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:
This method 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 www.dineshonjava.com");
System.out.println("Hashcode for Str :" + Str.hashCode() );
}
}
This produces following result:
output:
Hashcode for Str :1186874997
Hashcode for Str :1186874997
