Your task is to write a complete Java program that takes in a single line with an integer between 0-100 (inclusive) as input. This integer represents a person's age. The program should then print a message that tells the person which life stage they are in based on the following conditions:
If the person's age is less than 12 (inclusive), print 'Child'.
If the age is between 13 and 17 (both inclusive), print 'Teenager'.
If the age is between 18 and 59 (both inclusive), print 'Adult'.
Lastly, if the person's age is 60 (inclusive) or above, print 'Senior Citizen'.
