Java about the use of robot classes and the implementation of remote desktops

Using the robot class to achieve automatic operation, the effect is to run the mouse automatically positioned to the entire screen coordinate system (635,454) position, input Wangtianze

Using the robot class to implement the monitoring screen, the effect is to run every 50 microseconds to get the current screen image, displayed in the JFrame

The above two is the use of robot class demo, since I have used the robot class to achieve automatic operation, as well as screen monitoring, then in-depth, if you join WebSocket to achieve instant communication, then you can realize remote monitoring and control the function of the desktop.
