Byte hashCode() method in Java with examples (original) (raw)

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
