CST$242$ Advanced Programming Using Java March $15,2024$ In publishing, advertising and related fields, the word $$copy$$ refers to written material in books, magazines, newspapers and advertising. Create a JavaFX application as per the image below in the form of a $$Copy Editor$$ application with $$Search and Update$$ functionality. When the application runs, the user sees text in the window that may need editing. The window should contain one TextArea, two TextField$$s and two Button$$s$.$ First create a TextArea with the text in the image above already displayed. This is the $$copy$$ text to be edited. Use the setEditable method to set that property to false so the user cannot type in the TextArea and the setWrapText method to set that property to true so the text wraps from line to line. The two TextField$$s allow the user to type the search string and the update string $($place appropriate place Label$$s above these two TextFields$).$ The Button$$s are the $$Search$$ button and the $$Update$$ button. Create event handlers that respond to these two buttons. If the user clicks the $$Search$$ button, use string manipulation techniques to determine if the $$search$$ substring is located within the $$copy$$ string from the TextArea. If this is true, display the location $($the index$)$ of the $$search$$ substring within the $$copy$$ string in a showMessageDialog$().$ Otherwise display a $$Not Found$$ error message. If the user instead clicks the $$Update$$ button, use string manipulation to determine if the $$search$$ substring is located within the $$copy$$ string. If this is true, use the contents of the $$update$$ string TextField to replace the found string within the TextArea. If the $$search$$ string is not found within the TextArea, show a $$Not Found$$ error message in a showMessageDialog$().$ Both buttons in this application begin by looking for the $$search$$ substring within the TextArea and display an error message in a showMessageDialog$()$ if it is not present. In one way or another, implement this task in your application so that it is coded just once. For full credit, create and use for all the event processing above a programmed$-$defined class $$SearchAndUpdate$$ with two String instance variables copyString and searchString. The single constructor takes two String parameters $($when instantiating the object, pass to the constructor the values from the $$copy$$ TextArea and the $$search$$ TextField$)$ and assigns them to the two instance variables by calling the set methods $($see below$).$ The additional class methods are: $1.$ Set methods for the two instance variables $($in the set method for searchString create and use a programmer$-$defined exception class EmptyStringException that extends from the Java API class $$Exception$$ to validate that the $$search$$ TextField is not blank; catch this exception in the event handler or handlers$)2.$ Get methods for the two instance variables $3.$ A method search$()$ of type int that performs the $$search$$ processing and returns the index of the $$search$$ substring within the $$copy$$ string, or a default value $-1$ if not found $4.$ A method update$()$ of type String that performs the $$update$$ processing and returns an updated String with the $$update$$ string substituted in the $$copy$$ string $($this method uses method search$()$ from above to validate that the $$search$$ string is located within the $$copy$$ string$)$ For partial credit you may eliminate any of the following: $1.$ The programmer$-$defined class $$SearchAndUpdate$(10$ point reduction$)2.$ The update functioning$$only implement the search functioning $(15$ point reduction$)3.$ The exception handling with the class EmptyStringException $(7$ point reduction$)4.$ Or eliminate both the update and search functioning as well the programmer$-$defined class and the exception class, and only draw the JavaFX form $(40$ point reduction$)$
