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: GUI Component Behavior TextArea Will hold the text being searched. It needs to be updated when a word is found. This area is horizontal and vertical scrollable. TextField Holds the word to be found Find Button 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. Clear Button 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. Windows close Close using window listener/adapter inner class, and print a "Thank you for using finder" message. An Anonymous inner class. Add a Window Listener using Window Adapter class formatted similar to an ActionListener. 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 of 5 3. You only need to locate the first occurrence of a string of text. Use ONE of the string methods for this 'find' (look up the indexof method of the String class). 4. The Find operation is able to find text such as in this sentence, "this sentence should be found. Execution example: (screens shrunk) Loaded the text area with text Entered "find" and pressed the from this assignment. Notice the find button. Notice it skipped word "Classes" in the first line.

If you like, you can set the selected text color from gray to another color, such as red or blue. But this requires the use of CSS, which you may or may now know about, so this is not required.
