What is multiple inheritance in Java with example?
When one class extends more than one classes then this is called multiple inheritance. For example: Class C extends class A and B then this type of inheritance is known as multiple inheritance. Java doesn’t allow multiple inheritance.
What is multiple and multilevel inheritance in Java?
The difference between Multiple and Multilevel inheritances is that Multiple Inheritance is when a class inherits from many base classes while Multilevel Inheritance is when a class inherits from a derived class, making that derived class a base class for a new class.
What is multilevel inheritance explain with example?
When a class extends a class, which extends anther class then this is called multilevel inheritance. For example class C extends class B and class B extends class A then this type of inheritance is known as multilevel inheritance.
Which case has multiple inheritance in Java?
Java supports multiple inheritance through interfaces only. A class can implement any number of interfaces but can extend only one class.
Can we achieve multiple inheritance?
The only way to implement multiple inheritance is to implement multiple interfaces in a class. In java, one class can implements two or more interfaces. This also does not cause any ambiguity because all methods declared in interfaces are implemented in class.
Why does Java not support multiple inheritance?
java does not support multiple inheritance because it does not meet object oriented specification. Due to ambiguity problem will arise if two or more superclass have the same method name, and the super keyword will not be able to decide which superclass to call. so we use interface to solve this problem.
Why is multiple inheritance not allowed in Java?
Multiple Inheritance for classes is not supported in Java, but it does support multiple inheritance for interfaces. Main reason for not allowing multiple inheritance for classes is Deadly diamond of Death pattern( also known as DDD).
Why no multiple inheritance in Java?
Hence, Java does not support multiple inheritance because it can lead to increased complexity and ambiguity in case of ‘ Diamond Problem ‘ which means that when classes with same signature in both the parent classes are made and child class when on calling the method makes the compiler cannot determine which class method to be called and this causes diamond problem and gives the compile time Error.
Why multiple inheritance is not possible in Java?
Why Multiple Inheritance is not supported in Java? Java doesn’t support multiple inheritance in order to reduce complexity in code and to simply the Java programming language. If both parent class will have a method with the same name then, in that case, the compiler will not be able to decide which method to invoke.
