Strings are immutable in Java primarily for performance and security reasons. Immutability ensures that once a string object is created, its value cannot be changed. This simplifies memory management and optimization by allowing strings to be shared and reused, rather than creating new objects every time a modification is made. Additionally, immutability enhances security by preventing unintended changes to sensitive data, as strings are often used to store passwords, API keys, and other confidential information. read less

The reason of making string final is to destroy the immutability and to not allow others to extend it. The String objects are cached in the String pool, and it makes the String immuta...

Strings are immutable in java. First let's understand what immutable means... Immutable means which can not be changes. In Java When strings are created they are allocated some memory space and they have address in memory so If we try to modify in string then new string is created and it referes to new memory allocation and old memory is elligible for garbage collection if there is no reference to that memory location thats why strings are immutable, once created they can not be changes rather new string with new memory is allocated.

It we are using new while creating string object so everytime it will use new memory allocation. If assign two same string literal to two reference they point to same memory location. Benifit of this performance improvement.
