Kotlin transmits variable length parameters to Java Variable Parameter instance code, kotlinjava

This article mainly studies how Kotlin transfers variable length parameters to Java variable parameters. The specific implementation code is as follows.

Defines Java Variable Parameter Methods

Package com. tcl. john. studymvvm. utils;/*** call Java method tool class * Created by ZhangJun on. */public class CallJavaUtils {public static int addNumbers (String name, int... args) {int result = 0; for (int I = 0; I <args. length; I ++) {result + = args [I];} return result ;}}

Kotlin passes the variable length parameter and calls the above Java method

// Test whether Kotlin passes the variable length parameter to the Java Variable Parameter Method var numbers: IntArray = intArrayOf (1, 2, 3, 4, 5) CallJavaUtils. addNumbers ("add", * numbers)

Summary

The above is all about passing a variable length parameter to the Java Variable Parameter instance code in Kotlin. I hope it will be helpful to you.
