Java robot class program

Robot is part of java. Robot class is basically used to generate native system input events for the purposes of self- running demos, test automation and other applications where control over mouse and keyboard is used.

Robot class generates events that can be used to control mouse, keyboard and can be used to take screenshots of the screen. In this article, we will implement Java Robot to move or drag the mouse to specified location. Methods used : mouseMove int x, int y : move the mouse to a specified location of screen keyPress int k : presses a given key with a specified keycode keyRelease int k : releases a given key with a specified keycode mousePress int b : presses one or more mouse buttons.

Program 1 : Java program to move a mouse from the initial location to a specified location Java. Label l, l1;. Interview Questions. Company Questions. Artificial Intelligence. Cloud Computing.

Note that depending on the platform configuration, multiple screens may either: share the same coordinate system to form a combined virtual screen use different coordinate systems to act as independent screens This constructor is meant for the latter case.

If screen devices are reconfigured such that the coordinate system is affected, the behavior of existing Robot objects is undefined. Parameters: screen - A screen GraphicsDevice indicating the coordinate system the Robot will operate in. IllegalArgumentException - if screen is not a screen GraphicsDevice. Parameters: x - X position y - Y position mousePress public void mousePress int buttons Presses one or more mouse buttons.

The mouse buttons should be released using the mouseRelease int method. Parameters: buttons - the Button mask; a combination of one or more mouse button masks.

It is allowed to use only a combination of valid values as a buttons parameter. A valid combination consists of InputEvent. The valid combination also depends on a Toolkit. If support for extended mouse buttons is enabled by Java then it is allowed to use the standard button masks and masks for existing extended mouse buttons, if the mouse has more then three buttons. In that way, it is allowed to use the button masks corresponding to the buttons in the range from 1 to MouseInfo. It is recommended to use the InputEvent.

The following standard button masks are also accepted: InputEvent.
