Doubles.hashCode() is a method of Doubles Class in Guava Library which is used to return a hash code for a double value. The hashCode is an unique integer value that is calculated by the compiler for an object. It remain the same if the object value does not changes.
Syntax:
public static int hashCode(double value)
Parameter: This method takes a mandatory parameter value which is a double value for which the hashCode is to be found.
Return Value: This method returns an integer value which is the hash code for the specified value.
Below programs illustrate the use of the above method:
Example 1:
// Java code to show implementation of // Guava's Doubles.hashCode() method import com.google.common.primitives.Doubles; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Using Doubles.hashCode() method to // get the hash code for value System.out.println( "HashCode value of 10.12: " + Doubles.hashCode( 10.12 )); } } |
HashCode value of 10.12: -470599859
Example 2:
// Java code to show implementation of // Guava's Doubles.hashCode() method import com.google.common.primitives.Doubles; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Using Doubles.hashCode() method to // get the hash code for value System.out.println( "HashCode value of 20.45: " + Doubles.hashCode( 20.45 )); } } |
HashCode value of 20.45: 1929854976
