Question 143 Explanation:
● The interface in java is a blueprint of a class. It has static constants and abstract methods.
● There can be only abstract methods in the Java interface, not method body.
● It cannot be instantiated just like the abstract class because there is no method definition available with the interface.
● There can be only abstract methods in the Java interface, not method body.
● It cannot be instantiated just like the abstract class because there is no method definition available with the interface.
