Write a function in JAVA that takes 2 numbers in string and forms a string containing the addition of these 2 numbers?

Assumption:

The input strings will contain only numeric digits
The input strings can be of any large lengths
The lengths of the two input string need not be the same
The input strings will represent only positive numbers

Example

If input strings are “1234” and “56”, the output string should be “1290”
If input strings are “56” and “1234”, the output string should be “1290”
If input strings are “123456732128989543219” and “987612673489652”, the output string should be “123457719741663032871”
