int hashCode() method in Java returns a hash code for the given string but it can return zero as well if the given string is empty. It can be computed as ..

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

Where..

i -> is a first character

n-> length of the string

^ indicates exponentiation

See the example given below that explains how to get the hashCode for any given string in Java.

a simple hashCode example:

public class StringTrim {

public static void main(String[] args) {

String str = "Java Examples Code";

System.out.println("Corresponding hash code value returned is: "

the output is:

Corresponding hash code value returned is: 1275699718
