The finally block is mainly used to close recourses for example when you make a Scanner object and you don't close it using the close method it could lead to memory leaks and that can be really bad when making big applications. You might be wondering doesn't execution just go to the next line after the catch block? Well yes it does but the key think about finally is that it always runs no matter what and this is useful especially if you were to change the program execution flow, that's the main advantage of finally is that it ignores you changing program execution flow and still runs whilst if you closed you recourses after the catch block without a finally block and the execution of your code changed, it'll still lead to memory leaks. Hope this helps
