Java vs Kotlin — Which is the Best for Android App Development?
Android application development has become a popular method to expand your business, but the main factor deciding its success or failure is the programming language used. Java is the ideal choice for many people since it is readily accessible. However, Kotlin’s introduction undermined Java’s confidence among developers. Google had little benefits, according to numerous sources, sticking with Java for Android. Switching to Kotlin seemed the best line of action. Given this, let’s analyze the key aspects
Java: What is it?
In the mid-’90s, Java was initially chosen as the primary development tool for Sun Microsystems. It is an object-oriented programming language credited to popularize objects to represent data and other programming components. Its debut extensively replaced procedural programming.
Executing Java programs in the browser is not advised since this will also need Java Applets installations. Since these applets are integrated as plugins, application management may be complex. Back-end development is a more suitable development job that Java can perform.
Kotlin: What Is It?
IDE Jet Brains developed a new programming language called Kotlin to handle sophisticated capabilities not managed by Java. While Kotlin has existed since at least 2011, it was not published until 2016. Compared to Java, Kotlin is an open-source language with substantial security and development advantages.
Kotlin is a static programming language, and Google I/O announced that Kotlin is now one of the officially approved Android application development languages. Even if you want Kotlin to use pre-existing Java stacks, the language allows this. All that’s needed to convert from Java to Kotlin is plugin installation.
What Java offers That Kotlin lacks
Java’s verified exceptions remain a highly desired feature for developers who want to write robust code with error recovery. Kotlin eliminates them to improve code readability, although it is still widely used by many developers.
The primitive types char, double, float, and byte are among the eight that exist only to store pure, simple values of a certain kind. They include a set of predefined actions and are not created from a class or struct in Java.
While Kotlin does not support static members, Java does. Java generates a single instance of the static member that is shared across all class instances. The keyword static indicates that the member with which the keyword was used is a type rather than an instance.
Wildcard types may be used to specify the type of a field, parameter, or local variable, among other things. While Kotlin does not provide wildcard types, Java enables developers to expand functionality via this type of system.

What Kotlin Offers That Java Lacks
Kotlin has emerged as the following Android language, providing developers with a slew of new features.
The Kotlin programming language provides first-class functions that may be placed in data structures and variables, allowing functions to be handled in the same manner that non-function values can be manipulated.
Kotlin supports a wide variety of function types and specific language features such as Lambda expressions as a statically typed language.
Kotlin’s extension functions enable the import of a reference to a View into an activity file, enabling the view to be used as if it were an integral component of the activity. In Kotlin, creating an extension function is as simple as prefixing the name of the class that has to be extended with the name of the newly formed function.
One of the most perplexing issues that Java developers encounter is NullPointerExceptions. Kotlin for Android developers resolves this vexing issue by defaulting to non-nullable types.
Unlike Java, Kotlin enables developers to automatically manage redundant casts without verifying type or cast inside a statement. As long as the cast is previously verified using the “is operator,” the Kotlin compiler’s smart casts keep track of the conditions inside the “if expression.”
String templates in Kotlin enable developers to quickly give dynamic values to strings and print statements in Kotlin.
In Kotlin, primary conductors are used to initializing classes. It may be defined at the class header level, allowing for automated variable initialization.
Kotlin’s advantages to Android developers are apparent, and it is undoubtedly the development future. Many companies declared Kotlin their official Android programming language. Kotlin’s future as the following android language is undoubtedly bright.
The probability is that you already have Java-friendly team members. Switching the whole team to Kotlin at once may jarring. Therefore, making a move gradually, one person at a time is essential.
Kotlin is the next official language and is expected to acquire broad usage in the future owing to its modern nature, so learning it and starting programming now is a wise decision. However, Java will remain a long-term popular programming language and is unlikely to be entirely supplanted. Therefore, take your time and gradually change.
