Hybrid Inheritance in Java with Example
Hybrid Inheritance is a combination of both Single Inheritance and Multiple Inheritance. Since in Java Multiple Inheritance is not supported directly we can achieve Hybrid inheritance also through Interfaces only. … [Read more...]
Hierarchical Inheritance in Java with Example
In this inheritance multiple classes inherits from a single class i.e there is one super class and multiple sub classes. As we can see from the below diagram when a same class is having more than one sub class (or) more than one sub class has the same parent is called as Hierarchical Inheritance. … [Read more...]
Multilevel Inheritance in Java with Example
In Java Multilevel Inheritance sub class will be inheriting a parent class and as well as the sub class act as the parent class to other class. Lets now look into the below flow diagram, we can see ClassB inherits the property of ClassA and again ClassB act as a parent for ClassC. In Short ClassA parent for ClassB and ClassB parent for ClassC. … [Read more...]
Multiple Inheritance in Java Example

No, We cannot Override a static method in Java. Unlike Overloading of static method we cannot do overriding. When we declare a method with same signature and static in both Parent and Child class then it is not considered as Method Overriding as there will not be any Run-time Polymorphism happening. … [Read more...]

Java Method Overloading is one of the feature in OOPs concept which allows you to have two or more methods with same method name with difference in the parameters in other words, we can also call this phenomena as Compile time polymorphism. … [Read more...]

Encapsulation in Java with Example
Encapsulation in Java is the process of wrapping code and data together into a single unit. Encapsulation hides the implementation details from the users. If the data member is private then it can be accessed only within the same class . No other outside class can access the private member of other class. … [Read more...]
