Byte hashCode() method in Java with examples

Last Updated : 11 Jul, 2025
The hashCode() method of Byte class is a built in method in Java which is used to return the hash code of the ByteObject. Note: The hashCode() returns the same value as intValue(). Syntax 
ByteObject.hashCode()
Return Value: It return an int value which represents the hashcode of the specified Byte object. Below is the implementation of hashCode() method in Java: Example 1: 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);
    }
}
Output: 
HashCode of 74 : 74
Example 2: Java 
// 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);
    }
}
Output: 
HashCode of -17 : -17
