Float class hashCode() method

  • hashCode() method is available in java.lang package.
  • hashCode() method is used to return hashcode of the Float object.
  • hashCode() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • hashCode() method does not throw an exception at the time of returning hashcode.

Syntax:

    public int hashCode();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of this method is int, it returns the hash code for this object.

Example:

// Java program to demonstrate the example 
// of int hashCode() method of Float class

public class HashCodeOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float value1 = 30.20f;
        float value2 = 10.20f;

        // It returns hashcode value denoted by this Float f1 object
        // by calling f1.hashCode()
        Float f1 = new Float(value1);

        // Display f1 result
        System.out.println("f1.hashCode(): " + f1.hashCode());

        // It returns hashcode value denoted by this Float f2 object
        // by calling f2.hashCode()
        Float f2 = new Float(value2);

        // Display f2 result
        System.out.println("f2.hashCode(): " + f2.hashCode());
    }
}

Output

f1.hashCode(): 1106352538
f2.hashCode(): 1092825907
