What are the advantages and disadvantages of immutable string properties?

Immutable strings in Java have the following advantages:

• Safety and thread safety: since strings cannot be changed after creation, they can be safely used in multithreaded environments without additional synchronization.
• Caching and optimization: immutability allows JVM to use a string pool, saving memory and speeding up string comparisons.
• Ease of use: lack of side effects simplifies debugging and understanding code.

Disadvantages:

• Performance issues with modifications: each change creates a new object, which can lead to many temporary objects and increased garbage collection.
• Memory consumption: frequent creation of new strings increases memory usage.

For efficient handling of mutable strings, Java provides StringBuilder and StringBuffer classes.
