throws Keyword

The throws keyword goes in a method signature and declares that the method can propagate one or more exceptions to its caller without catching them. The previous lesson covered throw, which is a statement inside a method body that raises an exception right now. throws is the other half of the picture: it announces, as part of the method's contract, that calling this method might result in one of these exception types being thrown. This lesson covers the syntax, the compiler's "handle or declare" rule for checked exceptions, how throws interacts with method overriding and interfaces, and when listing an unchecked exception is worth the noise.
