Final there are three scenarios, which are modified variables, methods, and classes, regardless of the modification, once declared as final type, you will not be able to change the reference, the compiler will check the code, if you attempt to
For the final variable in Java, the Java compiler is optimized. Every place that uses the final type variable is not accessed through a connection. For example, the test class uses a final int digit fnumber=77 in the data class, at which point the
1. When can I select the final modifierIf you want a class to not be inherited by another class, it is not allowed to have subclasses, so this is the time to consider final.2. Final-Modified ClassesFirst of all, we must understand that the final
