In Java, the String class is a prime example of a final class; and it's marked as final to ensure that its immutability and security properties are maintained. This design choice prevents any subclass from altering the behavior or compromising the integrity of String objects, allowing for performance optimizations and safe usage across multiple threads. The final keyword plays a critical role in maintaining these properties by prohibiting the extension of the String class.
