java vs kotlin code example

Example 1: what is kotlin

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin mainly targets the JVM, but also compiles to JavaScript or native code (via LLVM). Language development costs are borne by JetBrains, while the Kotlin Foundation protects the Kotlin trademark.
On 7 May 2019, Google announced that the Kotlin programming language is now its preferred language for Android app developers. Since the release of Android Studio 3.0 in October 2017, Kotlin has been included as an alternative to the standard Java compiler. The Android Kotlin compiler lets the user choose between targeting Java 6 or Java 8 compatible bytecode.

Example 2: kotlin vs java

chunk of code written in Kotlin is much smaller compared to Java, as it is less verbose and less code means fewer bugs. Kotlin compiles the code to a bytecode which can be executed in the JVM. Thus, all the libraries and frameworks made in Java can be moved and run in a Kotlin project.

Example 3: Kotlin is like java

val age = 42

if (age < 10) {
    println("You're too young to watch this movie")
} else if (age < 13) {
    println("You can watch this movie with a parent")
} else {
    println("You can watch this movie")
}

Example 4: Kotlin is like java

val explicitDouble: Double = 70.0
