Rejected The operation experienced an error.Ī promise always starts out in the pending state.

Fulfilled The operation completed successfully.

Recall that a promise is a state machine with 3 states:

onRejected(): JavaScript will call this function if the underlying async operation failed.onFulfilled(): JavaScript will call this function if the underlying async operation succeeded.The then() function takes 2 callback function parameters: Create a promise that is immediately fulfilled with value 42. That JavaScript will call when the value is computed. To get a promise's value from the promise directly - you need to call the You can think of a promise asĪ placeholder for a value that hasn't been computed yet.

Note that this is done through the repaint method, which calls the update and then paints method, due to which we are able to see visible shapes immediately after click event is performed.Representation of an asynchronous computation. JFrame frame = new JFrame() // creating a jFrame objectįrame.getContentPane().add(new RepaintDemo()) // Adding WindowįtTitle('Repaint Method Demo') // set title of the windowįtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) įtSize(375, 250) // set size of windowįtVisible(true) // set window as visibleĪfter the mouse click event is performed, the following shapes will be visible with a black color border. Public class RepaintDemo extends Applet implements MouseListener class extending applet component and implementing mouse event listener Here is an example showing how the repaint method is used in java: Now we will see some java examples showing the use of the repaint method: Example #1 Examples to Implement repaint Method in Java The whole idea behind the repaint method is to avoid the call to paint () method directly. Whenever the repaint method is invoked from a component, a request is sent to the graphical user interface, which communicates to the graphical user interface to perform some action at a future instance of time. When call to repaint method is made, it performs a request to erase and perform redraw of the component after a small delay in time. The repaint method is an asynchronous method of applet class. In case we have made changes to the appearance of a component but have not made any changes to its size, then we can call the repaint method to update the new appearance of the component on the graphical user interface.

Whenever we want a component to repaint itself, we need to call the repaint method. The repaint method is responsible for handling update to the paint cycle of the applet.

Whenever the repaint method is to be used, it should be directly called from the Applet class’s subclasses. is providing Java and Spring tutorials and code snippets since 2008. To create the countdown timer, we create a Timer object and call its method scheduleAtFixedRate (), which schedules and repeats the. We set the frame’s layout as FlowLayout () and set the position and size of the window. First add the body part for the text message in the email and then use FileDataSource to attach the file in second part of the multipart body. First, we create a jFrame object, then a jLabel that shows the text of the timer. To send a file as attachment, we need to create an object of and. The repaint method is a final method available in the Applet class, and that’s why it cannot be overridden. JavaMail Example send mail in java with attachment. Therefore repaint method can be directly called from a class extending Applet or its subclasses. The repaint method is a part of the class, and it cannot be overridden. The above syntax shows how a repaint method is used in java. Repaint() // calling repaint method when required
