Java Float hashCode(float n) Method

The hashCode(float n) method is compatible with Java 1.8 or more version and is a part of the Float Class of the java.lang package. It is used to return the hash code of the float passed as the argument.

This method is compatible with Float.hashCode() method of Float class.

Syntax:

public static int hashCode(float value)  

Parameter:

The parameter includes the float value of which the hash code is to be generated.

Returns:

The unique integer value (hash code) associated with the float value passed as an argument.

Example 1:

Here, using the hashCode(float n) function, the float value passed is converted into its respective hashcode.

import java.lang.Float;

public class StudyTonight

{  
    public static void main(String[] args)  
    {  
        int hv1 = Float.hashCode(27.56930f); //generate the hashcode of the passed argument
        int hv2 = Float.hashCode(-81.4889f); 
        System.out.println("Hash code Value is: " + hv1); 
        System.out.println("Hash code Value is: " + hv2);
    }  
}


Hash code Value is: 1104973293
Hash code Value is: -1029506479

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent hash code.

import java.util.Scanner; 

public class StudyTonight
{  
    public static void main(String[] args)
    {  
      try
      {
         System.out.print("Enter the value: ");  
         Scanner sc = new Scanner(System.in);         
         float i = sc.nextFloat();  
         int hv = Float.hashCode(i);  // Returning hash code value for this object
         System.out.println("Hash code is: " + hv);
           
      }
      catch(Exception e)
      {
        System.out.println("Invalid Input!!");
      }
        
    }  
}  


Enter the value: 5889.034
Hash code is: 1169688646
********************************
Enter the value: -57.067
Hash code is: -1033616228
********************************
Enter the value: 0x67
Invalid Input!!
