What is Multiple Inheritance?
Multiple inheritance is when a class inherits fields and methods from more than one parent class simultaneously, combining their behavior into a single subclas…
Abstract Class vs Interface: When to Use Which?
Use an abstract class when related types share common state and partial implementation you want to reuse, and use an interface when you only need to declare a…
What are Mixins in Object-Oriented Programming?
A mixin is a class designed to bundle a specific, reusable piece of behavior that is "mixed into" other classes, typically via multiple inheritance or composit…
What are Traits in Object-Oriented Programming?
A trait is a reusable, stateless unit of method implementations that can be composed into a class, similar in spirit to a mixin but with an explicit conflict-r…
Mixins vs Traits vs Interfaces: What is the Difference?
Interfaces declare a contract of method signatures with no implementation (in their classic form), mixins bundle reusable method implementations composed via i…
What are Default Methods in Interfaces?
A default method is a method in a Java interface that provides a concrete implementation using the default keyword, allowing implementing classes to inherit re…
What is the Diamond Problem in Multiple Inheritance?
The diamond problem is the ambiguity that arises when a class inherits from two classes that both inherit from a common base, and the compiler cannot determine…
How Does Java Avoid the Diamond Problem?
Java avoids the diamond problem for classes by permitting only single class inheritance — a class can extend exactly one superclass — while still allowing a cl…
What is an Interface Default Method Conflict?
An interface default method conflict happens when a class implements two or more interfaces that each declare a default method with the same signature, and the…
What is a Trait Conflict?
A trait conflict occurs when a class composes two or more traits (or mixins) that each define a method with the same name and signature, leaving the compiler o…
