How many interfaces can a class inherit?
Consequently, how many classes can any class inherit how many interfaces can a class implement?
But if you really really want to know the theoretical maximum number of interfaces a class can implement, it's 65535.
Likewise, can a class inherit multiple interfaces in Java? Extending Multiple Interfaces A Java class can only extend one parent class. Multiple inheritance is not allowed. Interfaces are not classes, however, and an interface can extend more than one parent interface. The extends keyword is used once, and the parent interfaces are declared in a comma-separated list.
In this way, cAN interfaces inherit from classes?
The class that implements interface must implement all the methods of that interface. To implement the above interface, we can have: Also, it is possible for a java interface to inherit from another java interface, just like classes can inherit from other classes. You specify inheritance using the extends keyword.
Can a class implements multiple interfaces?
A Java class can only extend one parent class. Multiple inheritance ( extends ) is not allowed. Interfaces are not classes, however, and a class can implement more than one interface. The parent interfaces are declared in a comma-separated list, after the implements keyword.
