New to Java

I currently have a class that I need to extend and one method of that class that I need to override.

Assuming the following:

public BaseClass {}

public BarClass extends BaseClass {
    public configure () {}
}

public FooClass extends BarClass {
    @Override
    public configure () {
    }
}

I want to throw custom exceptions from FooClass, but haven't as yet found the magic behind doing that. If I add a throws statement to FooClass, eg.

public FooClass extends BarClass throws MyException{
    @Override
    public configure () {
        ...
        throw new MyException();
    }
}

javac complains that a "{" was expected on the FooClass declaration.

If I add the throws to the configure() method in FooClass, javac complains that the overridden class does not throw MyException. eg.

public FooClass extends BarClass{
    @Override
    public configure ()  throws MyException {
        ...
        throw new MyException();
    }
}

First, should I be able to throw my own exceptions on overridden methods of an extended class? If yes, what am I missing?
