Hey guys,
Looks good enough. "More elegant" ways to do that would usually imply to use a List rather than an array.

Adding character/s to a string has two different variations.
If you apply operator + on two number operands, then it is addition. And chars are seen as numbers. So it adds '[' and '[', which is 182. Then it concatenates 182 with "eeksforGeeks"

Adding character/s to a string has two different variations.
If you apply operator + with any of its two operands being a non-wrapped object, then it is concatenation. It will produce a String which is the result of converting operands to String as needed, and then producing the String that is the first operand's String immediately followed by the second's.

Adding character/s to a string has two different variations.
That's an unfortunate result of the fact that operator + may mean addition or concatenation

Jackson Mapper - String[] conversion possible?
.... No. Jackson does the job it is expected to do. Whether internally arrays or lists are involved is none of the business of whoever isn't making Jackson itself.

Jackson Mapper - String[] conversion possible?
Jackson is for converting to JSON, not to arrays. What can possibly make it so you care whether that convert above will give out an array or a List?
