Java Byte hashCode() method

The hashCode() method of Java Byte class returns a hash code for this Byte.

Syntax:

public int hashCode() 
public static int hashCode(byte value)

Parameters:

The parameter 'value' represents a value whose hash code is to be determined.

Overrides

The hashCode() method overrides hashCode in class Object.

Return Value

This method returns a hash Code value for this Byte.

Example 1

public class ByteHashCodeMethodExample1 {
        public static void main(String[] args) {
            Byte b1 = new Byte((byte) 0.78);
            //returns the hash code for b1
            int val=b1.hashCode();
            System.out.println("1. Hash Value = " +val);
            Byte b2= 12;
            System.out.println("2. Hash Value = " +b2.hashCode());
            //passing negative byte
            Byte b3 = new Byte((byte) -1);
            System.out.println("3. Hash Value = " +b3.hashCode());
        }
    }

Test it Now

Output:

Hash Value = 0
Hash Value = 12
Hash Value = -1

Example 2

import java.lang.*;
public class ByteHashCodeMethodExample2 {
    public static void main(String[] args) {
            //Hash code static method
            Byte b1= 123;
            System.out.println("Hash Code = "+Byte.hashCode(b1));
        }
    }

Test it Now

Output:

Hash Code = 123

Example 3

public class JavaByteHashCodeExample3 {
    public static void main(String[] args) {
        byte b1=34;
        //byte is a primitive data type its object can't be used to call Byte class objects.
        int b2=b1.hashCode();
        System.out.println(b2);
    }
}

Test it Now

Output:

Error:(7, 18) java: byte cannot be dereferenced
