The original understanding of the technical understanding of the Kotlin Stdlib Common framework in Java Library

KOTLIN Stdlib Common is a class library supporting Kotlin language, which aims to provide cross -platform functions and API support.Its technical principle is to integrate the class library of Java and Kotlin through sharing code libraries. In the Java library integration, the technical principles of using Kotlin Stdlib Common are mainly in the following aspects: 1. KOTLIN Multi -Platform Project: Kotlin supports multiple platform projects, allowing to write code applicable to multiple platforms in a single project.By using the function of Kotlin multi -platform projects, the Kotlin code can be used for different platforms, such as JVM, JavaScript and Native.This allows you can use the Kotlin code to call the Java class library when integrating the Java class library. 2. Kotlin language interoperability: Kotlin is designed as a language that is highly interactive with Java language.Therefore, the Kotlin code can seamlessly interact with the Java code.This means that the Kotlin code can directly use the class and methods in the Java class library. The following is an example of JAVA library integration using Kotlin Stdlib Common: Suppose we have a Java class library to calculate the sum of an integer array.There is a Java class called `Sumcalculator`, which is a static method. The static method` Calculatersum () `can be used to calculate the sum of the array. Now, we want to use this Java class library in the Kotlin code.We can follow the steps below for integration: 1. Import java class library: At the top of the Kotlin code, use the `Import` keyword to import the class or method of the Java library.For example: kotlin import com.example.SumCalculator 2. Call the Java class library method: By using the imported Java class or method, we can directly call this method in the Kotlin code.For example: kotlin val numbers = intArrayOf(1, 2, 3, 4, 5) val sum = SumCalculator.calculateSum(numbers) println("Sum: $sum") In the above example, we introduced the `SumcalCulator` class, and then calculated the sum of the integer array by calling its` Calculatesum () `method. Through the above steps, we successfully integrate the Java library into the KOTLIN code, and we can use the function of the Java library directly in the Kotlin code. To sum up, Kotlin Stdlib Common has achieved the integration of Java libraries through the interoperability of shared code libraries and Kotlin language.This provides developers with the convenience of using the Java library and can directly call the Java library in the Kotlin project.
