13. Access to object's type

Code that tests an object's type:

    Product p = new Book();  // create a Book object
    if ( p.getClass().getName().equals("Book") ) {
        System.out.println("This is a Book object");
    }

The console output:

    This is a Book object

An easier way to test an object's type:

    Product p = new Book();  // create a Book object
    if ( p instanceof Book ) {
        System.out.println("This is a Book object");
    }

The console output:

    This is a Book object
