Varargs Guide

Varargs

Feature Overview

This feature enables varargs parameters in methods.

Prerequisite

None.

Sweet Apex Example

public class VarargsDemo {
    private static void run(Integer num, String ...args) {
    }

    public static void main() {
        run(10, 'a', 'b');
    }
}

Transpiled Apex

public class VarargsDemo {
    private static void run(Integer num, List args) {
    }
    public static void main() {
        run(10, new List{ 'a', 'b' });
    }
}

Usage

The var-args parameter should be the last parameter in the method and the method should contain at most one var-args parameter. Besides, overloading methods with var-args may cause ambiguity.
