Java String startsWith in Go With Example Code

Java’s `startsWith` method is a useful tool for checking if a string starts with a certain prefix. However, if you’re working in Go, you might be wondering how to achieve the same functionality. Fortunately, Go provides a simple solution with the `strings.HasPrefix` function.

To use `strings.HasPrefix`, simply pass in the string you want to check as the first argument, and the prefix you want to check for as the second argument. The function will return a boolean value indicating whether or not the string starts with the given prefix.

Here’s an example of how to use `strings.HasPrefix` in Go:

package main


import (

    "fmt"

    "strings"

)
func main() {

    str := "Hello, world!"

    prefix := "Hello"

if strings.HasPrefix(str, prefix) { fmt.Println("String starts with prefix") } else { fmt.Println("String does not start with prefix") } }

In this example, we’re checking if the string “Hello, world!” starts with the prefix “Hello”. Since it does, the program will output “String starts with prefix”.

Overall, `strings.HasPrefix` is a simple and effective way to check if a string starts with a certain prefix in Go.
