Question

I have a file named "Class.dat" with me, doubtly it can upload here. But please help with this coding by using only JavaFX. Thank you!

Problem 1: Inner Classes (60%) Read all of problem 1 before starting, hints are given throughout the problems statement. See the Execution Examples, below, to see what the GUI should look like Overview Fields and Behaviors: Behavior GUI Component TextArea Will hold the text being searched. It needs to be updated when a word is found This area is horizontal and vertical scrollable Holds the word to be found Every time this button is pressed, the first occurrence of the "find" word in the TextArea will be located and highlighted A named inner class. Clears the TextField that holds the word to match Sets the input focus to the 'find' text field This does NOT clear the text area. An Anonymous inner class. Close using window listener/adapter inner class, and print a "Thank you for using finder" message An Anonymous inner class. Add a WindowListener using WindowAdapter class formatted similar to an ActionListener TextField Find Button Clear Button Windows close Requirements: 1. You need to develop your own inner classes to handle the events. You must handle the window closing and button press events 2. The search is case sensitive. If the case of the letters in the word in the TextArea does not match exactly the word in the TextField, skip over it Page 1 of5
