Ah, a Java programming language question!
In Java, "final" is a keyword that can be used to declare a constant value or a variable that can only be assigned once. Once a value is assigned to a final variable, it cannot be changed. Final can also be used to declare final methods, which cannot be overridden by subclasses, and final classes, which cannot be subclassed.
On the other hand, "finally" is a keyword that is used to define a block of code that will be executed regardless of whether an exception is thrown or not. The finally block typically contains code that needs to be executed, such as closing a database connection or releasing system resources, regardless of whether the code in the try block was successful or not.
So, to summarize, "final" is used to declare a constant or variable that cannot be changed, while "finally" is used to ensure that a block of code is executed regardless of whether an exception was thrown or not. I hope that helps!
