# Java - String hashCode() Method

## Description:

This method returns a hash code for this string. The hash code for a String object is computed as:

    s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]

Using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. (The hash value of the empty string is zero.)

## Syntax:

Here is the syntax of this method:

    public int hashCode()

## Parameters:

Here is the detail of parameters:

- NA

## Return Value :

- It returns a hash code value for this object.

## Example:

    import java.io.*;

    public class Test{
       public static void main(String args[]){
          String Str = new String("Welcome to Tutorialspoint.com");
          System.out.println("Hashcode for Str :" + Str.hashCode() );
       }
    }

This produces following result:
