Byte hashCode() method in Java with examples

Last Updated : 11 Jul, 2025

The

method of

is a built in method in Java which is used to return the hash code of the ByteObject.

The hashCode() returns the same value as intValue().

ByteObject.hashCode()

It return an

value which represents the hashcode of the specified Byte object. Below is the implementation of hashCode() method in Java:

// Java code to demonstrate
// Byte hashCode() method

class GFG {
    public static void main(String[] args)
    {

        String value = "74";

        // wrapping the byte value
        // in the wrapper class Byte
        Byte b = new Byte(value);

        // hashCode of the Byte Object
        int output = b.hashCode();

        // printing the output
        System.out.println("HashCode of "
                           + b + " : " + output);
    }
}

HashCode of 74 : 74

// Java code to demonstrate
// Byte hashCode() method

class GFG {
    public static void main(String[] args)
    {

        String value = "-17";

        // wrapping the byte value
        // in the wrapper class Byte
        Byte b = new Byte(value);

        // hashCode of the Byte Object
        int output = b.hashCode();

        // printing the output
        System.out.println("HashCode of "
                           + b + " : " + output);
    }
}

HashCode of -17 : -17
