Basically, the constructors in Kotlin can be categorized as the Primary Constructor and the Secondary Constructors. In other words, a class in Kotlin can have a primary constructor and one or more secondary constructors. Creating Constructors in Kotlin While a class in Kotlin can have one primary constructor, it can include several secondary constructors. For the purpose of creating secondary constructors, we need to use the […]

In this article, I will explain how to create Classes in Kotlin. Like other programming languages, the class keyword is used to define a class in Kotlin. Moreover, classes in Kotlin can have properties, methods, and constructors as its members. The following code shows the syntax of creating classes in Kotlin. Unlike Java, it is not mandatory to have classes in a Kotlin program. […]
In this article, I will demonstrate several examples of the Variable Declaration in Kotlin. As a matter of fact, Kotlin was developed for Java Virtual Machine (JVM). Therefore Java and Kotlin are interoperable. Further, Kotlin has been used for Android app development. In general, Kotlin creates variables in two ways – using the val, and var keywords. While variables declared with val keyword are […]

In general, there are many features of Kotlin that will motivate you to adopt Kotlin as the programming language in Android development. Evidently, in 2017 Google announced its support of Kotlin as the language to develop Android apps. Since then along with Java Kotlin has been used in Android development. In fact, you need to write fewer lines of code […]
Interfaces in Java provide us a way to declare the functionality that can be implemented by different classes in their own way. In general, an interface represents a contract. Basically, it is a contract between different groups of people in the software industry where the groups want to agree on how the software should behave. Therefore, the interface contains information regarding what […]
In this article, I will explain Creating Arrays in Java. To begin with, let us first understand what an array is. Basically, an array represents a collection of elements. So, an array can contain multiple values of the same data type. Additionally, all elements in an array occupy the contiguous locations in memory. Further, all the elements of an array […]
This article demonstrates several Examples of For-each Loop in Java. In fact, the use of for-each loop makes traversing the elements of a collection much simplified. The following code shows a simple example of displaying the elements of an array using the for-each loop. As can be seen, there is no loop control variable to track the array index. In […]
This article demonstrates Method-Overloading Using Java. Earlier, I have explained how to create user-defined methods. Accordingly, a class can have user-defined methods which are all uniquely named. In other words, in a particular class, each method has a unique name. However, this rule has an exception. In other words, a class may allow two or more methods to have the same name […]
