Java Byte hashCode() method

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

Syntax:

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
