What is Kotlin? And what’s Advantages, Disadvantages, Features, and Differences from Java

In recent years, there’s been a programming language that’s rapidly growing in various fields, including Android app development. That language is Kotlin. Developed by JetBrains in 2011, Kotlin is a language that runs on the Java Virtual Machine (JVM). Today, we’ll explore the differences between Kotlin and other programming languages, especially Java, and delve into the advantages, disadvantages, and features of this language.

Kotlin compare Java

Both are languages that run on the JVM, but there are several differences. First, we can see a difference in code length. Kotlin has more concise code compared to Java. It offers various features to reduce unnecessary boilerplate code and allows for even more concise coding with features like lambda expressions and extension functions. Additionally, in Java, null pointer exceptions (NullPointerException) frequently occur, but Kotlin provides features that ensure null safety. In Kotlin, you can append ‘?’ after a variable type to allow null values, and you can use the ‘!!’ operator to forcefully handle such values.
