It is an open source programming language that combines object-oriented programming features.
The features like Range Expression, Extension Function, Companion Object, Smart casts, Data classes are considered to be surplus of the Kotlin Language.
Kotlin supports only two types of programming, and they are:
Kotlin eases the coding process as it is simpler than Java and has many features required, that is not provided by Java yet like Extension functions, Null Safety, range expressions etc.
In Kotlin, we code approximately 40% less number of code lines as compared with Java.
The Kotlin program once compiled, can run on standard JVM like other programming codes.
And, like many other programming languages main() function is the entry point of the Kotlin.
There are two types of constructors in Kotlin:
JVM, which stands for Java Virtual Machine is a feature of Kotlin.This feature compiles a Kotlin code into a native code, which can be done without JVM too.
There are three Structural expressions in Kotlin.
In programming, we use classes to hold data and these classes are called as data classes.
An object can be initialized in the data class and to access the individual parameters of these data classes, we use component functions.
The modifier in Kotlin provides the developer to customize the declarations as per the requirements.
Kotlin provides four modifiers.
Yes, we can migrate the code from Java to Kotlin.
This can be done using JetBrains IDEA, which facilitates the conversion of Java code to Kotlin code.
Val: Val, which is the short form of value, is a constant and it cannot be changed once assigned.
Var: Var, which is the short form of variable, is a storage location that accepts the reassignment of values that have the same data types.
In Kotlin, the Null safety is used to eliminate the risk of countering the Null Pointer exception in real time.
Data types of a constant or variable decide what type of variable it is and how much space is required to store it.
The basic data types in Kotlin are:
Strings are a collection of characters together.
Kotlin features two types of strings, and they are:
In Kotlin String, templates can be evaluated.
This evaluation of string templates is called as the string template interpolation.
