Kotlin vs Java: Which is Better for Android App Development?

1. Easy to Use

Kotlin is very easy to use and learn. Kotlin comes with a good collection of tools and IDE’s along with tutorials, making it easier for mobile application development. If you hire android app developers from Kotlin for developing applications, they will deliver your projects in less time. Kotlin allows kaolin which is an interactive app for 3d learning for inspecting 3d data sets for Android app development. Even beginner programmers can easily catch up with Kotlin.

2. Cross-platform Development

Kotlin can run on multiple platforms. They can cross-compile. Therefore, Kotlin has the feature of cross-platform development beyond mobile. Kotlin applications can work on various operating systems like macOS, Windows, Android, iOS, and others. Kotlin can be used to share common code between Android and iOS like connectivity, busy logic, and many more. It is considered pragmatic.

3. Data Classes

Several classes under huge projects are meant to hold data. These classes have little to no functionality. Still, a developer needs to write a lot of code in Java. A developer is needed to define a constructor, several fields for storing the data functions for each field and equals hashcode and toString functions.
Kotlin has a simple way of creating these classes. Only the data keyword is needed to be included by the developer in the class definition, and the compiler will take care of the entire task.

4. High-order Functions and Lambdas

High-order functions in Java are made possible through Callables and Lambdas. In Kotlin, they are pre-built. A higher function order takes functions as parameters or returns a function. Lambdas are anonymous methods that are important. At the same time, these are the few things worth knowing when it comes to Kotlin.

5. Null Safety

Java has let its developers with the feature if the null assigning value to any variable. In case they try to use an object reference that has a null value, there comes the NullPointer Exception.

6. Coroutines

Until the operation is completed, the calling thread is blocked. Android is single-threaded by default, so an application’s UI gets frozen when the main thread is blocked. In Java, the solution provided is to create a background thread for intensive work. Managing multiple threads leads to a rise in the completion of the program, followed by errors in the code.

7. Inline Functions

Every function in Kotlin and Java is an object. The object captures a closure. Both the objects and classes call for the allocation of memory. Runtime overhead is introduced with virtual calls along with classes and functions. To avoid additional overhead, the lambda expressions can be inlined in Kotlin. One of the examples is the lock function.

8. No Checked Exceptions

The checked exception feature in Java might be problematic sometimes. Checked exceptions occur when the compiler forces the caller of the function to catch an exception. Checked exceptions are unnecessary and cause empty catch blocks. Non-existent checked exceptions are annoying for developers.
Kotlin features checked expressions that might cause problems. However, Kotlin removes the checked exceptions completely. This minimizes the verbosity and improves type safety.

9. Interoperability

Collins’s core feature is interoperability. The project intends to utilize the existing knowledge and expertise to make every library available to Kotlin programmers. Simply writing modules in Kotlin can work flawlessly within existing Java code. By removing the byte code, a Kotlin compiler allows two languages to work together in the same project.

10. Brevity

Most of the developers praise Kotlin for its conciseness. However, Java doesn’t have this feature. Another important thing is that readability should always take priority over concision. Kotlin simplifies the developer’s job and reduces the risk of error but Kotlin does not practice concision. Boilerplate is a problem to read. This leads to more bugs and more waste of time trying to identify them.

11. App Crash

Kotlin uses fewer lines of code as compared to Java which uses bigger coding lines. Less coding reduces overall development time. Less coding also supports the maintenance needs.

12. Scalability

Java languages are not scalable. They are like C++. They get bloated and affect the performance. This might create a disturbance. On the other hand, Kotlin has a strong focus on scalability and its design.
