Java Guava | Floats.hashCode() method with Examples

  • Last Updated : 29 Jan, 2019

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

Parameter: This method takes a mandatory parameter value which is a float 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 Floats.hashCode() method
  
import com.google.common.primitives.Floats;
import java.util.Arrays;
  
class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Using Floats.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 10.12f: "
                           + Floats.hashCode(10.12f));
    }
}
Output:
HashCode value of 10.12f: 1092742021

Example 2 :




// Java code to show implementation of
// Guava's Floats.hashCode() method
  
import com.google.common.primitives.Floats;
import java.util.Arrays;
  
class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Using Floats.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 20.24f: "
                           + Floats.hashCode(20.24f));
    }
}
Output:
HashCode value of 20.24f: 1101130629
