If you start programming in Android, often the language we use Java. Moreover, Java is used worldwide. Now Kotlin arrives, which brings great improvement. We decide to create this Java blog against Kotlin. Which language is best?
To understand the attitude of Kotlin against Java, the main thing is that we decided to discuss a little of each language. We'll start with Java, and you'll learn about its interesting places, weaknesses, and what we can do with that language.
Next, will we discuss Kotlin with the purpose of this language, favorable circumstances, services, and what can we do? Finally, it will incredibly understand the critical Java contrasts against Kotlin.
Java introduction
The java-object-ordered programming language, which was presented by Sun Microsystems. He appeared 23 years ago, and with other famous languages like Scala and Groovy, he remained in significant languages in improving Android apps.
Since its inception, Java's application promotion for Android is widely used in structuring server applications, Android applications, Web applications, inserted frameworks, and sites. A more significant part of Java components is available in open source. The glory of Java-the most significant in promoting programs related to money.
Kotlin Introduction
Kotlin is a universally useful programming language that includes Java, Android, JavaScript, and Native virtual machines. JetBrains creates it as an open-source stage, according to Apache 2.0.
If you request "Why to use Kotlin " for the Android Studio programming language; This is because the engineer can send Kotlina as an objective programming and useful programming. Kotlin uses compiler LLVM's innovation to collect Kotlin code in binary files for CPU designs and working frames such as iOS, Windows, Linux, and Mac.
Perhaps the best thing in this language is that it combines both object-located and useful characteristics of programming.
Java Vs Kotlin
1 Market Circumstance
The impact of Java on the modern world is enormous. Since July 2019, Java has continued its primary position, comparable to July 2018. Kotlin, but still youthful language, entered the 50 Best rankings by putting the number 43.
The Google collect I/O 2017 was a disexploded move of Kotlina at the position of programming languages "top-line " To improve Android applications.
He joined the old Big Java and C++. Declaration has strengthened interest in Kotlina, causing a stunning development of its popularity.
2 Progress
First, Kotlin was designed in such a way that it could without much stretch to interact with Java. Therefore, designers can interpret the Java codes in Kotlin and vice versa, that also without the need to change the efficiency.
Kotlin is a new language, offers some additional characteristics that make Kotlin the preferred choice of Java. The client cannot share between the two since both programming languages codes are compiled into a byte JVM code.
3 Smart Casts
In Java we have to check the type of factors and define them with our activity.
In Kotlin, smart caste will work with these cheques casting with the help of keywords "there-checks," which check on consistent quality and perform hinted casting.
4 Null Safety
In Java, NullPointerExceptions raises huge dissatisfaction engineers. It allows customers to take invalid to any factor by moving to a link to an object that is invalid and builds an invalid specific case with which the customer should be engaged.
In Kotlini, by default, a wide range of factors is disabled (for example, we cannot distinguish invalid quality factors/objects). If we try to assign or return invalid classes, the code of Kotlina will deteriorate during the agreed time. If we really need a variable to have an invalid cost, we may proclaim it as follows.
5 Type Inference
In Java, we need to state the type of each factor in the announcement clearly.
In Kotlin, we do not need to specify the type of every factor that is uniquely dependent on the task with which it will deal. If we need to state it directly, we can do it.
6 Useful Programming
Java doesn't have practical programming support until Java 8; however, when you create Android apps, it supports a core subset of Java 8 features.
Kotlin is a mixture of procedural and useful programming language that includes many useful strategies, such as lambda, overburdening administrator, higher query capabilities, apathetic evaluation, and so on.
7 Expansion Functions
In Java, if we need to expand the use of an existing class, we need to take a different class and get a parent class. Therefore, extension capabilities are not available in Java.
Kotlin gives designers the opportunity to expand the current class with new usefulness. We can expand the work by adding a prefix of the class name, to name a new capacity.
8 No Checked Exceptions
In Java, we tested special case support that forces designers to announce and receive an exception that finally asks for strong bug handling.
In Kotin, we didn't check any special cases. Thus, designers do not need to announce or receive special cases that have their advantages and limitations.
9 Information Classes
Suppose we need a class in Java that should contain information, but nothing more. To do this, we need to characterize the designers, the factors for storing information, the methods of obtaining and installing, the features of hashcode (), toString (), and equivalence ().
In Kotlin, if we require classes that should contain information. We can declare a class with the keywords "information" in determining the class, then the compiler will do most of the work. For example, we are creating constructors, methods of receiving, installation for different fields.
Conclusion
Finally, an overview of the difference between Java and Kotlin. Based on this, you'll have a better understanding of Java and Kotlin after reading this Java vs. Kotlin article. In my opinion, we can continue to promote Kotlin applications for Android, not limited to the time of accumulation, even though Java has a few favorable circumstances compared to Kotlin.
