In Multiple Inheritance a class can inherit behavior from more than one parent classes.
Prior to Java 8, a class can implement multiple interfaces but extend only one class.
In Java 8, we can have method implementation within an interface. So an interface behaves like an Abstract class.
Now if we implement more than one interface with method implementation in a class, it means we are inheriting behavior from multiple abstract classes. That is how we get Multiple Inheritance in Java 8.
