Question

Write a program in Java that computes the number of words in a text entered in a text field. Use the following graphical objects:

• a text field for the input text (one line of text)
• a button that, when pressed, computes the word count
• a button that, when pressed, clears the text field
• labels for the input and output and for showing the word count

Requirements and Restrictions: Choose proper background, color, and layout and arrange the graphical objects exactly as shown in the example below. Make sure the layout does not change when resizing the window.

Extra credit (maximum 2 points) will be given for additional text statistics (for example, maximum, minimum and average word size, number of numeric tokens, word frequencies etc.).
