Difference between abstract class and interface in java

Let’s learn difference between abstract class and interface in java.

Here’s the difference between abstract class and interface.

abstract class	interface
have instance methods that implements default beahviour.	methods are implicitly abstract. No implementation.
may have non final variables.	variables declared are by default public, static and final.
members are protected, private etc.	members are public by default.
abstract class can be extended using keyword “extends”.	interface can be implemented using keyword “implements”.
abstract class can extend another java class and implement multiple interfaces.	interface can only extend another interface.
cannot be instantiated. can be subclassed.	absolutely abstract; cannot be instantiated
