Which Expression:

Write a method that takes a String as a parameter and prints to the screen which of the regular expressions shown below is satisfied by the String. The String can only contain the characters a and b and you must use the.matches(<...>) method with a regular expression. The method doesn't have to return anything.

 

Regular Expression No.                 Regular Expression

1:                                                         a(b|a)b

2:                                                        (ab)* b

3:                                                        a(b|a)*

4:                                                        ( (a|b) a)*

If the String satisfies more than one regular expression print each one on a new line. See output below. If the String does not satisfy any expression have a valid print statement stating this fact. In your main method call the method with user input.
