Robot Class in Java
This class is used to generate native system input events for the purposes of test automation, self-running demos, and other applications where control of the mouse and keyboard is needed. The primary purpose of Robot is to facilitate automated testing of Java platform implementations.
Using the class to generate input events differs from posting events to the AWT event queue or AWT components in that the events are generated in the platform’s native input queue. For example, Robot.mouseMove will actually move the mouse cursor instead of just generating mouse move events.

Example of Robot Class:
I have created simple example for Robot class using KeyBoard Events:
Just Follow this Step:
- Copy/Paste whole code in Notepad or any Editor.
- Save with named “JavaRobotExample.java“
- Run it
- You may ask for Editor name to run in your computer for e.g. notepad, wordpad, winword etc. whatever you can write in Run window.
- press Enter, now don’t touch keyboard or mouse and just wait for while Running… Typing… Saving…
