Write a static method called flip2 that takes an ArrayList of Strings as a parameter and then flips each successive pair of values in the list. For example, suppose that a variable called list stores the following sequence of values: ["aa", "bb", "cc", "DDD", "happy", "snow"] and we make the following call: flip (list); Afterwards the list should store the following sequence of values: ["bb", "aa", "DDD", "cc", "snow", "happy"] If the list has extra values that are not part of a pair, those values are unchanged. For example, if the list had instead stored: ["aa", "bb", "cc", "DDD", "happy", "snow", "hometown"] The result would have been: ["bb", "aa", "DDD", "cc", "snow", "happy", "hometown"]

Question
![Write a static method called flip2 that takes an ArrayList of Strings as a parameter and then flips each
successive pair of values in the list. For example, suppose that a variable called list stores the following sequence
of values:
["aa", "bb", "cc", "DDD", "happy", "snow"]
and we make the following call:
flip (list);
Afterwards the list should store the following sequence of values:
["bb", "aa", "DDD",
"cc", "snow", "happy"]
If the list has extra values that are not part of a pair, those values are unchanged. For example, if the list had instead
stored:
["aa", "bb", "cc", "DDD", "happy", "snow", "hometown"]
The result would have been:
["bb", "aa", "DDD",
"cc", "snow", "happy", "hometown"]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc4247586-c5ba-4193-bff0-fd146d066f71%2F8cad6626-859f-4484-9cf4-64240e49026d%2Flj8ktgk_processed.png&w=3840&q=75)
