Letter histogram

Bonus: Fill in the following methods to print a histogram for which letters appear most often in the input text. Along the way, you will need to keep track of which letter (or letters) appear most often and how many times, then print the result at the end.

You can ignore all characters in the input text that are not letters from a-z or A-Z. Lowercase and uppercase letters should be counted as if they are interchangeable.

Tips:

Handle one letter at a time, proceeding from A to Z.

Implement and make use of the provided helper methods.

Keep track of the most common letters so far in a String variable, and update it as you go. You will also need to store how many times the most common letters you've seen so far appear in the text. What happens if the current letter's count is larger than the previous "best" count? What happens if it's equal to the previous best count?

Be sure to pass all the test cases and use good style. Javadoc comments and method stubs for the methods are provided. Do not modify the provided method headers.

Example input/output:

Enter the input text: The quick brown fox jumps over the lazy dog A|+ B|+ C|+ D|+ E|+++ F|+ G|+ H|++ I|+ J|+ K|+ L|+ M|+ N|+ O|++++ P|+ Q|+ R|++ S|+ T|++ U|++ V|+ W|+ X|+ Y|+ Z|+ Most common: O with 4 occurrences.
