Closed 6 years ago.
I will be building a program on how to construct a NFA , the output of this particular program is visualise out the NFA in a graphical user interface. The final output of the program must be something like this:
My question is how do I get started on "drawing" the states in circle , adding edges , inserting the input between two states, how do I program the GUI part by using java? please help me out..
Ty to look to https://github.com/jgraph/mxgraph. There is swing/web examples. Manual is here https://jgraph.github.io/mxgraph/.

Given a tree how one could approach to draw the same using Java Swing that what we draw in a simple piece of paper to understand a tree ? i.e. drawing all the nodes an values inside the node circle as well as threads to join the parents with the child and so on .The Structure will be like this :
From https://en.wikipedia.org/wiki/Tree_%28data_structure%29#/media/File:Binary_tree.svg
You can use JavaFX for that:

That's the newest Java GUI technology!

How do I generate random integers within a specific range in Java?
(72 answers)
Closed 8 years ago.
i am wondering if you could help me in my project. I would to ask your opinion of what algorithm is best to used in generating random numbers that ranges from 1 to 9.. Its a game like "Sphere Break" a famous mini game of FFx-2.
Please refer to the picture for
Need Opinions Please!! Need Help Badly.
My problem is that i want a certain algorithm to generate random numbers from 1 - 9 like in the picture every gameplay = another set of random coins...
P.S. i am developing an android game using unity !! thx for the response
create a List<Integer> to hold 1-9 number and use Collections.shuffle() and render them

I am trying to match a prerecorded 3d(float x, float y, float z) linked list to another 3d linked list(float x, float y, float z). There is about 50 prerecorded sequences with 1000 examples of the same move every time, against which I am trying to match through.
The size of linked lists highly vary.
Is there a specific neural network pattern/library/framework/algorhytm in Java I could use for this task ?
Any suggestions would be highly appreciated!
Waiting for your replies)
If you insist on a neural network...
Simplify your prerecorded input
For each 3d point list create 3 black and white 2d images of your points (drawing a line between each adjacent point)
Top-down (x,z)
Forward-back (x,y)
Left-right (z,y)
Simplify your user input
Create the same 3 black and white images (explained above)
Find the bounding box of the points and scale the image to a uniform size
Having your user input, scaled to same size as your prerecorded input will facilitate recognition
Create neural networks for image recognition
Create a trained network for your prerecorded (3 images for each)
This seems like it would work http://neuroph.sourceforge.net/image_recognition.html
Build your neural nets from the black and white images (that represent the 2d mapping of your 3d points onto the 3 perpendicular planes)
Experiment with your matching bounds/constraints
IF Top2Bottom >= 0.75 AND Forward2Back >= 0.75 AND Left2Right >= 0.75
THEN IsAMatch = True
ELSE IsAMatch = False
I would probably just generate a large 3d corridor (think wide 3d tube, or a collection of connected cylinders) that represented the extremes of my prerecorded points then scale the user input points then check if the user input points fall within the matching corridor.
EDIT Very odd that the question itself was down-voted and closed, then days later my answer was down-voted. Realistically, the question was likely closed due to a failure of group think on the part of the moderators. Maybe it then looked a little awkward to have a closed question with a +1 "Accepted" answer, so this answer was subsequently down-voted (twice).
From my experience, the only way to ask a question like this is to either slap a large bounty on it, or re-word it in a way that won't offend the fragile sensibilities of the moderators (most of the time they do a good job and don't overstep...).
