Develop a simple tool for calculating some basic statistics about a segment of text. Your finished program should look as similar as possible (or better!) than the sample shown below.

The application should have a single window with a scrolling textbox (see JTextArea) and a statistics box. The statistics box should be a panel with a titled border. This box should contain labeled fields that display the following statistics:

? The number of words in the textbox

? The average word length

? The number of vowels

The statistics box should also contain a button. When the button is pressed, your application should re-compute the statistics for the current contents of the text field.

Feel free to display extra statistics than the ones currently shown.

Tips:

Remember you can nest panels.

Use layout managers.

You can wrap the text in a JTextArea using the method setLineWrap(true).

To match on non-alphanumeric characters: "\\W+"

Do not place all of your code into the constructor and the event listener. Use good OO thinking to break your

program into small pieces
