JAVA.

Java is an object-oriented language that can be controlled either through a virtual machine or using a browser. This provides convenience in the case of reuse of the developed code and software updates, which happens quite often in the case of a mobile OS. When discussing the production of applications for mobile, most often this implies native products, that is, those that are written for a specific mobile OS. Here, Java programming is important primarily for those who decide to create applications for Android.
