Java Guava | Booleans.hashCode() method with Examples

Last Updated : 10 May, 2019

Booleans.hashCode() is a method of Booleans class in Guava Library which is used to return a hash code for a boolean 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(boolean value)

Parameter: This method takes a mandatory parameter value which is a boolean 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

// Java code to show implementation of
// Guava's Booleans.hashCode() method
import com.google.common.primitives.Booleans;
import java.util.Arrays;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {
        // Using Booleans.hashCode() method to
        // get the hash code for value
        System.out.println(Booleans.hashCode(true));
    }
}

Output:

Example 2 :

Java

// Java code to show implementation of
// Guava's Booleans.hashCode() method
import com.google.common.primitives.Booleans;
import java.util.Arrays;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {
        // Using Booleans.hashCode() method to
        // get the hash code for value
        System.out.println(Booleans.hashCode(false));
    }
}

Output:
