基于colt数学库，有完整源码，可以保存训练结果，基于开源例程neuralnetwork-sample的一个手写体数字识别软件

It's my honor to introduce the mini project "neural network sample" to you. If you try to use it, you must follow below steps: 0.Open this project via IDEA/EClipse 1.Write number(0~9) into the rectangle, then click "tell num" to tell software the number you have written. 2.Repeate step 1 five hundred times or more, then go to step 3 3.Click "train" button and wait training complete 4.Write number(0~9) into the rectangle, then click "test". The software will tell you the number it thought you write.
