Compiler doesn't complain when I ended a line with two semicolons. Why?

Question

I thought bad thing would happen when I ended a line like this. But compiler didn\'t even complain. Does anybody have an idea, why this is legal in java.

Answer 1

The compiler uses semicolon to denote an 'end of statement'. Having two consecutively ends the statement prior to the first, and then creates a second empty statement.

Really, you could even do this:

displayDataMap.put("dateInterval", getDateInterval());;;;;;;;;;;;;;;
