Java vs Kotlin – What To Choose For Android App Development

Kotlin, an open-source project, first appeared in 2011. Time passed and the debut on which language is better for Android App Development started. Java vs Kotlin is yet the most discussed topic among the developers while it is the most confusing topic for non-tech people. We did deep research on various app development programming languages and came up with some true points which needs to be considered before choosing Java or Kotlin.

From Developers Perspective

From unending debut on Java vs Kotlin, some major differences are listed below;

• Checked Exception:  Kotlin needs no checked exceptions and no need to declare any try/catch block. While in Java, use of exception blocks is believed to be done for better error recovery.
• Code Conciseness: Comparing equivalent Java and Kotlin classes, Java requires more code to perform any action than Kotlin.
• Coroutines: When multiple threads are created in Java in background, it uses more memory, while Kotlin allows to create coroutines which are stackless and as a result uses less memory.
• Extending Functions: When there is a need to add new functionality to any class, Kotlin provides extension functions but in Java there is no availability of such functions.
• Null Pointers: Java allows to assign null pointers to any variables for NullPointerExceptions. While there is no NullPointerExceptions in Kotlin as null value can be assigned by putting question mark sign after the type.
• There are many other features like smart casts, static members, support for constructors, ternary operator, wildcard type that adds on to the features of Kotlin.
