Create an application that will compute the average of a list of numbers. Begin with two windows. The first window, titled “Display,” should have a label and a vertically scrollable text area. The second window, titled “Data entry,” should have a text field and an Enter button. When a user enters an integer value into the text field and clicks the Enter button, copy the value in the text field to the text area in the display window. Also, update the label in this window to indicate the number of values, their sum, and average. If either window is closed, quit the application.

What will be an ideal response?

See the code in ComputeAverage.java.
