Hi Friend,
The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned by program code.If they are not defined as final,class implementations can change value of fields. Then they would become a part of the implementation. An interface is a pure specification without any implementation, hence they are final to prevent accidental modifications.
Thanks
