The code between the start-tag and end-tag will be processed for the 1st subvariable, then for the 2nd subvariable, then … It can be used to terminate a case in the switch statement (covered in the next chapter).. Syntax. However, every design decision has trade-offs and polymorphism can be used as a counter-argument against marker interfaces.
