[Solved]Create Design Pattern Table Show Parts Observer Pattern Realized Given Java Code Example B Q37280486

create a design pattern table to show how the parts of theobserver pattern are realized in the given java code. An examplefrom the book is listed as well.
This question concerns the Observer design pattern discussed in the textbook and in class In GUI design, aslder is a component that allows the user to specify a value from a continuum of values by dragging an indicator. In Swing, sliders are added to the interface by creating objects of type javax.swing.JS1ider. GUI components that want to take an action when the user drags the slider can do so by putting the action inside an object that implements the ChangeListener interface, and then adding the listener object to the slider public interface ChangeListener public void stateChanged (ChangeEvent e) The JS1ider object calls the stateChanged ) method of the attached ChangeListener object whenever the user moves the slider. Here is a segment of code that changes the contents of a text field each time the user drags the slider final JSlider theSlidernew JSlider (MIN, MAX) final JTextField textField new JTextField (“0”) theSlider.addChangeLi new ChangeListener ( stener ( public void stateChanged (ChangeEvent e) /getValue) return:s an int, which we a String. slider.getValue ) (sliderPos.tostring )) want to turn into Integer sliderPos textField.setText Make a table like the one we constructed in class for other design patterns. Your table should show how the parts of the Observer pattern are realized in the code above. You can see an example of such a table for the Iterator pattern on page 179 of the textbook 179 5.2 The Patten Concep For example, in the case of linked list iterators, we haver Actual Mame Rame In Design Patio Aggregate ConcreteAggregateikist Iterator ConcreteIterator Ananonymous class that implements List ListIterator the ListIterator interface type createlteratorO TistIteratorO nexto isDone O currentItemO nextO Opposite of hasNext O Return value of nextC tial book, Design Patterns by Gamma, Helm, Johnson, and Vlissides, con- The influent tains a description of many patterns for software design, including the ITERATOR pattern.
