Inheritance is one of the building blocks of Java and it is used extensively in all java based applications. Inheritance is everywhere in Java. I can't think of one java project that I worked on, where inheritance wasn't used.
Inheritance is the feature wherein the properties/qualities of a parent class or interface is used in the child class. Both Classes & Interfaces are used in Java Inheritance

How can you write multiple inheritance program in java?
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
What does java not support?
Java does not support multiple inheritance.......
Give the structure of multiple inheritance?
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
Why you neet interface in java?
When you need the benefits of multiple inheritance while avoiding the DDD (Deadly Diamond of Death). Java doesn't allow multiple inheritance anyway.

What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
What kind of inheritance is not allowed in java?
Java does not allow the multiple inheritance of concrete classes, though it does allow a "hybrid" inheritance of one concrete class and multiple interfaces.

What do you mean by multithread program in java?
A Program in Java that spawns multiple threads is called a multithreaded program in Java.
Can we implement multiple inheritance in java using package and interface?
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. 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.
Need of interface in java?
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.
What is multiple inheritance in java?

Can a single Java class subclass extend both InputStream and Reader. True or False?
Java does not have multiple inheritance, so no. Java can use multiple interfaces, though, with the "implements" keyword.
How interface supports indirect multiple inheritance in java?
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.

Why not java allowed multiple inheritance and c plus plus allowed?
Because that's the way Java is designed. The designers felt that multiple inheritance was an unnecessary complication that offered little value so they did not include it in the JBC/JVM.
What types of inheritance in Java programming?
Java uses a hybrid system of inheritance. The designers chose a compromise between strict single inheritance and full multiple inheritance.See the related questions section below for more information.
Multiple inheritance in java?

However, you can achieve partial multiple inheritance with the help of interfaces. Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {
How do you implimenting multilevel inheritance in java?
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.
