The throw statement

To throw an exception, we use the throw statement.

Throwing an exception

Syntax:

throw exceptionObject;

• exceptionObject is an object of the class Exception (or of one of its subclasses)

Semantics:

Throws an exception of the type indicated by the object appearing as parameter to the throw statement.

Example:

throw new MyException("message for MyException");

This statement throws an exception of type MyException, which prints on the screen the message that appears as parameter to the constructor.
