Java Guava | Ints.hashCode() method with Examples
  • Last Updated : 29 Jan, 2019

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

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

Example 2:




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