An Adapter class is just a "blank" implementation of a Listener interface. They're convenience classes made so you don't need to implement all of the methods of an interface.
A good example is the MouseListener interface. Let's say you want to detect when a user clicks on your Component. You only need to implement the mouseClicked method to get that part working. This will leave you with...
public void mousePressed(MouseEvent e) {
}
public void mouseReleased(MouseEvent e) {
}
public void mouseEntered(MouseEvent e) {
}
public void mouseExited(MouseEvent e) {
}
...at the end of your implementation. Ugly. So Java gives us the MouseAdapter class (which gives us the same empty implementations as above). We can use this in place of a MouseListener to try to keep our code cleaner.
When using a listener you have to implement all the methods that the class provides. An adapter has already implemented empty methods and you can only implement those you need. It is mostly quality of life.
The difference between the Class 365 and Class 465, 466 is basically the cost.
class III rated for up to 5,000lbs, class IV is rated for up to 10,000lbs towing capacity
The main difference is the thickness of the pipe Compare to A Class pipe B Class pipe thickness is more.Like that Compare to B class pipe C Class pipe thickness is more.
because it gets to mailer faster
An adapter pattern is a structural design pattern which translates one interface for a class into a compatible interface.

What is the difference between buying a 1st class and a 2nd class ticket on the train in England?
class III rated for up to 5,000lbs, class IV is rated for up to 10,000lbs towing capacity
No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.

The adapter method is when you create a class which wraps around another (holding that other class as a variable). The adapter class then responds to calls by calling the methods of the held variable.
