Interview Questions and Answers for 'Amura marketing technologies' - 1 question(s) found - Order By Newest

 Q1. Why Char array is preferred over String for storing password?Core Java
Ans. String is immutable in java and stored in String pool. Once it's created it stays in the pool until unless garbage collected, so even though we are done with password it's available in memory for longer duration and there is no way to avoid it. It's a security risk because anyone having access to memory dump can find the password as clear text.
