String and Character Array in Java

Question

I am a student who has just shifted from C++ to Java.

In Java what could be the main reason for defining separate data types for Strings and Char arrays? Wha

Answer 1

String is immutable in Java and stored in the String pool. Once it is created it stays in the pool until garbage collected.Since, String is immutable , the logging password is as readable string.It has greater risk of producing the memory dump to find the password.

where as Char array is created in heap and you can override with some dummy values.
