What are the impacts of the final keyword on the string class in Java programming language?
n one of our team meetings one of our colleagues proposed the idea of extending the functionalities of the class called “stding” in Java so that we can add some custom methods. Now we are confused about the Challenges posed by the “final” keyword applied to the “string” class.
In the context of Java programming language, when a string class is final then it means that the class cannot be subclass or extended. It also means that it cannot be used as a superclass and it will further prohibit other classes from creating their version of the “string” class.
Here is the example given:-
// The String class in Java is declared as final
Public final class String {
// Class Implementation
// …
}
// An attempt to create a subclass of String (which is not allowed due to the final keyword)
// This code will result in a compilation error
// public class CustomString extends String {
// // Custom implementation
// // …
// }This above coding analogy showcases the impact of strings which are concluded as final in the Java programming language. This coding shows that if you try to create a subclass by using the final classes the class will show the result in the form of a compilation error.
