can appreciate learning simple stuff first.
Is that what you mean ? I find the eclipse no problem but I may be missing out on what is going on.?

I did think about Python, I have been programming a Parallax chip in SPIN which uses white space for program syntax control. kHeard Python is similar to Spin. However I like the idea of Java And I think it may have more in common with othuer languages than Python .

Is there a database that I can use with a Graphical GUI to create ?

I have seen a video of SQL server in VS Studio created in this way and was dead easy.

hi and thanks. could you point me toward good tutorials ?

I have already downloaded eclipse, is that going to be any good for the gui building ?
I havent really looked into it other than doing some beginner ''classes, getters and setters''.

Hello is there one IDE better than another for GUI ?

I need to learn a computer language to create a database and update via serial port.

Is there a database I can create with graphical tools ? Is there a serial port control in the GUI tools ?

Sorry for such basic question.

Thankyou all for the variety of answers. OIne of the reasons I have turned to learning Java is that despite my 'Windows World' comment .,I am building a PC to run Linux, so I can still program, ergo;Java

Also I found the comments interesting about sometime in the not far future most code will be written with languages that are platform independent.

Ive even heard VB and C# could be run on any platform if they can get the .NET framework installed. And yes I realise that C# is incredibly close to program like Java. I had a friend that new Java but not C# yet he was given the job of commenting on the C# and writing a kind of manual for others to follow the workings of the code!

thanks mIck. :twisted:

Well I just like doing stuff for hobbies. I started out with VB.Net, then wanted to build a moving flight sim platform and learnt enough C# to extract all the info i needed from MS Flight Sim 2004 and operate eletric motors from the serial port.
Now Im learning Java but to be really honest I dont know what java offers in a windows world. So for my benifit can I ask you all why you have decided to learn Java ?

Thanks, I had tried the equalsIgnoreCase(), it ran a little differently but i will have to rethink all the code as its just not happening the way I want. Thanks for putting me on the path!

Could anyone point out why the do while will not terminate when x is entered, it just continues to ask for
the stringgs to be entered without stopping as I thought it should when an x was enterd ?

import java.io.*; import javax.swing.*; public class FileOutputDemo { public static void main(String[] args)throws IOException { String firstString =""; String secondString = ""; boolean flag = true; do{ firstString = JOptionPane.showInputDialog("Enter a string"); secondString = JOptionPane.showInputDialog("Enter another String"); if (firstString == "x") flag = false; if(secondString == "x") flag = false; File outFile = new File("c:/averages.txt"); FileWriter aFileWriter = new FileWriter(outFile); PrintWriter aPrintWriter = new PrintWriter(aFileWriter); aPrintWriter.println(secondString + " " + firstString); aPrintWriter.close(); }while(flag != false); }//end main }//end class
[edit]Add code tags. CR[/edit]

The bok I like is by Richard A Johnson, Intro to java programming and object oriented Development. It can get a tiny bit tedious as it explains most lines of the code printed. Still for me itwas /is a great book.

I appologise for this half arsed question. , How come when you are working with file input/output you use the Throws IOException or similar to that.
LIke if you create a file that is already there I think that throws an exception. However there is no catch keyword with instruction what to do when an exception is throw. The program continues to run without you ever knowing an exception was throw ?

Sorry I have not posted the book title, I keep forgetting. One bgook that is very good especially as a quick reference is Core Java2 by Sun. That will be even handier when I am a bit further along the learning curve.

I will rember to post the full name of the first book, I have found the best by far next i am in town.

Can you drag and drop objects with Eclipse and NetBeans like you can in VIS Studio ? More interested in Eclipse.

Thanks Campbell, ill make do with that solution till i get better at hose IDE's

Thankyou very much for your response. I have been usinfg simple text editors for months and have had very few problems, cept when i scrw up the syntax, like it took me hours to find out why some code wasnt working , i had if(flag = true), that compiled fine of course because it was assigining. Of course programmers possibly yourself i have no doubt would have know the correct statment to be used was if(flag == true)

I have been trying netbeans and eclipse, not sure yet which i will prefer. I have been using quick fixes as you suggested.
I will post again later the title of the boo and author and publisher. I have 3 good java books but this one by Tthomson press is by far the best for begginer up to possibly intermediate programmer.

Can anyone helpm with this problem i am having with eclipse ?
