Introduction

To throw an exception in a method, add the throws keyword after the method's closing parenthesis.

Here's an example: 

public void getPoint (int x, int y) throws NumberFormatException { 
}

If your method might throw multiple types of exceptions, declare them all in the throws clause separated by commas: 

public void storePoint (int x, int y) throws NumberFormatException, EOFException { 
}

You can use a superclass of a list of exceptions to tell that your method might throw any subclass of that exception.

For instance: 

public void loadPoint () throws IOException { 
}
