Using Java: Write a program that asks the user to enter a sentence. Using matches method using only one pattern validate that the entered sentence consists only of letters and ends with either: a period, an exclamation mark, or a question mark. To check if the given string represents a valid sentence define a pattern. If it is not a valid sentence, your program should output that the input is not valid.
