¿Se puede llamar a una función de Kotlin en Java?

Can a Kotlin function be called in Java?

In fact, Kotlin code is fully compatible with Java code. Therefore, you can be able to use both the Java and Kotlin languages in a single project due to Interoperability. You can call Kotlin functions in Java as well as Java methods and variables in Kotlin code.

The Android Button syntax is the result of SAM conversion of Java code. setOnClickListener ends up more concise than onClickListener = only because with the latter, the listener is a Java interface you have to name rather than a Kotlin function. It’s really verbose to write: button.onClickListener = OnClickListener { //…

Kotlin is new to the Android space and is picking up momentum and with this in mind, I recently asked myself “I wonder how I am going to reverse Android applications built with Kotlin?”.

Kotlin also provides an ability to iterate from the greater number down to the smaller number using downTo. The iteration step size can also be changed using step. The code above with result in 97531. It’s a problem number 1119 on Leetcode. Given a string S, remove the vowels ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’ from it, and return the new string.

It not only provides a copy of the original object, leaving its state intact, but also allows setting new values to some of its properties at copy-time: Kotlin supports named parameters, known from other languages, such as Python and Scala.

This private field exists in the java class generated from the kotlin file. These properties can be accessed using the object of the class, in the same way as done in Java. However, if the property name begins with is, then the get keyword is skipped in the name of the getter function.

Java’s primitive types are mapped to corresponding Kotlin types (keeping platform types in mind): Java type Kotlin type byte kotlin.Byte short kotlin.Short int kotlin.Int long kotlin.Long

The image above shows that the MainActivity.smali generated for the Kotlin and Java applications differ significantly. The Kotlin MainActivity.smali contains 173 lines of Smali and the Java MainActivity.smali contains 71 lines of Smali.

The image above shows the contents of the exploded obfuscated Kotlin APK which shows us that the size of classes.dex is 826KB, the exact same size of the obfuscated Java application! Another interesting observation is that most of the files in the APK are the same size, the only differences are the folders “META-INF” and “kotlin”.
