If you are interested in developing an android application and you are in a dilemma about which language to choose, then this article is for you. In this article, we will help you to decide which language to pick i.e., Java or Kotlin.
So, let's get started.
Java is an object-oriented programming language, developed by Sun Microsystems(now the product of Oracle). It is widely used as the server-side language for most backend development projects. It is a platform-independent, easy-to-learn programming language that is designed for building object-oriented programing language. Also, it is a multithreaded programming language with automatic memory management. It is considered as one of the fast, secure, and reliable programming languages that are preferred by most of the organization for project building.
public class Main
{
public void Name(String fName, String lName) {
String Name = fName + " " + lName;
System.out.println("The student's name is : " + Name);
}
public void Age() {
int age = 18;
System.out.println("The student's age is : " + age);
}
public void Address() {
String address ="Mumbai";
System.out.println("The student's address is : " + address);
}
public static void main(String args[]) {
Main m = new Main();
m.Name("John","Stewart");
m.Age();
m.Address();
}
}
The student's name is: John Stewart
The student's age is: 18
The student's address is: Mumbai
Kotlin is a newly created programming language developed by Google. It is inspired by Java but is an improved version of it with many additional features. It is widely used for Android App Development. It is an open-source statically typed programming language that targets the JVM, Android, JavaScript, and Native. It is faster to compile and easy to learn. It is mainly focused on interoperability, safety, clarity, and tooling support. It is supported by all the major IDEs including AndroidStudio, Eclipse, and NetBeans.
class Main {
fun Name(fName: String, lName:String) {
var Name = "$fName $lName"
println("The student's name is : $Name")
}
}
fun Age() {
var age : Int
age = 19
println("The student's age is: $age")
}
fun Address(){
var address : String
address="Delhi"
println("The student's address is: $address")
}
fun main(args: Array<String>) {
Main().Name("Mike","Stewart")
Age()
Address()
}
The student's name is: Mike Stewart
The student's age is: 19
The student's address is: Delhi
These are some of the Java issues that are addressed by Kotlin:
