Playing an arbitrary tone with Android
(10 answers)
Closed 3 years ago.
So I'm trying to find out if its possible to create some sound waves that I can then manipulate using java, more specifically for the android platform. The Idea is to get integer values and using that, dynamically change pitch/pulse based on user input. I've looked into the soundpool class and it seems that that only handles sampled audio, I'm wondering if there is any way to actually generate it using code.
I'm assuming that if so, each wave generated would have to use it's own thread in order to manipulate them independently. Can someone confirm this?
Any help in the right direction is appreciated.
So I found this question whose highest voted answer is pretty much exactly what I was looking for. In any case, here's the link for reference:

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

How to determine the size of an object in Java

Yes , this question is little bit vague and any serious programmer would laugh about it ! Although java does not tell about the sizes it assigns to the varibles ,i mean it can give more memory or less memory depending on the situation( that way it is abstracted !)i know that stuff! but what i am asking is ,is there any technique that i can know about the runtime variable size ? i want to find the addresses of the variables too ! This question does not want any answers like ,see java docs it does not provide those functionality you have asked , i want some kind of hack to do this kind of stuff!
Well, There is no such direct way to get accurate size consumed by each object in JVM. Although you can you use JCONSOLE or other similar monitoring tool to get footprints of the objects dynamically. Again, this is more towards monitoring and performance tuning.
Thanks, Anil

Trie data structures - Java [closed]

I need to create a trie in Java for my Boggle game. I have tried searching for this site for help before hand but only got answers for C or Python but nothing on Java.
Anyways to keep it short, I was wondering how one would go about storing a dictionary (so like a text file of words; around 100k words) into a trie. I've read up about the trie and found it hard to visualize code for it.
Specifically I'm looking for steps to follow when programming (so like what methods I should include and what they do).
Any help would be appreciated!
Have you looked at TrieST? I really suggest you do. Otherwise, I suggest reading this article. Maybe also this one.

Hey guys is it possible to read text from an image, like how you go to submit a form and it ask you to fill in the text inside image. I want to know if it is possible to read the text inside it. If so, what language?

EDIT:
I am not trying to read captcha I was just giving an example of an image with text in it.
It is possible to read text with Optical Character Recognition.
However, CAPTCHAs are designed to thwart this, in order to distinguish humans from computers.

How do I normalize an image?
I am working on the implementation of active contours with gradient vector flow. I need to normalize the input image in the interval from 0 to 1 Unfortunately, I do not know how to do this in JAVA or JAI. If you can help me with some of your code or some link which can me help, many thanks.
If you want to use an already existing library, I can recommend ImageJ, which has a good set of image processing algorithms. You can find more in this SO question.
If you want to implement it yourself, that's quiet easy. Find maximum and minimum of your image in a run, then run over it again, rescaling every point.
