Obtain the hash code for a string in Java
The hashCode() method is used to obtain the hash code for a string. This method does not accept any parameters as it is a default method and it returns a hash code value.
A program that demonstrates the hashCode() method in Java is given as follows:
Example
import java.io.*; public class Demo { public static void main(String args[]) { String str = new String("The sky is blue"); System.out.println("The string is: " + str); System.out.println("The Hashcode for the string is: " + str.hashCode()); } }
Output
The string is: The sky is blue The Hashcode for the string is: -729257918
Now let us understand the above program.
The string str is defined. Then the string is printed and its HashCode is also printed using the hashCode() method. A code snippet which demonstrates this is as follows:
String str = new String("The sky is blue"); System.out.println("The string is: " + str); System.out.println("The Hashcode for the string is: " + str.hashCode());
