JAVA程序训练实验。建立10*10的随机灰度值图像，利用均值滤波算法进行滤波，并在控制台中输出。-Create a random image of 10*10 pixels and print it out. Then filter the image by using average filter algorithm which makes a new image of 8*8 pixels because the brim elements cannot be filtered due to the absence of enough elements, and then print it out.
