The throws keyword is used to create a list of checked exceptions that are not handled in the code block of either a method or a constructor. A method or constructor does not need to specify any unhandled unchecked exceptions in the throws list.
The throws list must be after the method or constructor signature and before the opening curly brace of the code block:
( return type ) ( methodName(parameter list) )( throws ) ( ExceptionClass ) { method body }

Java exception handling has a principle called the catch or specify requirement that applies to checked exceptions. A method or constructor body that invokes a method or a constructor that throws a checked exception must either handle that exception with a try/catch statement, or specify that checked exception in the throws list.
