What is Kotlin?
Kotlin is a statically typed programming language based on the Java Virtual Machine (JVM), which can be called and mixed with Java code. Influenced by many modern programming languages such as Swift, Scala, Groovy, and C#, Kotlin is considered a powerful, intuitive, safe and reliable programming language. Kotlin has many features including null safety, extension functions, functional programming, type inference, etc.
Kotlin's null safety features can reduce program crashes caused by null pointer exceptions; extension functions allow developers to easily add new functions without modifying classes; functional programming features allow Kotlin to easily handle asynchronous tasks , streaming data, etc.; the type inference feature can reduce code redundancy, making the code more streamlined and easy to maintain. Kotlin has become one of the most popular third-party programming languages in the field of Android development, and is one of the preferred languages for developing Android applications, just like Java.
Is it necessary to learn Kotlin?
The answer to the question of whether learning Kotlin is necessary depends on your development needs and goals. If you are an Android application programmer and want to improve your development efficiency and code quality, it is necessary to learn Kotlin. Many Android application programmers have started using Kotlin to write new applications and update their existing applications, because Kotlin has some key advantages that can make your development more efficient and enjoyable:
- Concise: Kotlin code is more concise than Java, you can complete the same function with less code, reduce the time to read and write code, and reduce the risk of errors.
- Security: Compared with Java, Kotlin is safer for Null Pointer exceptions. When writing Kotlin code, the compiler will automatically check for null values and prompt developers to fix them.
- Interoperability with Java: Since the underlying technology is the Java Virtual Machine (JVM) environment, Kotlin can call and mix with Java code, and it is compatible with existing Java libraries and toolsets.
- Powerful functions: Kotlin supports modern coding paradigms such as extension functions, data classes, functional programming, and coroutines. These capabilities allow developers to write more beautiful and streamlined code.
What Kotlin learns, the growth path is one step faster
No matter what you study, you need to sort out your thinking clearly in order to be fast, accurate, and ruthless. For fast and efficient learning and growth, the learning steps in the "Kotlin Manual" are recommended as follows:
1. Basic grammar
2. Basic type
3. Classes and Objects
4. Functions and lambda expressions
5. Other key knowledge
6. Tools
7、FAQ
Learning the Kotlin language requires a certain programming foundation. Here are some steps to learn Kotlin:
- Learning basic grammar: Learning the basic grammar of Kotlin is an important step in laying a good foundation, including variable definition, control flow statement, function, class, preliminary Lambda, etc.
- Complete some practical exercises: Complete some practical exercises by learning the grammar of Kotlin, such as using Kotlin to write simple console applications, web applications, etc., combined with practical exercises to continuously deepen the understanding of Kotlin.
- Master special features: Kotlin has many unique language features, such as null safety, extension functions, data types, etc. Through practice and document learning, gradually master these features.

The Kotlin language has developed rapidly since its release and has been widely used in the Android development field. Kotlin has many features, such as null safety, extension functions, functional programming, etc. These features can greatly improve development efficiency and code quality. In addition, Kotlin's concise and easy-to-understand syntax and good interoperability with Java have also made it easier for many Java developers to switch to Kotlin.
In addition to its application in the field of Android development, Kotlin is also widely used in back-end development, web development, data analysis, machine learning and other fields. The use of Kotlin in these fields is increasing, especially in Java frameworks such as Spring, and Kotlin is also becoming more and more popular.
Kotlin's developer, JetBrains, continues to promote the development of Kotlin, including developing new language features, optimizing compilers, and extending Kotlin's applications between different platforms. These efforts have also made Kotlin gradually become a popular programming language.
In conclusion, the future of Kotlin is promising, it is becoming a powerful and widely used programming language, which will continue to be more widely used and developed in different fields.
