practice JAVA program that inputs a string from the user and prints a copy of the string with the first character of each sentence capitalized. (No need to consider strings with punctuation marks other than a period.) NOTE: For string and character manipulation, you should use only the String and Character methods (and not methods of other API classes) HINT: To split a string with “. “ delimiter, pass the following expression to the split method: “\\. “ String methods split, charAt, and substring, and Character method toUpperCase can be helpful.
