How to Java String contains in Go

The Java String contains function is a method that is used to check whether a particular sequence of characters is present in a given string or not. It returns a boolean value of true if the specified sequence of characters is found in the string, and false otherwise. The method takes a single argument, which is the sequence of characters to be searched for in the string. It is case-sensitive, meaning that it will only match the exact sequence of characters provided. The contains function is commonly used in string manipulation and searching operations in Java programming. Keep reading below to learn how to Java String contains in Go.

Java String contains in Go With Example Code

Java developers who are transitioning to Go may find themselves wondering how to perform a Java String contains in Go. Fortunately, Go provides a simple solution for this common task.

In Java, the String class provides a contains() method that returns a boolean indicating whether a given substring is present in the string. In Go, the strings package provides a Contains() function that performs the same task.

To use the Contains() function, simply import the strings package and call the function with the string and substring as arguments. The function returns a boolean indicating whether the substring is present in the string.

Here’s an example of how to use the Contains() function in Go:

import "strings"

func main() { str := "Hello, world!" substr := "world" if strings.Contains(str, substr) { fmt.Println("Substring found!") } else { fmt.Println("Substring not found.") } }

In this example, the Contains() function is used to check whether the substring “world” is present in the string “Hello, world!”. The function returns true, so the program outputs “Substring found!”.

Overall, performing a Java String contains in Go is a simple task thanks to the strings package’s Contains() function.

Equivalent of Java String contains in Go

In conclusion, the equivalent function to Java’s String contains() in Go is the strings.Contains() function. This function takes two arguments, the first being the string to search in and the second being the substring to search for. It returns a boolean value indicating whether the substring was found in the string or not. While the syntax and implementation of the function may differ between Java and Go, the functionality remains the same. As a developer, it is important to be familiar with the various programming languages and their functions in order to efficiently and effectively solve problems. By understanding the equivalent functions in different languages, we can easily transition between them and write code that is both concise and effective.
