Kotlin brings forward goodness of modern languages inside android app development without any restrictions. Kotlin is fully compatible with java development kit 6 (JDK 6). This means applications built with Kotlin can run on older Android devices and there will be no such compatible issues with build system of android.
Kotlin Programming Language:
Kotlin application constructed with bytecode structure which makes it as fast as a java application. Due to the support of inline functionalities in codes, it runs faster than Java. All existing android libraries of Java do have interpolation advantage of Kotlin so running these with java file becomes easier.
Kotlin has very compact application library and this speeds up further when the application runs in real time and the application file size is lesser. Kotlin supports incremental compression. Which means it creates the incremental compilation and there is no overhead of files remains when final compression begins.
Why many successful companies use Kotlin as their major language for their web and database programming:
Incremental builds are faster than Java compiler. Many successful companies use Kotlin as their major language. Pinterest has successfully adopted Kotlin as their major application. It is an image ready website and it is used by millions. Presence of Kotlin apps makes this website faster. It provides the great improvement of the site’s quality and speed.
Programmers find that due to the presence of Kotlin as the main source of the code. Programmer finds that there are absolutely 30 percentages in the decrease of codes and 10 percentages in a decrease of method counts. There is some Kotlin extension which makes normal and repetitive codes into synthetic compiler generator properties. Kotlin has some built-in libraries which replace Android APIs (application processing interfaces) and replace the layouts of.xml codes into Kotlin codes.
How to use Kotlin:
You can easily convert third-party frameworks such as JQuert and React to application processing interfaces with Kotlin:
Third party libraries and frameworks are JQuery and React. You can easily convert its application processing interfaces (APIs) into typed definition repository easily with available tools. JetBrains developed and maintained many React community apps add its ‘Create React Kotlin App’ helps you build React app without build configuration.
Kotlin/Native is a framework used for compilation of native binaries for development of code which can run without any virtual manager (VM). There is some operating system such as iOS from Apple which wants embedded targets for apps instead of virtual managers, the presence of Kotlin/Native code is sufficient for code compilation. It creates a self-contained program which can run on any environment without the need for virtual machines.
Kotlin has the self-contained compiler that makes its footprint smaller:
Due to its self-restrained compiler, the standalone self-contained container remains in smaller sizes for platforms that are platform and operating system dependent. Due to its interop libraries, and work in out of the box, the presence and support of native codes are fully possible.
Coroutine execution is part of the library not of code, and this means that it is platform independent. This means that once you create the code then you can use it on any other platforms. The million dollar question is what coroutine execution is. It is a lightweight thread, which can be suspended and resumed one after another. This means it is supported through suspended functions. The work of suspended function is to suspend a coroutine and then start again.
In the case of starting of coroutine functions after suspension, the presence of an anonymous suspending function is there which is better known as suspending lambdas. In this above code, we understand that async… starts the coroutine, and when await … is applied then coroutine is suspended and the operation waiting to be executed at the same time. On a different thread when the coroutine is executed and the operation awaited completes successfully.
The newer version of Kotlin removes restrictions of subclasses of the primary class and in this way, the same data classes can be used in the nested classes of the sealed classes. Kotlin uses a nice form of Java and it fixes a series of Java functions that issues are there with Java and now it is cleared in Kotlin. Kotlin controls null references through the type system.
There are no raw types of Kotlin for Java codes. Arrays in Kotlin are present in the form of invariant. It remains unchanged with reference to functions, quantity or properties when some specific transformations from other functions are applied but still, main functions remain unchanged. Kotlin does not have checked exceptions. It does not use wildcards while using the site variance.
Some shortfalls in Kotlin Language:
There are some shortfalls in Kotlin languages too. Java has checked exceptions, primitive types and not every object is taken into classes, static members, wildcard types and operators. But Kotlin has few powerful objects and classes which java does not have. Kotlin presents users with performance custom control structures through Lambda expressions plus inline functions to provide performance drive custom control structures.
Apart from this Kotlin provides extensions in functions, null-safety, smart casts, string templates, properties, primary constructors, first-class delegation, type inference for variable and property types, singletons, declaration site variance and type projections, range expressions, operator overloading, companion objects, data classes, separate interfaces for read-only and mutable collections and coroutines.
While comparing the properties and conveniences attached with java and Kotlin we do find that Kotlin is modern and provide extreme conveniences for users to write good coding language so that perfection of writing a code with lightweight, platform independent and optimal compiler makes it a charm to use and write apps.
