Is it possible to extend from the Java Lang String class?
You cannot extend a class that is marked as final. You can use composition to either put a String object inside or you can hand roll your own version. This can be accomplished via character arrays and the other magic that goes into creating String classes.
Why String class is final or is it not?
The string is immutable means that we cannot change the object itself, but we can change the reference to the object. The string is made final to not allow others to extend it and destroy its immutability. Class loading String is used as arguments for class loading.
Why String is final or immutable in Java?
The String is immutable in Java because of the security, synchronization and concurrency, caching, and class loading. 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 immutable.
Which package is the String class in?
