Java Guava | Bytes.hashCode() method with Examples

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

Parameter: This method takes a mandatory parameter value which is a byte 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 Bytes.hashCode() method

import com.google.common.primitives.Bytes;
import java.util.Arrays;

class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Using Guava's Bytes.hashCode()
        // to get hash code for a value
        System.out.println("HashCode value of 10: "
                           + Bytes.hashCode((byte)10));
    }
}

Output:

HashCode value of 10: 10

Example 2:

Java

// Java code to show implementation of
// Guava's Bytes.hashCode() method

import com.google.common.primitives.Bytes;
import java.util.Arrays;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {
        // Using Guava's Bytes.hashCode()
        // to get hash code for a value
        System.out.println("HashCode value of 15: "
                           + Bytes.hashCode((byte)15));
    }
}

Output:

HashCode value of 15: 15
