Here are a few features of the Kotlin that will make you sure of the progress path of the programming language.
Trimmed Coding:
Kotlin is an OOPs-based programming language where code line can be trimmed up to 40 % that which makes Kotlin an ideal choice for software or web development.
Open-Source:
Kotlin for Android utilizes JVM and combines the features of OOPs and functional-oriented programming.
Fast Compilation:
it is easy to compile the code when working with Kotlin that results in better performance for android development, and it will also explain which type of data function can be used in the entire code.
Extension Functions:
Kotlin can support a variety of extension functions without making any changes to the code. it helps in making existing code more appealing and magnificent for developers.
For Example:
Fun String.removeFirstLastChar():
String = this.substring(1, this.length -1)
This code will assist in trimming down the first and the last character of the string, we can apply it as:
Val string1 = "Today is cloudy."
Val string2 = string1.removeFirstLastChar()
Null Safety:
In Kotlin, the system distinguishes between null references and not null references as shown in below Kotlin example.
For example, a String variable cannot hold null:
Var string1: String = "Today is Sunday"
String1 = null // compilation error
To permit null, we can adjoin the nullable variable :
Var string2: String? = "Today is Sunday"
String2 = null
print(string2)
Interoperable:
Kotlin code can be used by Java, and Java codes can be used with Kotlin. So, if you have knowledge about OOPS programming, it is easy to switch to Kotlin’s development. Also, if there are some applications written in Java, then they can be used with Kotlin’s environment.
Robust Tools:
Like Java, Kotlin code can also be written using IDE or using the command-line interface. It is easy to work with IDE, and syntax errors are also reduced dramatically. At the same time, when you are working with a command-line interface, code has to be compiled first.
Smart Cast:
Smart casting basically helps to cut down the application costs and improves its speed or performance. It works on managing the efficiency of code using type casting or immutable values.
For example, if the string is identified, then it’s length and count and can be found with the help of Smart Cast function:
Val string1: Any = "Today is Monday"
when(string1)
{
is String -> string1.length
Is Int -> string1.inc()
}
Low Cost of Adoption:
Kotlin is preferred by enterprises because of its lost cost of adoption. Most importantly, it is easy to learn by developers, especially having a programming background.
