2) Котлин против Явы

• Используя платформу Kotlin Multiplatform, вы можете извлечь одну общую кодовую базу, которая будет нацелена на все из них одновременно
• Kotlin offers built-in null safety support, which is a lifesaver, especially on Android, which is full of old Java-style APIs.
• It’s more concise and expressive than Java, which means there is less room for error.
• Offers user-friendly and understandable coding norms
• Divides large apps into smaller layers.
• Uses lots of function types and specialized language structures like lambda expressions.
• Helps developers to create extension functions
• Offers a very simple and almost automated way of creating data classes
• Kotlin is a statically-typed language, so it is very easy to read and write.
• This language allows the exchange and use of information from Java in various ways.
• It’ll take less time to write new code in Kotlin.
• It’s quite easier to deploy kotlin code and to maintain it at scale.

Here, are pros/benefits of Java

• Checked exceptions that improve error detecting and solving
• Detailed documentation is available.
• A large pool of skilled developers available
• A huge array of 3rd party libraries
• It allows you to form standard programs and reusable code.
• It is a multi-threaded environment that allows you to perform many tasks simultaneously in a program.
• Excellent performance
• Easy to navigate libraries

Here, are cons/drawback of using Kotlin:

• Small community of developers, so it lacks learning materials and professional assistance.
• Java doesn’t offer a function of checked exceptions that may lead to errors.
• Slower compilation speed than Java
• Kotlin, being a highly declarative language, sometimes it helps you to generate great amounts of boilerplate in corresponding JVM bytecode

Here, are cons/disadvantages of Java:

• Not very suitable for Android API design because of a number of limitations
• Demands a lot of manual work which increases the number of potential errors
• JIT compiler makes the program comparatively slow.
• Java has high memory and processing requirements.
• It does not provide support for low-level programming constructs like pointers.
• You don’t have any control over garbage collection as Java does not offer functions like delete(), free().

• When considering all the pitfalls of Java, especially the problem with NullPointerExceptions, Kotlin seems to be the better one among the two.
• Although Java is still an essential language for every android app development as the Android OS itself is based on the same.
• If you are looking to future proof your android app development services, then you should hire Kotlin developers for the same.
