string objects are cached in string pool.

Explanation:

Strings in Java are immutable or final because the string objects are cached in String Pool. As we know multiple clients share the string literals so there exists a risk of one client's action affecting all other clients.

For ex:-The value of string is "Roast" and client changed it to "ROAST" so all other clients will see ROAST instead of Roast.
