Writer of sensational headlines?
It may seem like a party in the title, but I know, otherwise, you may not see this article.
Regarding Kotlin related records, if you are interested in viewing my github, its over 10w words (where 8w is the code, haha). .
Why learn?
Without sacrificing performance or security, many Kotlin features make the code more concise and understandable than Java.
Kotlin is compiled to bytecode, so its performance is as good as Java. It has the same compile-time checks as Java (and more, such as built-in nullability checks). Most importantly, Kotlin's language functions and standard library functions can achieve concise and effective code.
Concise, because this is a key factor in improving programmer productivity.
In summary, uphold the love of Kotlin, and hope that more friends can get started with Kotlin better and painlessly. The compressed package in the picture of "Kotlin from Zero to Whole Study Notes" collected and compiled is a large number of actual Kotlin cases. , Share it with everyone for free.

Chapter 1 Introduction to Kotlin
- Kotlin overview
- Kotlin and Java comparison
- Using Android Studio skillfully
- Know the basic types of Kotlin
- Walk into Kotlin's array
- Walk into the Kotlin collection
- Collection problem
- Complete code
- Basic grammar
Kotlin is a statically typed programming language that runs on the Java virtual machine. It is mainly a programming language developed by JetBrains development team. Although Kotlin is not compatible with Java syntax, Kotlin is designed to work with Java code and reuse existing Java reference method libraries such as the Java Collection Framework. It is easy to replace or use with Java in Android projects.
Chapter 2 Kotlin Practical Guide to Avoiding Pitfalls
- Method input parameters are constant and cannot be modified
- No Companion, INSTANCE?
- Java overloading, how to transition in Kotlin cleverly?
- Empty posture in Kotlin
- Kotlin overwrites the methods in the Java parent class
- Kotlin is "cruel", even TODO is not letting go!
- pit in is, as`
- Understanding of Property in Kotlin
- also keyword
- takeIf keyword
- takeIf keyword
- Singleton mode
"If you want to do well, you must first sharpen your tools." Learning the above knowledge points will enable you to do more with less in the next practical study.
