How to find a string in a string in Golang?

Hi Friends 👋,

Welcome To aGuideHub! ❤️

Today, I’m going to show you how do I find a string in a string in golang, here I’m using the golang Contains() method to check string contains a sub string or not.

The Contains() method returns a boolean value based on whether the sub-string contains a string or not, it expects a string in the first parameter and a sub-string as the second parameter.

Let’s start today’s tutorial How to find a string with in a string in Golang?

Well, I’m going to write a program, where I will use the strings.Contains() method with different parameter examples and then we will see what it is returning.

package main

import (
	"fmt"
	"strings"
)

func main() {
	fmt.Println(strings.Contains("seafood", "foo"))
	fmt.Println(strings.Contains("seafood", "bar"))
	fmt.Println(strings.Contains("seafood", ""))
	fmt.Println(strings.Contains("", ""))
}

When you run the above program you will get the output true, false, true, and true. let’s check the output.
