The instructor asked to create a jigsaw puzzle game on the web.
Problems found: After you click the randomly generated puzzle button, the disordered images cannot be restored.
Discovery process: each time a piece of puzzle is generated, it will test how it is spelled back. The result shows that sometimes it cannot be spelled back.
Mathematical Principle: If the parity of the inverse numbers of the two matric
In Android, threading, Process, JNI, IPC, and each small frame structure are basic skills. After learning the basics from the Android program ape to the architect's Road series with Gao teacher, I have some experience to record.Is Android development an app development? I've heard a lot of people say that Android learning is simple, making an app easy to get started with. I always feel that, many programmers do app development, the mind is roughly four components, a variety of layouts, databases

The APIs that apply these attachments are not packaged with the standard Java APIs that are used everyday, but are packaged in a special file called Tools.jar, which contains only a JDK-packaged release version of a virtual machine. Worse still, the location of this JAR file is not set, it is different in Windows, Linux, especially on the Macintosh VM,

APIs will also be modularized.JDK 9 will support many configurations, and scalability, security, and application performance will also be improved. Simplifying Java as a small device is the key to modular work. The Java Platform Module system, which is a component of the jigsaw project, will also be implemented.With modularity, developers are better able to build and maintain large applications for Java SE (Standard Edition) and EE (Enterprise Editio
