May you briefly compare Kotlin vs Java?

Câu trả lời

Here is a concise comparison of Kotlin vs Java:

Kotlin is a modern, concise, and type-safe language that runs on the Java Virtual Machine (JVM). It has several advantages over Java:

  • Kotlin code is more concise and expressive, with features like null safety, extension functions, and lambdas[1][2][3]. This can lead to 40% less code compared to Java[1].
  • Kotlin has built-in null safety to avoid NullPointerExceptions, a common source of bugs in Java[2][3].
  • Kotlin is interoperable with Java, allowing you to call Kotlin from Java and vice versa in the same project[1][2].
  • Kotlin has better support for functional programming with features like lambdas and extension functions[1][3].
  • Kotlin has a growing community and is increasingly popular for Android development, with Google supporting it as an official language for Android apps[2][3]...
