The answer is No, interface cannot have constructors. In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).Click to see full answer. Similarly, you may ask, why we Cannot create a constructor to an interface?Interfaces in Java don’t have constructor because all data members in interfaces are public static final by default, they are constants(assign values at the time of declaration) . There are no data members in interfaces to initialize them through constructor.Also Know, cAN interfaces have method declarations? Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final ). All methods of an Interface do not contain implementation (method bodies) as of all versions below Java 8. Likewise, people ask, what happens when constructor is defined for an interface? Explanation: Constructor is not provided by interface as objects cannot be instantiated. 9. What happens when we access the same variable defined in two interfaces implemented by the same class?Can we declare constructors as final?No Constructors can NEVER be declared as final. Your compiler will always give an error of the type “modifier final not allowed” Final, when applied to methods, means that the method cannot be overridden in a subclass. Constructors are NOT ordinary methods. So there is NO SENSE in declaring it final.
