Multiple Variable Return in Function

A function can return any number of results in Golang. Consider the following program as an example.

package main

import "fmt"

func swap(x string, y int) (int, string) {
	return y, x
}

func main() {
	a, b := swap("Hello", 1)
	fmt.Println(a, b)
}

Output: 1 Hello

In the above program you are passing one string and one int from main function to swap() function. And swap function will return two different datatype’s variable at a time. This is so amazing. Even JAVA can not do it that simple. If you want to return multiple values in JAVA, then you have to encapsulate them into a class and then return an object of that class.
