Byte hashCode() method in Java with examples

Last Updated : 05 Dec, 2018

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
