kotlin vs java

                                    // if is an expression, so ternary operation not needed
val loaded = true
val status = if (loaded) "Ready" else "Loading..."
// "Ready

                                     setBackground(Color.cyan);   // sets predefined color cyan to background of frame

                                    kotlin is the fun... Kotlin is the best thing for android developer beginners.

                                    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.

                                    Kotlin is a language built on and entirely backwards-compatible with Java.
While Java is Object-Oriented first, Kotlin supports a blend
of OO and functional paradigms. For further information, refer to
