Answer 3

In Android, programming is done in two languages JAVA or Kotlin and XML(Extension Markup Language). The XML file deals with the design, presentation, layouts, blueprint, etc (as a front-end) while the JAVA or KOTLIN deals with working of buttons, variables, storing, etc (as a back-end). And the biggest confusion for an Android beginner is which language to choose between Java and Kotlin? So let me try to overcome the confusion first.

Java or Kotlin?

Java is the official language for Android App Development and consequently, it is the most used language as well. Many of the apps in the Play Store are built with Java and it is also the most supported language by Google.

Kotlin is a cross-platform programming language that may be used as an alternative to Java for Android App Development. It has also been introduced as a secondary “official” Java language in 2017. The only sizable difference is that Kotlin removes the superfluous features of Java such as null pointer exceptions. It also removes the necessity of ending every line with a semicolon. In short, Kotlin is much simpler for beginners to try as compared to Java and it can also be used as an “entry point” for Android App Development.
