Longs.hashCode() is a method of Longs Class in Guava Library which is used to return a hash code for a long 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(long value)

Parameter: This method takes a mandatory parameter value which is a long 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 Longs.hashCode() method
  
import com.google.common.primitives.Longs;
import java.util.Arrays;
  
class GFG {
  
    // Driver's code
    public static void main(String[] args)
    {
        // Using Longs.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 15: "
                           + Longs.hashCode(15));
    }
}
Output:
HashCode value of 15: 15

Example 2:




// Java code to show implementation of
// Guava's Longs.hashCode() method
  
import com.google.common.primitives.Longs;
import java.util.Arrays;
  
class GFG {
  
    // Driver's code
    public static void main(String[] args)
    {
        // Using Longs.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 10: "
                           + Longs.hashCode(10));
    }
}
Output:
HashCode value of 10: 10
