Hello,
I'm now reading Beginning Java 2 1.4
I've been trying to try out the illustrations in the book but it doesn't stay on the screen long enough me for to see.
I've keyed in the code for "delay ending program till you press Enter" on page 48 but it's still not working.
Point is I was initially using the SDK 1.4 software from the Sun website. I was not seeing my executed programs so I'm now using the JBuilder4 software from Borland.
Is there a way that I can freeze my program in order to see how I'm doing?
Any help from someone?

John,

If you are new to Java and programing in Windows, the best tools that you can use are a simple text editor and the Command prompt. Doing it this way means more work for you, but at least you start to understand what you are doing and don't become reliant on an IDE to build and compile your objects.

If you run your class from the Command prompt then you will find that you are able to easily view the output.

Cheers

Martyn

Hi Martyn,
Indeed I am new to programmimg. I took your advise and I'm now using JBuilder 4 Professional. I cam now compile programes successfully with it but anytime I want to run it it asks me to key in VM (virtual machine) and Application perameters which I don't know. Any help, please.

Johnmark,

If read my original email you will see that I actually advise againt using an IDE, which JBuilder is, partly for educational reasons and partly because you spend too much time trying to work out how to use the IDE rather than focus on coding in Java. Use JBuilder if you must but inititaly you would be better of with something like JCreator, which is free and is relatively simple to use.

I have version 9 of JBuilder, which could be very different from version 4, but I will try to help you.

You set the main class, vitual machine, and application parameters under: Project > Project Properties > Run


I hope this helps

Cheers

Martyn

No, you are not! If you WERE reading Ivor's book, you would have found a short example of how to delay the output on the MS-DOS screen so that it becomes readable. And it works! You just have to add a little piece of code to the end of the main() block:
(check the code example in chapter 1 or 2)

try
{
System.out.println("Press Enter to return");
System.in.read();
}
catch(IOException e)
{
return;
}
