Any class you create will inherit from another class - either explicitly, if you use the extends keyword, or implicitly from the Object class. This is single inheritance, since you can't inherit from more than one class. Here are two examples:
public class MyClassA
{
...
}
public class MyClassB extends MyClassA
{
...
}
In the above examples, MyClassA implicitly inherits from Object, and MyClassB explicitly inherits from MyClassA.

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 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.
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.
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.
Specification forms of inheritance in java?
single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
What does java not support?
Java does not support multiple inheritance.......
What is ambiguity in multiple inheritance?
Java does not support multiple inheritance
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 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.
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.
What is public inheritance in java?
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
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.
