magicCube.jar为可执行文件，需要在java环境下运行，需要计算机配置好jre；在输入页面输入一个正整数，当这个正整数不大于30时，会弹出页面显示幻方；当输入数据大于30时，数字在页面上显示会非常拥挤，不便于查看，所以程序将求出的幻方存储到d:/magicCube.txt文件中，请到该目录下查询。-magicCube.jar for the executable file, you need to run the java environment, you need a computer configured jre　in the input page, enter a positive integer, when the positive integers not greater than 30, it will pop up page display magic squares　when large input data 30, the number displayed on the page will be very crowded, not easy to see, so the program will find the magic square store to d:/magicCube.txt file, go to the directory query.
