Yes, Interface mehtods are public by default so that they could be implemented by every class implementing the interfaces.
the default accessibility for interface is PUBLIC
This is not necessarily true. The only rules for this are that interface methods may not be private. They may be public, protected, or have the default (blank) access modifier.
All variables in an interface are by default public static and final and hence they are Constants.
by declaring in the header of the class: public/private interface [interfaceName] and do not write any method body(i.e. public void dance();)
Differences:Abstract class can also contain method definitions but an interface can contain only declarationsAll variables in an interface are by default public static and final whereas in Abstract class it is notAn interface can be considered as a pure abstract class that contains no method implementations and contains only declarations.
There is no such thing as an access specifier in Java. There are access modifiers.The default access modifier if unspecified is to allow access to classes in the current package only, except within an interface where the default is 'public'
A class is a data type. An interface consists of the private, protected and public members of a class, allowing consumers of the class to interact with the class representation in a controlled manner. The private interface is only accessible to the class itself and to friends of the class. The protected interface is similar to the private interface but is also accessible to derivatives of the class. The public interface is fully accessible. The private and protected interfaces are intended purely for use by the class implementers while the public interface is intended for use by both consumers and implementers.

The abstract keyword signifies that the particular method will have no features in the class where it is declared and it is upto the child class to provide the functionality. In case of an interface, the method is already abstract by default and has no code inside it. So there is no actual point in using the abstract keyword there.
Because an interface is like a contract/skeleton which decides what the implementing class has to do. So, if any entity in an interface is protected, they would not be available to the class that is implementing the interface. Hence, all the variables and methods declared inside an interface are public by default
