Is Parenthesized

Write a static method that will receive two Strings, a needle and a haystack. The method should return true if the needle is found surrounded by parentheses.

Your solution must use either .substring() or .indexOf().

Preconditions:

• The needle String won't be null and will length 1 or greater.
• The haystack String won't be null and will be at least two characters longer than the needle.

Examples:

• isParenthesized("cat", "(cat)") returns true
• isParenthesized("cat", "There's a (cat) here") returns true
• isParenthesized("cat", "There's a )cat) here") returns false
• isParenthesized("cat", "There's a (dog) here") returns false
• isParenthesized("X", "Xx(X)xX") returns true
