The conversion of Kotlin to Java basically consists of two tasks:

So that we can investigate or see the performance issues.

Integrate some functionalities that can easily be implemented in JAVA.

So that we can remove kotlin from our project.

The first question that arises is why we need to convert Kotlin to Java. When we want to learn that how can we convert Kotlin to Java. This we will learn it in the following tutorial. But if we want to do the vice versa how we can do that. If we want to convert java to kotlin we can easily do it with the help of Android Studio. Interoperability is possible in both the languages because of the JVM (Java Virtual Machine) or in other words we can say that they are compiled to the same bytecode. Kotlin is good for Mobile-cross platform, Native, Data-Science, Server-side, Web-development, Android. public class StudyTonightĭouble d1 = new Double(i) //conversion using the instantiationĭouble d2 = Double.Kotlin is a language that is well known for the interoperability with the java language. Here, the int value is converted into the double by instantiating the class and using valueOf() method. (' The double value is : ' +l) Īlso, we can convert an int value into a Double Object either by instantiating Double class or by using the Double.valueOf() method. Here, the int values are converted into double values implicitly by using the assignment operator. This is because this conversion is an example of Type Promotion(Implicit type conversion) in which a lower data type is automatically converted into a higher data type. In Java, an int value can be converted into a double value by using the simple assignment operator.
