Actually, java does not support multiple inheritance. You can achieve partial multiple inheritance using interfaces but java is not like C or C++ where you can do direct multiple inheritance. However, you can achieve partial multiple inheritance with the help of interfaces.
Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {…}
And this is under the assumption that Car and Automobile are interfaces.
Here if you see, though you don't inherit concrete code from the Car or the Automobile interface, you do inherit skeleton methods that determine the way your class eventually behaves and hence this can be considered partial Multiple Inheritance
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
Yes. Java does not support full fledged/proper multiple inheritance. But, whatever partial inheritance that Java supports can be implemented using interfaces Actually, java does not support multiple inheritance.

Interfaces are used in Java to accomplish most of the goals of Multiple Inheritance. For several reasons, Java only supports Single Inheritance for classes - i.e. a class can have only a single parent. The use of Interfaces is how Java attempts to implement most of the positives of the concept of Multiple Inheritance while avoiding its pitfalls.

Since an interface has no implemented methods, there is nothing to extend, since you would simply get empty method headings you can't make a class by extending an interface. An interface must be implemented, by filling in the method bodies. An interface is a tool to define common characteristics between classes, i.e. how they act. For instance, an interface might be used to define a window, a simple generic window: it opens, closes, breaks. Interfaces are useful to the client since you don't need to know the inner workings of the class to use it, for instance, as long as you know the data structure you are working with is a List, you don't need to know whether it is an ArrayList or LinkedList.
PHP Supports Multi Level Inheritance
Not all of them do; C++ uses multiple inheritance.The designers of Java decided to do away with several aspects of C++ that may cause confusion, this includes multiple inheritance, pointers, and several other aspects.The possible confusion with multiple inheritance arises when both parents have a method or field with the same name. Which one to use in the child?To have some of the benefits of multiple inheritance, Java supports interfaces instead. A class can implement multiple interfaces.
Inheritance is a Java feature by which we can reuse code and programming logic from one class in another class. We implement Inheritance using the extends keyword.Ex: public class Ferrari extends Car {…}Here the Ferrari Class will extend features from the Car Class.This is Inheritance. The different types of Inheritance are:Single InheritanceMulti-Level InheritanceMultiple Inheritance (Java supports only Partial Multiple Inheritance) andHybrid Inheritance
In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
Let me explain with a example. Suppose consider a method funX() which is in class Z. Suppose a programmer ABC inherited the class Z to class X and overrided the funX().So this class will have the new implementation of funX(). Suppose a programmer DEF inherited the class Z to class Y and overrided the funX().So this class will have the new implementation of funX(). If Multiple Inheritance is permitted in java, then if the new programmer inherited both the classes and he didn't done any overriding of method funX() then if he calls the funX() ,the JVM will not know which method to call i.e., either the method in class X or method in class Y. Because of this inconsistencies,Multiple inheritance is not permitted in java.
Yes.
