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.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 {String str =
"Java Examples Code";System.
out.println("Corresponding hash code value returned is: "+ str.hashCode());
}
}
the output is:
Corresponding hash code value returned is: 1275699718
