in this peovram, the user should be able to hit enter multiple times to create a multiple lined sentence. The program should read all lines as one sentence and should only execute when there is a period.

for example, a sentence entered by the user can include:

(a) A windmill has six blades.

(b) A

windmill has

six

blades.

Write a program that will read in a line of text and output a list of all the letters that occur in the text, Jalong with the number of times each letter occurs. End the line with a period that serves as a sentinel value. The letters should be listed in alphabetical order when they are output. Use an array of base type int of length 26, so that each indexed variable contains the count of how many letters there are. Array indexed variable O contains the number of Ja's, array indexed variable 1 contains the number of b's and so forth. Allow both uppercase and lowercase letters as input, but treat uppercase and lowercase versions of the same letter as being equal. Hints: You will want to use one of the methods toUpperCase or to LowerCase in the I wrapper class Character as described in Chapter 5. You will find it helpful to define a method that takes a character as an argument and returns an int value that is the correct index for that character, such as 'a' returning 0, 'b' returning 1, and so forth. Note that you can use a type cast to change a char to an int, like (int)letter. This will not get the number you want, but if you subtract (int)'a', you will then have the right index. Allow the user to repeat this task until the user says she or he is through
