When I program I spend a lot of time using Google and reading through documentation. The fact of the matter is it's impractical for modern programmers to write code from basic principles. We have to...

You need to transfer the keyboard focus to the player's GUI. Unfortunately, I don't think this is something that can be done in pure Java.

Yep, more or less that's how a buffer works.

Yes, basically there's some fixed cost associated with performing an operation, plus some dynamic cost depending on the amount of data being requested...

The reason for Buffered streams (and buffers in general) is to mediate slow access operations, for example reading from a hard drive or across the network. The time it takes to read a byte from these...

Why not do something like this:


// java.net.URL imageUrl initialization here
URLConnection connection = imageURL.openConnection();
InputStream is = connection.getInputStream();
int size =...

Are you sure your code works? I can't get it to produce an actual output image.

It's not possible in pure Java. You'll need to use some native code to accomplish this. For example, Here's a post I made on how to accomplish this on Windows.

Alternatively, you can use the Java...

Matlab is very different from Java, but like jps said the problem at hand isn't necessarily language specific.

One program I've used in the past is WireShark, but generally I prefer to use the "standard" Java debug tools, i.e. Eclipse, Netbeans, whatever you use for debugging Java programs. I check the data...

What problems are you running into? I tested it and it works fine for me. Make sure you start the server before trying to run the client.

I've typically found testing using localhost is the...

If you're just doing some testing, use your localhost address: 127.0.0.1. This way you can safely create server/client connections on just your machine.

If you want to connect to another device,...

Don't post the same question multiple times on this forum, once is enough. Also, please use code tags.

Finally tags are always executed, regardless of if an exception was caught/thrown/propagated....

Look into how vectors (a.k.a. ArrayList) track "dynamic arrays". They don't always create a new array storage area every time the size of the list is modified.



This is a great application area...

JLS for SE5/6 (identical to each other)

I borrowed it from a friend, I'm not really sure where they got it from.

You can always print off pages if you don't want to stare at a monitor and put...

They are the easiest way, but there's nothing theoretically preventing someone from implementing their own versions of these classes (though I don't know why you would want to).

What is the...

Hey, I like my books! I just don't use them for Java or learning programming languages. They're great for science and engineering cause I tend to write in my books. A lot of good information is also...

I don't really have any good book recommendations, especially for Java. There are so many good online references that I just don't see the need to shell out a hundred dollars or so for a book that...

pi (π)

From the English alphabet, e.

What do you have so far, and what parts do you need help with specifically?

For getting user input, I would recommend using the Scanner class.

What errors are you getting (specifically)? If you're getting compile errors or runtime exceptions, please post the exact error message (text please, not screen-shots).

The best way to translate the code is to figure out fundamentally what the intent of the code is.

For example:


ulong num = 0uL;
for (int j = 0; j < 5; j++)
{
num <<= 8;
num |=...

You're code is checking to see if the player intersects every part of the ground instead of if it intersects anywhere on the ground (big difference).

A good method to do the latter:

1....

From a pure Java perspective, I would not do this even if it were possible. There might be some hack using reflection and code generation/compilation during runtime, but these solutions are all quite...

Sounds like a project in dire need of source control software (a.k.a. revision control software), and possibly some re-structuring.

You really shouldn't be tracking the version of a class in the...

A few important questions to ask (quite similar to each other, just slightly different):

1. What is the lifetime of GeneratorBase{n}? If you've gone to using GeneratorBase3, are you going to keep...
