If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.2. If the year is evenly divisible by 100, go …

The program then calculates the sum and displays it. Using Python Using javascript
Continue reading Program to Add two NumbersWhen JVM starts up, it creates a heap area which is known as runtime data area. This is where all the objects (instances of class) are stored. Since this area is limited, it is required to manage this area efficiently by removing the objects that are no longer in use. The process of removing unused …
Continue reading Garbage Collection in Javafinal keyword can be used along with variables, methods and classes. 1) final variable final variables are nothing but constants. We cannot change the value of a final variable once it is initialized. Lets have a look at the below code: Note: It is considered as a good practice to have constant names in UPPER …
Continue reading Final Keyword In JavaYou must have seen public, private and protected keywords while practising java programs, these are called access modifiers. An access modifier restricts the access of a class, constructor, data member and method in another class. In java we have four access modifiers: 1. default 2. private 3. protected 4. public 1. Default access modifier When …

What is encapsulation? The whole idea behind encapsulation is to hide the implementation details from users. If a data member is private it means it can only be accessed within the same class. No outside class can …
Continue reading Encapsulation in JavaA class that is declared using “abstract” keyword is known as abstract class. It can have abstract methods(methods without body) as well as concrete methods (regular methods with body). A normal class(non-abstract class) cannot have abstract methods. An abstract class can not be instantiated, which means you are not allowed to create an object of …
