Byte hashCode() method in Java with examples

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 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 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
