Interface multiple inheritance &&byte&& abstract classes

First, abstract class

An abstract class can implement an interface if implementing an interface must implement a method in the interface

Second, byte

Byte (byte), which is the meaning of a bit, is often used to denote the following:

1tb=1024gb
1gb=1024mb
1mb=1024kb
1kb=1024byte
1byte=8bit (BIT)

Third, interface multiple inheritance

In Java design, class can only inherit single, but interface can be multiple inheritance, the example is as follows:

1 interface Monster {2     void menace (); 3} 4  5 interface Dangerousmonster extends Monster {6 void Destroy (); 7 } 8  9 interface Lethal {ten void Kill ();}12 interface Vampire14 extends Dangerousmonster, lethal {void dri Nkblood (); 16}
