Number 4 in Java please

a * * * * . . * * e * * * 4)(10 points) In your main you should test a letter frequency analysis out on some arbitrary text. (See the example to the right.) This requires createLetter Histogram to generate a histogram normalizeArray to normalize the letter frequencies Create a label array with each letter in it b drawHistogram to visualize the resulting frequencies d * String vText = "Voila! In view, a humble vaudevillian veteran, cast vicariously as both victim and villain by the vicissitudes of f Fate. This visage, no mere veneer of vanity, g is a vestige of the vox populi, now vacant, vanished.

You should go download two books in different languages and see if the language frequency looks different. Get books here: t * * u * V * * W http://www.gutenberg.org/ Save the Plain Text (UTF-8) or similarly named file as a .txt in the BlueJ project folder. Then use the helper code below to load that into a String for you to generate the letter analysis. Z
