CNN for 1x8x8 Matrix outputs weird values?
I'm currently trying to create a CNN network with deeplearning4j which is supposed to evaluate chess games, it has a double[][] with one channel as Input and a single double value as output.
My training input data consists of double[][] onjects which are filled with the numbers -6.0 to 6.0 for the chess figures (-6.0 mean black king, 6.0 mean white king, 0.0 is an empty field) and the output data are centipawns, usually between -1000 and 1000 (negative numbers stand for an advantage for black, positive for white). Tho there are some centipawns beyond that like -20000 if someone has a really extreme advantage and even the maximum integer valua if there's a checkmate.
Now I try to train my CNN to calculate a centipawn for a Chess board, tho it only outputs positive insanly high numbers like 1.0E9...
Anybody knows how to fix that or what I could try?...

Am I supposed to making a Java class or interface file type?
I have to make a specific class but I am confused with the directions as this part doesn't give you the first steps on how to make it.
Scheduler class This is the user interface class to process the command lines entered on the terminal. An instance of this class can process a single command line or multiple command lines at a time, including the empty lines. You will lose 10 points if it cannot process multiple command lines. When your software starts running, it shall display "Scheduler is running.”. Next, it will continuously read and process the command lines until the “Q” command is entered. If the Q command is entered, display "Scheduler terminated", then the software stops normally. -2 points for each violation....

Weird issue that gets solved by wrapping it in a try/catch but it never gets caught
I'm coming from C# and learning Java and I stumbled across a bit of a weird issue with String.startsWith and String.equals in foreach loops.
I have a method to which I pass a String array, in this method I have a foreach loop that checks each string to a specific value using String.startsWith.
If I DON'T wrap the loop in a try/catch I get an error that says the current array item is null when it doesn't match,
but if I DO wrap it and put a breakpoint or println in the catch block, it's perfectly fine and I don't get any errors and the exception is never caught.

Jetty base resource help
Hey, I have a java app and I'm using jetty server
I used to have this code
context.setBaseResource( Resource.newResource( WebConfigurationProvider.class.getResource( "webapp" ) ) );
But after upgrading to jetty 12, Resource.newResource isn't available anymore
I replaced it with
```...How do I use the results of an action?
I'm trying to pass some information from user inputs back into my code but I don't really know how to go about it.
Basically, I'm making a Swing application that builds an XML file with a lot of repetitive lines and the idea is that the user will be able to input the unique values for each line, and the program will fill in the rest.
I have a dialog open with several text fields for the user to input information, once the user is done, I store the contents of these fields in a
List and then (after checking for bad input) use the List to create an object with the user data in the fields. I then need to add the toString of that object to the next line of my final output. ...Im trying to create an ArrayList of LinkedLists.
I want to create an ArrayList of n elements. N is a number the user inputs. Each element of the ArrayList will have a LinkedList of size n. Once the linked lists are created I'm suppose to input data. Can someone please guide me through the process? I have provided what I have coded so far, please take a look and if something is wrong, I'd appreciate the feedback.
Practice on an off day
Hi! I'm currently learning java through my college and I'm trying to figure out how i can practice all the things I've learned on my off day, as there aren't any ongoing projects for the class. If anyone has recommendations on what I can do to further practice the things I've learned and develop a deeper understanding of the different concepts, I'd love everyone's input!
