How do you serialize a string into a list in Java?

Question

I want to convert a string say "98989" into an integer without using any library functions in java. Give fastest way to do it and explain why your method is best.

Answer 1

All standard implementations of java.util.List already implement java.io.Serializable and java.util.List itself is not a subtype of java.io.Serializable,it should be safe to cast the string into a list to Serializable, as long as we know it's one of the standard implementations like ArrayList or LinkedList.
